Yet how species‐specific organ size and shape are achieved is a fundamental unresolved question in biology. The formation and sculpting of organs begins during embryonic development. As it develops, the spinal cord extends in anterior–posterior direction in synchrony with the overall growth of the body. The dorsoventral (DV) and apicobasal lengths of the spinal cord neuroepithelium also change, while at the same time a characteristic pattern of neural progenitor subtypes along the DV axis is established and elaborated. At the basis of these changes in tissue size and shape are biophysical determinants, such as the change in cell number, cell size and shape, and anisotropic tissue growth. These processes are controlled by global tissue‐scale regulators, such as morphogen signaling gradients as well as mechanical forces. Current challenges in the field are to uncover how these tissue‐scale regulatory mechanisms are translated to the cellular and molecular level, and how regulation of distinct cellular processes gives rise to an overall defined size. Addressing these questions will help not only to achieve a better understanding of how size is controlled, but also of how tissue size is coordinated with the specification of pattern."}],"has_accepted_license":"1","status":"public","external_id":{"isi":["000531419400001"],"pmid":["32391980"]},"scopus_import":"1","oa_version":"Published Version","publication":"Wiley Interdisciplinary Reviews: Developmental Biology","date_created":"2020-05-24T22:01:00Z","type":"journal_article","corr_author":"1","ec_funded":1,"article_type":"original","citation":{"short":"K.

Redox mediators are recognized to be key for improving rechargeability. However, it is unclear how they affect 1O2 formation, which hinders strategies for their improvement. Here we clarify the mechanism of mediated peroxide and superoxide oxidation and thus explain how redox mediators either enhance or suppress 1O2 formation. We show that charging commences with peroxide oxidation to a superoxide intermediate and that redox potentials above ~3.5 V versus Li/Li+ drive 1O2 evolution from superoxide oxidation, while disproportionation always generates some 1O2. We find that 1O2 suppression requires oxidation to be faster than the generation of 1O2 from disproportionation. Oxidation rates decrease with growing driving force following Marcus inverted-region behaviour, establishing a region of maximum rate.","lang":"eng"}],"corr_author":"1","type":"journal_article","scopus_import":"1","publication":"Nature Chemistry","oa_version":"Submitted Version","date_created":"2021-03-16T11:12:20Z","language":[{"iso":"eng"}],"citation":{"mla":"Petit, Yann K., et al. “Mechanism of Mediated Alkali Peroxide Oxidation and Triplet versus Singlet Oxygen Formation.” <i>Nature Chemistry</i>, vol. 13, no. 5, Springer Nature, 2021, pp. 465–71, doi:<a href=\"https://doi.org/10.1038/s41557-021-00643-z\">10.1038/s41557-021-00643-z</a>.","short":"Y.K.

However, this has been achieved at only a limited number of model synapses, including the squid giant synapse and the mammalian calyx of Held. Cortical presynaptic terminals have been largely inaccessible to direct presynaptic recording, due to their small size. Here, we describe a protocol for improved subcellular patch-clamp recording in rat and mouse brain slices, with the synapse in a largely intact environment. Slice preparation takes ~2 h, recording ~3 h and post hoc morphological analysis 2 d. Single presynaptic hippocampal mossy fiber terminals are stimulated minimally invasively in the bouton-attached configuration, in which the cytoplasmic content remains unperturbed, or in the whole-bouton configuration, in which the cytoplasmic composition can be precisely controlled. Paired pre–postsynaptic recordings can be integrated with biocytin labeling and morphological analysis, allowing correlative investigation of synapse structure and function. Paired recordings can be obtained from mossy fiber terminals in slices from both rats and mice, implying applicability to genetically modified synapses. Paired recordings can also be performed together with axon tract stimulation or optogenetic activation, allowing comparison of unitary and compound synaptic events in the same target cell. Finally, paired recordings can be combined with spontaneous event analysis, permitting collection of miniature events generated at a single identified synapse. In conclusion, the subcellular patch-clamp techniques detailed here should facilitate analysis of biophysics, plasticity and circuit function of cortical synapses in the mammalian central nervous system."}],"status":"public","has_accepted_license":"1","external_id":{"pmid":["33990799"],"isi":["000650528700003"]},"project":[{"grant_number":"692692","call_identifier":"H2020","_id":"25B7EB9E-B435-11E9-9278-68D0E5697425","name":"Biophysics and circuit function of a giant cortical glutamatergic synapse"},{"grant_number":"Z00312","name":"Synaptic communication in neuronal microcircuits","call_identifier":"FWF","_id":"25C5A090-B435-11E9-9278-68D0E5697425"},{"name":"Structural plasticity at mossy fiber-CA3 synapses","_id":"2696E7FE-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"V00739"}],"intvolume":"        16","date_updated":"2025-04-22T22:30:43Z","ddc":["570"],"article_processing_charge":"No","publication_identifier":{"eissn":["1750-2799"],"issn":["1754-2189"]},"day":"01","department":[{"_id":"PeJo"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa":1,"title":"Subcellular patch-clamp techniques for single-bouton stimulation and simultaneous pre- and postsynaptic recording at cortical synapses","_id":"9438","date_published":"2021-06-01T00:00:00Z","quality_controlled":"1","acknowledgement":"This project received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement no. 692692 to P.J.) and the Fond zur Förderung der Wissenschaftlichen Forschung (Z 312-B27, Wittgenstein award to P.J., V 739-B27 to C.B.M.).

In a quest for experimental realizations of coherent long-time dynamics, efforts have focused on ergodicity-breaking mechanisms, such as integrability and localization. The recent discovery of persistent revivals in quantum simulators based on Rydberg atoms have pointed to the existence of a new type of behaviour where the system rapidly relaxes for most initial conditions, while certain initial states give rise to non-ergodic dynamics. This collective effect has been named ”quantum many-body scarring’by analogy with a related form of weak ergodicity breaking that occurs for a single particle inside a stadium billiard potential. In this Review, we provide a pedagogical introduction to quantum many-body scars and highlight the emerging connections with the semiclassical quantization of many-body systems. We discuss the relation between scars and more general routes towards weak violations of ergodicity due to embedded algebras and non-thermal eigenstates, and highlight possible applications of scars in quantum technology."}],"type":"journal_article","oa_version":"Preprint","date_created":"2021-05-28T09:03:50Z","publication":"Nature Physics","scopus_import":"1"},{"oa_version":"Published Version","date_created":"2021-05-17T12:31:30Z","corr_author":"1","type":"dissertation","abstract":[{"lang":"eng","text":"Accumulation of interstitial fluid (IF) between embryonic cells is a common phenomenon in vertebrate embryogenesis. Unlike other model systems, where these accumulations coalesce into a large central cavity – the blastocoel, in zebrafish, IF is more uniformly distributed between the deep cells (DC) before the onset of gastrulation. This is likely due to the presence of a large extraembryonic structure – the yolk cell (YC) at the position where the blastocoel typically forms in other model organisms. IF has long been speculated to play a role in tissue morphogenesis during embryogenesis, but direct evidence supporting such function is still sparse. Here we show that the relocalization of IF to the interface between the YC and DC/epiblast is critical for axial mesendoderm (ME) cell protrusion formation and migration along this interface, a key process in embryonic axis formation. We further demonstrate that axial ME cell migration and IF relocalization engage in a positive feedback loop, where axial ME migration triggers IF accumulation ahead of the advancing axial ME tissue by mechanically compressing the overlying epiblast cell layer. Upon compression, locally induced flow relocalizes the IF through the porous epiblast tissue resulting in an IF accumulation ahead of the leading axial ME. This IF accumulation, in turn, promotes cell protrusion formation and migration of the leading axial ME cells, thereby facilitating axial ME extension. Our findings reveal a central role of dynamic IF relocalization in orchestrating germ layer morphogenesis during gastrulation."}],"has_accepted_license":"1","status":"public","citation":{"ieee":"K.

Multiphase flows are more difficult to investigate as their dynamics occur in large parameter space and involve complex phenomena such as preferential concentration, turbulence modulation, non-Newtonian rheology, etc. Over the last few decades, experiments in particle-laden flows have taken a back seat in favour of ever-improving computational resources. However, computers are still not powerful enough to simulate a real-world fluid with millions of finite-size particles. Experiments are essential not only because they offer a reliable way to investigate real-world multiphase flows but also because they serve to validate numerical studies and steer the research in a relevant direction. In this work, we have experimentally investigated particle-laden flows in pipes, and in particular, examined the effect of particles on the laminar-turbulent transition and the drag scaling in turbulent flows.\r\n\r\nFor particle-laden pipe flows, an earlier study [Matas et al., 2003] reported how the sub-critical (i.e., hysteretic) transition that occurs via localised turbulent structures called puffs is affected by the addition of particles. In this study, in addition to this known transition, we found a super-critical transition to a globally fluctuating state with increasing particle concentration. At the same time, the Newtonian-type transition via puffs is delayed to larger Reynolds numbers. At an even higher concentration, only the globally fluctuating state is found. The dynamics of particle-laden flows are hence determined by two competing instabilities that give rise to three flow regimes: Newtonian-type turbulence at low, a particle-induced globally fluctuating state at high, and a coexistence state at intermediate concentrations.\r\n\r\nThe effect of particles on turbulent drag is ambiguous, with studies reporting drag reduction, no net change, and even drag increase. The ambiguity arises because, in addition to particle concentration, particle shape, size, and density also affect the net drag. Even similar particles might affect the flow dissimilarly in different Reynolds number and concentration ranges. In the present study, we explored a wide range of both Reynolds number and concentration, using spherical as well as cylindrical particles. We found that the spherical particles do not reduce drag while the cylindrical particles are drag-reducing within a specific Reynolds number interval. The interval strongly depends on the particle concentration and the relative size of the pipe and particles. Within this interval, the magnitude of drag reduction reaches a maximum. These drag reduction maxima appear to fall onto a distinct power-law curve irrespective of the pipe diameter and particle concentration, and this curve can be considered as the maximum drag reduction asymptote for a given fibre shape. Such an asymptote is well known for polymeric flows but had not been identified for particle-laden flows prior to this work.","lang":"eng"}],"has_accepted_license":"1","status":"public","citation":{"mla":"Agrawal, Nishchal. <i>Transition to Turbulence and Drag Reduction in Particle-Laden Pipe Flows</i>.

Plants do not have blood circulation and their cells cannot move. However, plants have evolved remarkable capacities to regenerate tissues and organs preventing further damage. In my PhD research, I studied the wound healing in the Arabidopsis root. I used a UV laser to ablate single cells in the root tip and observed the consequent wound healing. Interestingly, the inner adjacent cells induced a\r\ndivision plane switch and subsequently adopted the cell type of the killed cell to replace it. We termed this form of wound healing “restorative divisions”. This initial observation triggered the questions of my PhD studies: How and why do cells orient their division planes, how do they feel the wound and why does this happen only in inner adjacent cells.\r\nFor answering these questions, I used a quite simple experimental setup: 5 day - old seedlings were stained with propidium iodide to visualize cell walls and dead cells; ablation was carried out using a special laser cutter and a confocal microscope. Adaptation of the novel vertical microscope system made it possible to observe wounds in real time. This revealed that restorative divisions occur at increased frequency compared to normal divisions. Additionally,\r\nthe major plant hormone auxin accumulates in wound adjacent cells and drives the expression of the wound-stress responsive transcription factor ERF115. Using this as a marker gene for wound responses, we found that an important part of wound signalling is the sensing of the collapse of the ablated cell. The collapse causes a radical pressure drop, which results in strong tissue deformations. These deformations manifest in an invasion of the now free spot specifically by the inner adjacent cells within seconds, probably because of higher pressure of the inner tissues. Long-term imaging revealed that those deformed cells continuously expand towards the wound hole and that this is crucial for the restorative division. These wound-expanding cells exhibit an abnormal, biphasic polarity of microtubule arrays\r\nbefore the division. Experiments inhibiting cell expansion suggest that it is the biphasic stretching that induces those MT arrays. Adapting the micromanipulator aspiration system from animal scientists at our institute confirmed the hypothesis that stretching influences microtubule stability. In conclusion, this shows that microtubules react to tissue deformation\r\nand this facilitates the observed division plane switch. This puts mechanical cues and tensions at the most prominent position for explaining the growth and wound healing properties of plants. Hence, it shines light onto the importance of understanding mechanical signal transduction.

In large cells like oocytes, these reorganizations become crucial in patterning the oocyte for later stages of embryonic development. Ascidians oocytes reorganize their cytoplasm (ooplasm) in a spectacular manner. Ooplasmic reorganization is initiated at fertilization with the contraction of the actomyosin cortex along the animal-vegetal axis of the oocyte, driving the accumulation of cortical endoplasmic reticulum (cER), maternal mRNAs associated to it and a mitochondria-rich subcortical layer – the myoplasm – in a region of the vegetal pole termed contraction pole (CP). Here we have used the species Phallusia mammillata to investigate the changes in cell shape that accompany these reorganizations and the mechanochemical mechanisms underlining CP formation.\r\nWe report that the length of the animal-vegetal (AV) axis oscillates upon fertilization: it first undergoes a cycle of fast elongation-lengthening followed by a slow expansion of mainly the vegetal pole (VP) of the cell. We show that the fast oscillation corresponds to a dynamic polarization of the actin cortex as a result of a fertilization-induced increase in cortical tension in the oocyte that triggers a rupture of the cortex at the animal pole and the establishment of vegetal-directed cortical flows. These flows are responsible for the vegetal accumulation of actin causing the VP to flatten. \r\nWe find that the slow expansion of the VP, leading to CP formation, correlates with a relaxation of the vegetal cortex and that the myoplasm plays a role in the expansion. We show that the myoplasm is a solid-like layer that buckles under compression forces arising from the contracting actin cortex at the VP. Straightening of the myoplasm when actin flows stops, facilitates the expansion of the VP and the CP. Altogether, our results present a previously unrecognized role for the myoplasm in ascidian ooplasmic segregation. \r\n"}],"type":"dissertation","corr_author":"1","oa_version":"Published Version","date_created":"2021-07-01T14:50:17Z","language":[{"iso":"eng"}],"citation":{"short":"S.

Thus, the host immune response is faced with a non-trivial problem – accommodate beneficial commensals and remove harmful pathogens. This is especially difficult as molecular patterns, such as lipopolysaccharide or specific surface organelles such as pili, are conserved in both, commensal and pathogenic bacteria. Type 1 pili, tightly regulated by phase variation, are considered an important virulence factor of pathogenic bacteria as they facilitate invasion into host cells. While invasion represents a de facto passive mechanism for pathogens to escape the host immune response, we demonstrate a fundamental role of type 1 pili as active modulators of the innate and adaptive immune response.","lang":"eng"}],"OA_place":"publisher","ddc":["570"],"date_updated":"2026-07-06T12:48:19Z","page":"73","alternative_title":["ISTA Thesis"],"author":[{"id":"3AEC8556-F248-11E8-B48F-1D18A9856A87","full_name":"Tomasek, Kathrin","last_name":"Tomasek","first_name":"Kathrin","orcid":"0000-0003-3768-877X"}],"acknowledged_ssus":[{"_id":"LifeSc"},{"_id":"Bio"},{"_id":"PreCl"},{"_id":"EM-Fac"}],"related_material":{"record":[{"relation":"part_of_dissertation","status":"public","id":"10316"}]},"month":"11","year":"2021","publication_status":"published","file_date_updated":"2022-12-20T23:30:05Z","date_published":"2021-11-18T00:00:00Z","_id":"10307","supervisor":[{"first_name":"Michael K","orcid":"0000-0002-4561-241X","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","full_name":"Sixt, Michael K"},{"last_name":"Guet","first_name":"Calin C","orcid":"0000-0001-6220-2052","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","full_name":"Guet, Calin C"}],"file":[{"access_level":"open_access","creator":"ktomasek","relation":"main_file","content_type":"application/pdf","date_created":"2021-11-18T15:07:31Z","file_size":13266088,"file_id":"10308","file_name":"ThesisTomasekKathrin.pdf","embargo":"2022-11-18","date_updated":"2022-12-20T23:30:05Z","checksum":"b39c9e0ef18d0484d537a67551effd02"},{"file_size":7539509,"embargo_to":"open_access","checksum":"c0c440ee9e5ef1102a518a4f9f023e7c","date_updated":"2022-12-20T23:30:05Z","file_name":"ThesisTomasekKathrin.docx","file_id":"10309","relation":"source_file","creator":"ktomasek","access_level":"closed","content_type":"application/vnd.openxmlformats-officedocument.wordprocessingml.document","date_created":"2021-11-18T15:07:46Z"}],"doi":"10.15479/at:ista:10307","publisher":"Institute of Science and Technology Austria","degree_awarded":"PhD","article_processing_charge":"No","publication_identifier":{"issn":["2663-337X"]},"day":"18","department":[{"_id":"MiSi"},{"_id":"CaGu"},{"_id":"GradSch"}],"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","title":"Pathogenic Escherichia coli hijack the host immune response","oa":1},{"scopus_import":"1","publication":"Developmental Cell","date_created":"2021-01-17T23:01:10Z","oa_version":"Published Version","main_file_link":[{"url":"https://doi.org/10.1016/j.devcel.2020.12.002","open_access":"1"}],"corr_author":"1","type":"journal_article","abstract":[{"lang":"eng","text":"Cytoplasm is a gel-like crowded environment composed of various macromolecules, organelles, cytoskeletal networks, and cytosol. The structure of the cytoplasm is highly organized and heterogeneous due to the crowding of its constituents and their effective compartmentalization. In such an environment, the diffusive dynamics of the molecules are restricted, an effect that is further amplified by clustering and anchoring of molecules. Despite the crowded nature of the cytoplasm at the microscopic scale, large-scale reorganization of the cytoplasm is essential for important cellular functions, such as cell division and polarization. How such mesoscale reorganization of the cytoplasm is achieved, especially for large cells such as oocytes or syncytial tissues that can span hundreds of micrometers in size, is only beginning to be understood. In this review, we will discuss recent advances in elucidating the molecular, cellular, and biophysical mechanisms by which the cytoskeleton drives cytoplasmic reorganization across different scales, structures, and species."}],"external_id":{"isi":["000613273900009"],"pmid":["33321104"]},"status":"public","citation":{"ama":"Shamipour S, Caballero Mancebo S, Heisenberg C-PJ.

Many Enterobacteriaceae express type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and establish persistent infections. However, the molecular mechanisms and strategies by which bacteria actively circumvent the immune response of the host remain poorly understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide detection, on dendritic cells as a previously undescribed binding partner of FimH, the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH amino acids involved in CD14 binding are highly conserved across pathogenic and non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced dendritic cell migration and blunted expression of co-stimulatory molecules, both rate-limiting factors of T cell activation. While defining an active molecular mechanism of immune evasion by pathogens, the interaction between FimH and CD14 represents a potential target to interfere with persistent and recurrent infections, such as urinary tract infections or Crohn’s disease.","lang":"eng"}],"corr_author":"1","type":"preprint","main_file_link":[{"url":"https://www.biorxiv.org/content/10.1101/2021.10.18.464770v1","open_access":"1"}],"date_created":"2021-11-19T12:24:16Z","oa_version":"Preprint","publication":"bioRxiv","department":[{"_id":"CaGu"},{"_id":"MiSi"}],"month":"10","day":"18","related_material":{"record":[{"relation":"later_version","id":"11843","status":"public"},{"relation":"dissertation_contains","id":"10307","status":"public"}]},"title":"Type 1 piliated uropathogenic Escherichia coli hijack the host immune response by binding to CD14","oa":1,"publication_status":"draft","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2021","article_processing_charge":"No","author":[{"full_name":"Tomasek, Kathrin","id":"3AEC8556-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-3768-877X","first_name":"Kathrin","last_name":"Tomasek"},{"id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","full_name":"Leithner, Alexander F","first_name":"Alexander F","orcid":"0000-0002-1073-744X","last_name":"Leithner"},{"id":"727b3c7d-4939-11ec-89b3-b9b0750ab74d","full_name":"Glatzová, Ivana","last_name":"Glatzová","first_name":"Ivana"},{"first_name":"Michael S.","last_name":"Lukesch","full_name":"Lukesch, Michael S."},{"full_name":"Guet, Calin C","id":"47F8433E-F248-11E8-B48F-1D18A9856A87","last_name":"Guet","orcid":"0000-0001-6220-2052","first_name":"Calin C"},{"first_name":"Michael K","orcid":"0000-0002-4561-241X","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","full_name":"Sixt, Michael K"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"PreCl"},{"_id":"EM-Fac"}]},{"tmp":{"short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png"},"article_processing_charge":"No","author":[{"full_name":"Nardin, Michele","id":"30BD0376-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8849-6570","first_name":"Michele","last_name":"Nardin"},{"last_name":"Csicsvari","orcid":"0000-0002-5193-4036","first_name":"Jozsef L","full_name":"Csicsvari, Jozsef L","id":"3FA14672-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Gašper","orcid":"0000-0002-6699-1455","last_name":"Tkačik","id":"3D494DCA-F248-11E8-B48F-1D18A9856A87","full_name":"Tkačik, Gašper"},{"first_name":"Cristina","last_name":"Savin","id":"3933349E-F248-11E8-B48F-1D18A9856A87","full_name":"Savin, Cristina"}],"month":"09","department":[{"_id":"GradSch"},{"_id":"JoCs"},{"_id":"GaTk"}],"day":"29","related_material":{"record":[{"status":"public","id":"11932","relation":"dissertation_contains"},{"relation":"later_version","id":"14656","status":"public"}]},"oa":1,"publication_status":"draft","title":"The structure of hippocampal CA1 interactions optimizes spatial coding across experience","year":"2021","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","ec_funded":1,"citation":{"short":"M.

Using a novel statistical estimator and theoretical modeling, both developed in the framework of maximum entropy models, we reveal highly structured cell-to-cell interactions whose statistics depend on familiar vs. novel environment. In both conditions the circuit interactions optimize the encoding of spatial information, but for regimes that differ in the signal-to-noise ratio of their spatial inputs. Moreover, the topology of the interactions facilitates linear decodability, making the information easy to read out by downstream circuits.

Different parts of their ZW sex chromosomes have stopped recombining in distinct lineages, creating “evolutionary strata” of various ages. Although the Z-chromosome is well characterized at the genomic and molecular level, the W-chromosome has remained largely unstudied from an evolutionary perspective, as only a few W-linked genes have been detected outside of the model species Schistosoma mansoni. Here, we characterize the gene content and evolution of the W-chromosomes of S. mansoni and of the divergent species S. japonicum. We use a combined RNA/DNA k-mer based pipeline to assemble around 100 candidate W-specific transcripts in each of the species. About half of them map to known protein coding genes, the majority homologous to S. mansoni Z-linked genes. We perform an extended analysis of the evolutionary strata present in the two species (including characterizing a previously undetected young stratum in S. japonicum) to infer patterns of sequence and expression evolution of W-linked genes at different time points after recombination was lost. W-linked genes show evidence of degeneration, including high rates of protein evolution and reduced expression. Most are found in young lineage-specific strata, with only a few high expression ancestral W-genes remaining, consistent with the progressive erosion of nonrecombining regions. Among these, the splicing factor u2af2 stands out as a promising candidate for primary sex determination, opening new avenues for understanding the molecular basis of the reproductive biology of this group."}]},{"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"author":[{"first_name":"Daniel","orcid":"0000-0002-7197-4801","last_name":"Jirovec","id":"4C473F58-F248-11E8-B48F-1D18A9856A87","full_name":"Jirovec, Daniel"},{"id":"340F461A-F248-11E8-B48F-1D18A9856A87","full_name":"Hofmann, Andrea C","first_name":"Andrea C","last_name":"Hofmann"},{"full_name":"Ballabio, Andrea","first_name":"Andrea","last_name":"Ballabio"},{"full_name":"Mutter, Philipp M.","last_name":"Mutter","first_name":"Philipp M."},{"full_name":"Tavani, Giulio","last_name":"Tavani","first_name":"Giulio"},{"first_name":"Marc","last_name":"Botifoll","full_name":"Botifoll, Marc"},{"orcid":"0000-0002-2968-611X","first_name":"Alessandro","last_name":"Crippa","full_name":"Crippa, Alessandro","id":"1F2B21A2-F6E7-11E9-9B82-F7DBE5697425"},{"id":"3F5D8856-F248-11E8-B48F-1D18A9856A87","full_name":"Kukucka, Josip","first_name":"Josip","last_name":"Kukucka"},{"first_name":"Oliver","last_name":"Sagi","id":"71616374-A8E9-11E9-A7CA-09ECE5697425","full_name":"Sagi, Oliver"},{"first_name":"Frederico","orcid":"0000-0003-2668-2401","last_name":"Martins","id":"38F80F9A-1CB8-11EA-BC76-B49B3DDC885E","full_name":"Martins, Frederico"},{"full_name":"Saez Mollejo, Jaime","id":"e0390f72-f6e0-11ea-865d-862393336714","last_name":"Saez Mollejo","first_name":"Jaime"},{"full_name":"Prieto Gonzalez, Ivan","id":"2A307FE2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-7370-5357","first_name":"Ivan","last_name":"Prieto Gonzalez"},{"first_name":"Maksim","last_name":"Borovkov","full_name":"Borovkov, Maksim","id":"2ac7a0a2-3562-11eb-9256-fbd18ea55087"},{"full_name":"Arbiol, Jordi","last_name":"Arbiol","first_name":"Jordi"},{"last_name":"Chrastina","first_name":"Daniel","full_name":"Chrastina, Daniel"},{"first_name":"Giovanni","last_name":"Isella","full_name":"Isella, Giovanni"},{"first_name":"Georgios","orcid":"0000-0001-8342-202X","last_name":"Katsaros","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","full_name":"Katsaros, Georgios"}],"pmid":1,"page":"1106–1112","year":"2021","publication_status":"published","issue":"8","related_material":{"link":[{"description":"News on IST Homepage","relation":"press_release","url":"https://ist.ac.at/en/news/quantum-computing-with-holes/"}],"record":[{"relation":"research_data","status":"public","id":"9323"},{"relation":"dissertation_contains","status":"public","id":"10058"}]},"volume":20,"month":"08","date_created":"2020-12-02T10:50:47Z","publication":"Nature Materials","scopus_import":"1","oa_version":"Preprint","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2011.13755"}],"type":"journal_article","corr_author":"1","abstract":[{"lang":"eng","text":"Spin qubits are considered to be among the most promising candidates for building a quantum processor. Group IV hole spin qubits have moved into the focus of interest due to the ease of operation and compatibility with Si technology. In addition, Ge offers the option for monolithic superconductor-semiconductor integration. Here we demonstrate a hole spin qubit operating at fields below 10 mT, the critical field of Al, by exploiting the large out-of-plane hole g-factors in planar Ge and by encoding the qubit into the singlet-triplet states of a double quantum dot. We observe electrically controlled X and Z-rotations with tunable frequencies exceeding 100 MHz and dephasing times of 1μs which we extend beyond 15μs with echo techniques. These results show that Ge hole singlet triplet qubits outperform their electronic Si and GaAs based counterparts in speed and coherence, respectively. In addition, they are on par with Ge single spin qubits, but can be operated at much lower fields underlining their potential for on chip integration with superconducting technologies."}],"status":"public","external_id":{"pmid":["34083775"],"isi":["000657596400001"],"arxiv":["2011.13755"]},"citation":{"ista":"Jirovec D, Hofmann AC, Ballabio A, Mutter PM, Tavani G, Botifoll M, Crippa A, Kukucka J, Sagi O, Martins F, Saez Mollejo J, Prieto Gonzalez I, Borovkov M, Arbiol J, Chrastina D, Isella G, Katsaros G. 2021.

As large multinational companies and international funds are heavily investing in quantum technologies it is still a question which platform is best suited for the task of realizing a scalable quantum processor. In this work we investigate hole spins in Ge quantum wells. These hold great promise as they possess several favorable properties: a small effective mass, a strong spin-orbit coupling, long relaxation time and an inherent immunity to hyperfine noise. All these characteristics helped Ge hole spin qubits to evolve from a single qubit to a fully entangled four qubit processor in only 3 years. Here, we investigated a qubit approach leveraging the large out-of-plane g-factors of heavy hole states in Ge quantum dots. We found this qubit to be reproducibly operable at extremely low magnetic field and at large speeds while maintaining coherence. This was possible because large differences of g-factors in adjacent dots can be achieved in the out-of-plane direction. In the in-plane direction the small g-factors, on the other hand, can be altered very effectively by the confinement potentials. Here, we found that this can even lead to a sign change of the g-factors. The resulting g-factor difference alters the dynamics of the system drastically and produces effects typically attributed to a spin-orbit induced spin-flip term.  The investigations carried out in this thesis give further insights into the possibilities of holes in Ge and reveal new physical properties that need to be considered when designing future spin qubit experiments.","lang":"eng"}],"has_accepted_license":"1","status":"public","citation":{"chicago":"Jirovec, Daniel. “Singlet-Triplet Qubits and Spin-Orbit Interaction in 2-Dimensional Ge Hole Gases.” Institute of Science and Technology Austria, 2021. <a href=\"https://doi.org/10.15479/at:ista:10058\">https://doi.org/10.15479/at:ista:10058</a>.","mla":"Jirovec, Daniel. <i>Singlet-Triplet Qubits and Spin-Orbit Interaction in 2-Dimensional Ge Hole Gases</i>.

A possible candidate for a component of additional auxin perception mechanisms is the AUXIN BINDING PROTEIN 1 (ABP1), whose function in planta remains unclear.\r\nHere we combined expression analysis with gain- and loss-of-function approaches to analyze the role of ABP1 in plant development. ABP1 shows a broad expression largely overlapping with, but not regulated by, transcriptional auxin response activity. Furthermore, ABP1 activity is not essential for the transcriptional auxin signaling. Genetic in planta analysis revealed that abp1 loss-of-function mutants show largely normal development with minor defects in bolting. On the other hand, ABP1 gain-of-function alleles show a broad range of growth and developmental defects, including root and hypocotyl growth and bending, lateral root and leaf development, bolting, as well as response to heat stress. At the cellular level, ABP1 gain-of-function leads to impaired auxin effect on PIN polar distribution and affects BFA-sensitive PIN intracellular aggregation.\r\nThe gain-of-function analysis suggests a broad, but still mechanistically unclear involvement of ABP1 in plant development, possibly masked in abp1 loss-of-function mutants by a functional redundancy.","lang":"eng"}],"status":"public","has_accepted_license":"1","external_id":{"isi":["000614154500001"],"pmid":["33487339"]},"article_type":"original","ec_funded":1,"citation":{"mla":"Gelová, Zuzana, et al. “Developmental Roles of Auxin Binding Protein 1 in Arabidopsis Thaliana.” <i>Plant Science</i>, vol. 303, 110750, Elsevier, 2021, doi:<a href=\"https://doi.org/10.1016/j.plantsci.2020.110750\">10.1016/j.plantsci.2020.110750</a>.","short":"Z.

However, a mechanistic understanding of auxin-mediated feedback on endocytosis and polar distribution of PIN auxin transporters remains limited due to contradictory observations and interpretations. Here, we used state-of-the-art methods to reexamine the\r\nauxin effects on PIN endocytic trafficking. We used high auxin concentrations or longer treatments versus lower concentrations and shorter treatments of natural (IAA) and synthetic (NAA) auxins to distinguish between specific and nonspecific effects. Longer treatments of both auxins interfere with Brefeldin A-mediated intracellular PIN2 accumulation and also with general aggregation of endomembrane compartments. NAA treatment decreased the internalization of the endocytic tracer dye, FM4-64; however, NAA treatment also affected the number, distribution, and compartment identity of the early endosome/trans-Golgi network (EE/TGN), rendering the FM4-64 endocytic assays at high NAA concentrations unreliable. To circumvent these nonspecific effects of NAA and IAA affecting the endomembrane system, we opted for alternative approaches visualizing the endocytic events directly at the plasma membrane (PM). Using Total Internal Reflection Fluorescence (TIRF) microscopy, we saw no significant effects of IAA or NAA treatments on the incidence and dynamics of clathrin foci, implying that these treatments do not affect the overall endocytosis rate. However, both NAA and IAA at low concentrations rapidly and specifically promoted endocytosis of photo-converted PIN2 from the PM. These analyses identify a specific effect of NAA and IAA on PIN2 endocytosis, thus contributing to its\r\npolarity maintenance and furthermore illustrate that high auxin levels have nonspecific effects on trafficking and endomembrane compartments.

Relatively fast motions include water-driven growth as exemplified by root cell expansion under abiotic/biotic stresses or during gravitropism. A showcase is a root growth inhibition in 30 seconds triggered by the phytohormone auxin. However, the cellular and molecular mechanisms are still largely unknown. This thesis covers the studies about this topic as follows. By taking advantage of microfluidics combined with live imaging, pharmaceutical tools, and transgenic lines, we examined the kinetics of and causal relationship among various auxininduced rapid cellular changes in root growth, apoplastic pH, cytosolic Ca2+, cortical microtubule (CMT) orientation, and vacuolar morphology. We revealed that CMT reorientation and vacuolar constriction are the consequence of growth itself instead of responding directly to auxin. In contrast, auxin induces apoplast alkalinization to rapidly inhibit root growth in 30 seconds. This auxin-triggered apoplast alkalinization results from rapid H+- influx that is contributed by Ca2+ inward channel CYCLIC NUCLEOTIDE-GATED CHANNEL 14 (CNGC14)-dependent Ca2+ signaling. To dissect which auxin signaling mediates the rapid apoplast alkalinization, we\r\ncombined microfluidics and genetic engineering to verify that TIR1/AFB receptors conduct a non-transcriptional regulation on Ca2+ and H+ -influx. This non-canonical pathway is mostly mediated by the cytosolic portion of TIR1/AFB. On the other hand, we uncovered, using biochemical and phospho-proteomic analysis, that auxin cell surface signaling component TRANSMEMBRANE KINASE 1 (TMK1) plays a negative role during auxin-trigger apoplast\r\nalkalinization and root growth inhibition through directly activating PM H+ -ATPases. Therefore, we discovered that PM H+ -ATPases counteract instead of mediate the auxintriggered rapid H+ -influx, and that TIR1/AFB and TMK1 regulate root growth antagonistically. This opposite effect of TIR1/AFB and TMK1 is consistent during auxin-induced hypocotyl elongation, leading us to explore the relation of two signaling pathways. Assisted with biochemistry and fluorescent imaging, we verified for the first time that TIR1/AFB and TMK1 can interact with each other. The ability of TIR1/AFB binding to membrane lipid provides a basis for the interaction of plasma membrane- and cytosol-localized proteins.\r\nBesides, transgenic analysis combined with genetic engineering and biochemistry showed that  vi\r\nthey do function in the same pathway. Particularly, auxin-induced TMK1 increase is TIR1/AFB dependent, suggesting TIR1/AFB regulation on TMK1. Conversely, TMK1 also regulates TIR1/AFB protein levels and thus auxin canonical signaling. To follow the study of rapid growth regulation, we analyzed another rapid growth regulator, signaling peptide RALF1. We showed that RALF1 also triggers a rapid and reversible growth inhibition caused by H + influx, highly resembling but not dependent on auxin. Besides, RALF1 promotes auxin biosynthesis by increasing expression of auxin biosynthesis enzyme YUCCAs and thus induces auxin signaling in ca. 1 hour, contributing to the sustained RALF1-triggered growth inhibition. These studies collectively contribute to understanding rapid regulation on plant cell\r\ngrowth, novel auxin signaling pathway as well as auxin-peptide crosstalk.

From the phosphoproteome data, we pinpointed (novel) growth regulators, such as the RALF34-THE1 module.
