[{"publication":"iScience","issue":"10","day":"20","abstract":[{"lang":"eng","text":"Sleep plays a key role in preserving brain function, keeping the brain network in a state that ensures optimal computational capabilities. Empirical evidence indicates that such a state is consistent with criticality, where scale-free neuronal avalanches emerge. However, the relationship between sleep, emergent avalanches, and criticality remains poorly understood. Here we fully characterize the critical behavior of avalanches during sleep, and study their relationship with the sleep macro- and micro-architecture, in particular the cyclic alternating pattern (CAP). We show that avalanche size and duration distributions exhibit robust power laws with exponents approximately equal to −3/2 e −2, respectively. Importantly, we find that sizes scale as a power law of the durations, and that all critical exponents for neuronal avalanches obey robust scaling relations, which are consistent with the mean-field directed percolation universality class. Our analysis demonstrates that avalanche dynamics depends on the position within the NREM-REM cycles, with the avalanche density increasing in the descending phases and decreasing in the ascending phases of sleep cycles. Moreover, we show that, within NREM sleep, avalanche occurrence correlates with CAP activation phases, particularly A1, which are the expression of slow wave sleep propensity and have been proposed to be beneficial for cognitive processes. The results suggest that neuronal avalanches, and thus tuning to criticality, actively contribute to sleep development and play a role in preserving network function. Such findings, alongside characterization of the universality class for avalanches, open new avenues to the investigation of functional role of criticality during sleep with potential clinical application.</jats:p><jats:sec><jats:title>Significance statement</jats:title><jats:p>We fully characterize the critical behavior of neuronal avalanches during sleep, and show that avalanches follow precise scaling laws that are consistent with the mean-field directed percolation universality class. The analysis provides first evidence of a functional relationship between avalanche occurrence, slow-wave sleep dynamics, sleep stage transitions and occurrence of CAP phase A during NREM sleep. Because CAP is considered one of the major guardians of NREM sleep that allows the brain to dynamically react to external perturbation and contributes to the cognitive consolidation processes occurring in sleep, our observations suggest that neuronal avalanches at criticality are associated with flexible response to external inputs and to cognitive processes, a key assumption of the critical brain hypothesis."}],"ddc":["570"],"project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020"},{"_id":"eb943429-77a9-11ec-83b8-9f471cdf5c67","name":"Functional Advantages of Critical Brain Dynamics","grant_number":"M03318"}],"ec_funded":1,"oa_version":"Published Version","has_accepted_license":"1","publication_status":"published","scopus_import":"1","file":[{"access_level":"open_access","relation":"main_file","date_updated":"2023-10-09T07:23:46Z","date_created":"2023-10-09T07:23:46Z","checksum":"f499836af172ecc9865de4bb41fa99d1","creator":"dernst","file_id":"14412","success":1,"file_name":"2023_iScience_Scarpetta.pdf","file_size":4872708,"content_type":"application/pdf"}],"department":[{"_id":"GaTk"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"title":"Criticality of neuronal avalanches in human sleep and their relationship with sleep macro- and micro-architecture","author":[{"last_name":"Scarpetta","full_name":"Scarpetta, Silvia","first_name":"Silvia"},{"full_name":"Morrisi, Niccolò","first_name":"Niccolò","last_name":"Morrisi"},{"full_name":"Mutti, Carlotta","last_name":"Mutti","first_name":"Carlotta"},{"first_name":"Nicoletta","full_name":"Azzi, Nicoletta","last_name":"Azzi"},{"last_name":"Trippi","first_name":"Irene","full_name":"Trippi, Irene"},{"last_name":"Ciliento","full_name":"Ciliento, Rosario","first_name":"Rosario"},{"first_name":"Ilenia","full_name":"Apicella, Ilenia","last_name":"Apicella"},{"last_name":"Messuti","full_name":"Messuti, Giovanni","first_name":"Giovanni"},{"last_name":"Angiolelli","full_name":"Angiolelli, Marianna","first_name":"Marianna"},{"id":"A057D288-3E88-11E9-986D-0CF4E5697425","first_name":"Fabrizio","last_name":"Lombardi","full_name":"Lombardi, Fabrizio","orcid":"0000-0003-2623-5249"},{"full_name":"Parrino, Liborio","last_name":"Parrino","first_name":"Liborio"},{"last_name":"Vaudano","full_name":"Vaudano, Anna Elisabetta","first_name":"Anna Elisabetta"}],"license":"https://creativecommons.org/licenses/by/4.0/","external_id":{"pmid":["37766992"],"isi":["001082331200001"]},"isi":1,"article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"12487","page":"107840","pmid":1,"year":"2023","doi":"10.1016/j.isci.2023.107840","acknowledgement":"FL acknowledges support from the European Union’s Horizon 2020 research and innovation program under the Marie Sklodowska-Curie Grant Agreement No. 754411, and from the Austrian Science Fund (FWF) under the Lise Meitner fellowship No. PT1013M03318.

We studied aromatic residues in the two structurally homologous cross-β amyloid fibrils HET-s, and  HELLF by employing a specific isotope-labeling approach and magic-angle-spinning NMR. The dynamic behavior of the aromatic residues Phe and Tyr indicates that the hydrophobic amyloid core is rigid, without any sign of \"breathing motions\" over hundreds of milliseconds at least. Aromatic residues exposed at the fibril surface have a rigid ring axis but undergo ring flips on a variety of time scales from nanoseconds to microseconds. Our approach provides direct insight into hydrophobic-core motions, enabling a better evaluation of the conformational heterogeneity generated from an NMR structural ensemble of such amyloid cross-β architecture.","lang":"eng"}],"day":"23","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","contributor":[{"last_name":"Berbon","contributor_type":"researcher","first_name":"Mélanie"},{"last_name":"Vallet","first_name":"Alicia","contributor_type":"researcher"},{"last_name":"Grelard","first_name":"Axelle","contributor_type":"researcher"},{"last_name":"Morvan","contributor_type":"researcher","first_name":"Estelle"},{"last_name":"Bardiaux","first_name":"Benjamin","contributor_type":"researcher"},{"first_name":"Roman","last_name":"Lichtenecker","contributor_type":"researcher"},{"contributor_type":"researcher","last_name":"Ernst","first_name":"Matthias"},{"first_name":"Antoine","last_name":"Loquet","contributor_type":"researcher"},{"contributor_type":"contact_person","last_name":"Schanda","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","first_name":"Paul","orcid":"0000-0002-9350-7606"},{"orcid":"0000-0002-6401-5151","contributor_type":"researcher","last_name":"Becker","id":"36336939-eb97-11eb-a6c2-c83f1214ca79","first_name":"Lea Marie"}],"_id":"12497","oa_version":"Published Version","year":"2023","doi":"10.15479/AT:ISTA:12497","related_material":{"record":[{"status":"public","relation":"used_in_publication","id":"12675"}]},"has_accepted_license":"1","date_updated":"2024-10-21T06:01:38Z","type":"research_data","corr_author":"1","publisher":"Institute of Science and Technology Austria","keyword":["aromatic side chains","isotopic labeling","protein dynamics","ring flips","spin relaxation"],"status":"public","file":[{"file_name":"Research_Data.zip","checksum":"fd9a28620a81a82991fb70f4fd6591d9","creator":"lbecker","file_id":"12743","date_created":"2023-03-23T10:03:16Z","access_level":"open_access","relation":"main_file","date_updated":"2023-03-24T09:34:20Z","content_type":"application/zip","file_size":87018103},{"file_size":747,"content_type":"text/plain","file_name":"README.txt","date_updated":"2023-03-24T09:42:03Z","relation":"main_file","access_level":"open_access","date_created":"2023-03-24T07:13:55Z","file_id":"12755","checksum":"30ebdfb600af118fcf8518b6efe0b7e9","creator":"dernst"}],"oa":1,"month":"03","article_processing_charge":"No","citation":{"ieee":"L.

It emphasizes speciation as a continuous process that may be studied by comparing contemporary population pairs that show differing levels of divergence. In their recent perspective article in Evolution, Stankowski and Ravinet provided a valuable service by formally defining the speciation continuum as a continuum of reproductive isolation, based on opinions gathered from a survey of speciation researchers. While we agree that the speciation continuum has been a useful concept to advance the understanding of the speciation process, some intrinsic limitations exist. Here, we advocate for a multivariate extension, the speciation hypercube, first proposed by Dieckmann et al. in 2004, but rarely used since. We extend the idea of the speciation cube and suggest it has strong conceptual and practical advantages over a one-dimensional model. We illustrate how the speciation hypercube can be used to visualize and compare different speciation trajectories, providing new insights into the processes and mechanisms of speciation. A key strength of the speciation hypercube is that it provides a unifying framework for speciation research, as it allows questions from apparently disparate subfields to be addressed in a single conceptual model.","lang":"eng"}],"publication_status":"published","scopus_import":"1","title":"A multivariate view of the speciation continuum","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/evolut/qpac004"}],"department":[{"_id":"NiBa"}],"external_id":{"isi":["001021686300024"],"pmid":["36622661"]},"author":[{"last_name":"Bolnick","full_name":"Bolnick, Daniel I.","first_name":"Daniel I."},{"last_name":"Hund","full_name":"Hund, Amanda K.","first_name":"Amanda K."},{"last_name":"Nosil","full_name":"Nosil, Patrik","first_name":"Patrik"},{"last_name":"Peng","first_name":"Foen","full_name":"Peng, Foen"},{"first_name":"Mark","full_name":"Ravinet, Mark","last_name":"Ravinet"},{"id":"43161670-5719-11EA-8025-FABC3DDC885E","last_name":"Stankowski","full_name":"Stankowski, Sean","first_name":"Sean"},{"full_name":"Subramanian, Swapna","last_name":"Subramanian","first_name":"Swapna"},{"last_name":"Wolf","full_name":"Wolf, Jochen B.W.","first_name":"Jochen B.W."},{"first_name":"Roman","last_name":"Yukilevich","full_name":"Yukilevich, Roman"}]},{"oa":1,"month":"01","volume":16,"article_processing_charge":"No","citation":{"ama":"Ortiz-Leal I, Torres MV, Vargas Barroso VM, et al.

In addition to the main olfactory system and the vomeronasal system, a range of olfactory subsystems converge onto the transition zone located between the main olfactory bulb (MOB) and the accessory olfactory bulb (AOB), which has been termed the olfactory limbus (OL). The OL contains specialized glomeruli that receive noncanonical sensory afferences and which interact with the MOB and AOB. Little is known regarding the olfactory subsystems of mammals other than laboratory rodents.\r\nMethods: We have focused on characterizing the OL in the red fox by performing general and specific histological stainings on serial sections, using both single and double immunohistochemical and lectin-histochemical labeling techniques.\r\nResults: As a result, we have been able to determine that the OL of the red fox (Vulpes vulpes) displays an uncommonly high degree of development and complexity.\r\nDiscussion: This makes this species a novel mammalian model, the study of which could improve our understanding of the noncanonical pathways involved in the processing of chemosensory cues."}],"day":"10","ddc":["570"],"oa_version":"Published Version","article_number":"1097467","has_accepted_license":"1","publication_status":"published","scopus_import":"1"},{"language":[{"iso":"eng"}],"quality_controlled":"1","publication_identifier":{"issn":["2643-1564"]},"date_created":"2023-02-10T09:02:26Z","oa":1,"month":"01","volume":5,"article_processing_charge":"No","citation":{"ista":"Ghazaryan A, Cappellaro A, Lemeshko M, Volosniev A. 2023.

Here, we discuss a Caldeira-Leggett-type model that can be used to propose and interpret quantum simulators of this problem in cold Bose gases. First, we derive a master equation that describes the model and explore it in a one-dimensional (1D) setting. To validate the standard assumptions needed for our derivation, we analyze available experimental data without SOC; as a byproduct, this analysis suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron approach at temperatures currently accessible in a cold-atom laboratory—motion of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the information about SOC is incorporated in the initial conditions. Observables sensitive to this information (such as spin densities) can be used to study formation of steady spin polarization domains during quench dynamics.","lang":"eng"}],"ddc":["530"],"project":[{"grant_number":"801770","_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle"}],"ec_funded":1,"oa_version":"Published Version"},{"external_id":{"pmid":["36731425"],"isi":["000994473300001"]},"author":[{"orcid":"0000-0002-5615-5277","last_name":"Villalba Requena","full_name":"Villalba Requena, Ana","id":"68cb85a0-39f7-11eb-9559-9aaab4f6a247","first_name":"Ana"},{"full_name":"Hippenmeyer, Simon","id":"37B36620-F248-11E8-B48F-1D18A9856A87","first_name":"Simon","last_name":"Hippenmeyer","orcid":"0000-0003-2279-1061"}],"title":"Going back in time with TEMPO","main_file_link":[{"url":"https://doi.org/10.1016/j.neuron.2023.01.006","open_access":"1"}],"department":[{"_id":"SiHi"}],"publication_status":"published","corr_author":"1","scopus_import":"1","OA_place":"publisher","oa_version":"Published Version","issue":"3","publication":"Neuron","abstract":[{"text":"In this issue of Neuron, Espinosa-Medina et al.1 present the TEMPO (Temporal Encoding and Manipulation in a Predefined Order) system, which enables the marking and genetic manipulation of sequentially generated cell lineages in vertebrate species in vivo.","lang":"eng"}],"day":"01","date_created":"2023-02-12T23:00:58Z","language":[{"iso":"eng"}],"quality_controlled":"1","publication_identifier":{"eissn":["1097-4199"]},"date_published":"2023-02-01T00:00:00Z","volume":111,"month":"02","article_processing_charge":"No","oa":1,"citation":{"ista":"Villalba Requena A, Hippenmeyer S. 2023.

Despite substantial effects on pathogen fitness and epidemiology, it is still largely unknown how pathogens react to the selection pressure imposed by care intervention. Using social insects and pathogenic fungi, we here performed a serial passage experiment in the presence or absence of colony members, which provide social immunity by grooming off infectious spores from exposed individuals. We found specific effects on pathogen diversity, virulence and transmission. Under selection of social immunity, pathogens invested into higher spore production, but spores were less virulent. Notably, they also elicited a lower grooming response in colony members, compared with spores from the individual host selection lines. Chemical spore analysis suggested that the spores from social selection lines escaped the caregivers’ detection by containing lower levels of ergosterol, a key fungal membrane component. Experimental application of chemically pure ergosterol indeed induced sanitary grooming, supporting its role as a microbe-associated cue triggering host social immunity against fungal pathogens. By reducing this detection cue, pathogens were able to evade the otherwise very effective collective disease defences of their social hosts."}],"ddc":["570"],"day":"01","project":[{"_id":"2649B4DE-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Epidemics in ant societies on a chip","grant_number":"771402"},{"_id":"25DAF0B2-B435-11E9-9278-68D0E5697425","name":"Host-Parasite Coevolution","grant_number":"CR-118/3-1"}],"publication":"Nature Ecology and Evolution","external_id":{"pmid":["36732670"],"isi":["000924572800001"]},"author":[{"full_name":"Stock, Miriam","last_name":"Stock","first_name":"Miriam","id":"42462816-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-8214-4758","last_name":"Milutinovic","first_name":"Barbara","id":"2CDC32B8-F248-11E8-B48F-1D18A9856A87","full_name":"Milutinovic, Barbara"},{"last_name":"Hönigsberger","full_name":"Hönigsberger, Michaela","id":"953894f3-25bd-11ec-8556-f70a9d38ef60","first_name":"Michaela"},{"first_name":"Anna V","last_name":"Grasse","id":"406F989C-F248-11E8-B48F-1D18A9856A87","full_name":"Grasse, Anna V"},{"first_name":"Florian","full_name":"Wiesenhofer, Florian","last_name":"Wiesenhofer","id":"39523C54-F248-11E8-B48F-1D18A9856A87"},{"id":"2AC57FAC-F248-11E8-B48F-1D18A9856A87","full_name":"Kampleitner, Niklas","last_name":"Kampleitner","first_name":"Niklas"},{"first_name":"Madhumitha","id":"44BF24D0-F248-11E8-B48F-1D18A9856A87","full_name":"Narasimhan, Madhumitha","last_name":"Narasimhan","orcid":"0000-0002-8600-0671"},{"first_name":"Thomas","full_name":"Schmitt, Thomas","last_name":"Schmitt"},{"last_name":"Cremer","full_name":"Cremer, Sylvia","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","first_name":"Sylvia","orcid":"0000-0002-2193-3868"}],"title":"Pathogen evasion of social immunity","department":[{"_id":"SyCr"},{"_id":"LifeSc"},{"_id":"JiFr"}],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"file":[{"creator":"dernst","checksum":"8244f4650a0e7aeea488d1bcd4a31702","file_id":"14069","date_created":"2023-08-16T11:54:59Z","date_updated":"2023-08-16T11:54:59Z","access_level":"open_access","relation":"main_file","success":1,"file_name":"2023_NatureEcoEvo_Stock.pdf","content_type":"application/pdf","file_size":1600499}]},{"ec_funded":1,"oa_version":"Published Version","issue":"3","publication":"Journal of Chemical Information and Modeling","project":[{"grant_number":"788183","_id":"266A2E9E-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Alpha Shape Theory Extended"},{"name":"Mathematics, Computer Science","call_identifier":"FWF","_id":"268116B8-B435-11E9-9278-68D0E5697425","grant_number":"Z00342"},{"_id":"2561EBF4-B435-11E9-9278-68D0E5697425","name":"Persistence and stability of geometric complexes","call_identifier":"FWF","grant_number":"I02979-N35"}],"abstract":[{"text":"Geometry is crucial in our efforts to comprehend the structures and dynamics of biomolecules. For example, volume, surface area, and integrated mean and Gaussian curvature of the union of balls representing a molecule are used to quantify its interactions with the water surrounding it in the morphometric implicit solvent models. The Alpha Shape theory provides an accurate and reliable method for computing these geometric measures. In this paper, we derive homogeneous formulas for the expressions of these measures and their derivatives with respect to the atomic coordinates, and we provide algorithms that implement them into a new software package, AlphaMol. The only variables in these formulas are the interatomic distances, making them insensitive to translations and rotations. AlphaMol includes a sequential algorithm and a parallel algorithm. In the parallel version, we partition the atoms of the molecule of interest into 3D rectangular blocks, using a kd-tree algorithm. We then apply the sequential algorithm of AlphaMol to each block, augmented by a buffer zone to account for atoms whose ball representations may partially cover the block. The current parallel version of AlphaMol leads to a 20-fold speed-up compared to an independent serial implementation when using 32 processors. For instance, it takes 31 s to compute the geometric measures and derivatives of each atom in a viral capsid with more than 26 million atoms on 32 Intel processors running at 2.7 GHz. The presence of the buffer zones, however, leads to redundant computations, which ultimately limit the impact of using multiple processors.

Molecular and genetic pathways that regulate the selective formation of subsets of presynaptic inputs are largely unknown, despite significant understanding of the general process of synaptogenesis. In this study, we have begun to identify such factors using the spinal monosynaptic stretch reflex circuit as a model system. In this neuronal circuit, Ia proprioceptive afferents establish monosynaptic connections with spinal motor neurons that project to the same muscle (termed homonymous connections) or muscles with related or synergistic function. However, monosynaptic connections are not formed with motor neurons innervating muscles with antagonistic functions. The ETS transcription factor ER81 (also known as ETV1) is expressed by all proprioceptive afferents, but only a small set of motor neuron pools in the lumbar spinal cord of the mouse. Here we use conditional mouse genetic techniques to eliminate Er81 expression selectively from motor neurons. We find that ablation of Er81 in motor neurons reduces synaptic inputs from proprioceptive afferents conveying information from homonymous and synergistic muscles, with no change observed in the connectivity pattern from antagonistic proprioceptive afferents. In summary, these findings suggest a role for ER81 in defined motor neuron pools to control the assembly of specific presynaptic inputs and thereby influence the profile of activation of these motor neurons."}],"day":"01","publication":"Journal of Neurophysiology","issue":"3","oa_version":"None","scopus_import":"1","publication_status":"published","citation":{"short":"D.R.

For example, presynaptic active zone (AZ) nanotopology is resolved in increasing detail. Immunofluorescence imaging of AZ proteins usually relies on epitope preservation using aldehyde-based immunocompetent fixation. Cryofixation techniques, such as high-pressure freezing (HPF) and freeze substitution (FS), are widely used for ultrastructural studies of presynaptic architecture in electron microscopy (EM). HPF/FS demonstrated nearer-to-native preservation of AZ ultrastructure, e.g., by facilitating single filamentous structures. Here, we present a protocol combining the advantages of HPF/FS and direct stochastic optical reconstruction microscopy (dSTORM) to quantify nanotopology of the AZ scaffold protein Bruchpilot (Brp) at neuromuscular junctions (NMJs) of Drosophila melanogaster. Using this standardized model, we tested for preservation of Brp clusters in different FS protocols compared to classical aldehyde fixation. In HPF/FS samples, presynaptic boutons were structurally well preserved with ~22% smaller Brp clusters that allowed quantification of subcluster topology. In summary, we established a standardized near-to-native preparation and immunohistochemistry protocol for SMLM analyses of AZ protein clusters in a defined model synapse. Our protocol could be adapted to study protein arrangements at single-molecule resolution in other intact tissue preparations."}],"day":"21","ddc":["570"],"issue":"3","publication":"International Journal of Molecular Sciences","scopus_import":"1","publication_status":"published","has_accepted_license":"1","article_number":"2128","date_published":"2023-01-21T00:00:00Z","file_date_updated":"2023-02-20T07:09:27Z","citation":{"ista":"Mrestani A, Lichter K, Sirén AL, Heckmann M, Paul MM, Pauli M. 2023.

We demonstrate two distinct applications of XCLP within federated learning. In the first, we use it in a one-shot way to predict labels for unseen test points.

Cell fate transitions occur during embryogenesis in both plants and animals. The epigenomic processes regulating plant embryogenesis remain largely elusive.\r\n\r\nResults: Here, we elucidate chromatin and transcriptomic dynamics during embryogenesis of the most cultivated crop, hexaploid wheat. Time-series analysis reveals stage-specific and proximal–distal distinct chromatin accessibility and dynamics concordant with transcriptome changes. Following fertilization, the remodeling kinetics of H3K4me3, H3K27ac, and H3K27me3 differ from that in mammals, highlighting considerable species-specific epigenomic dynamics during zygotic genome activation. Polycomb repressive complex 2 (PRC2)-mediated H3K27me3 deposition is important for embryo establishment. Later H3K27ac, H3K27me3, and chromatin accessibility undergo dramatic remodeling to establish a permissive chromatin environment facilitating the access of transcription factors to cis-elements for fate patterning. Embryonic maturation is characterized by increasing H3K27me3 and decreasing chromatin accessibility, which likely participates in restricting totipotency while preventing extensive organogenesis. Finally, epigenomic signatures are correlated with biased expression among homeolog triads and divergent expression after polyploidization, revealing an epigenomic contributor to subgenome diversification in an allohexaploid genome.\r\n\r\nConclusions: Collectively, we present an invaluable resource for comparative and mechanistic analysis of the epigenomic regulation of crop embryogenesis."}],"oa_version":"Published Version","article_number":"7","publication_status":"published","extern":"1","scopus_import":"1"},{"doi":"10.1093/plcell/koac346","keyword":["Cell Biology","Plant Science"],"publisher":"Oxford University Press","status":"public","type":"journal_article","date_updated":"2023-10-04T09:48:43Z","intvolume":"        35","article_type":"original","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"12669","pmid":1,"year":"2023","language":[{"iso":"eng"}],"quality_controlled":"1","publication_identifier":{"eissn":["1532-298X"],"issn":["1040-4651"]},"date_created":"2023-02-23T09:14:59Z","volume":35,"month":"06","article_processing_charge":"No","oa":1,"citation":{"short":"P.A.

In the last few years, new sequencing technologies have produced an explosion of new and exciting discoveries in the field but have also given rise to many open questions. Defining these questions, together with old, long-standing gaps in our knowledge, is the spirit of this article. The breadth of topics within RNA biology research is vast, and every aspect of the biology of these molecules contains countless exciting open questions. Here, we asked 12 groups to discuss their most compelling question among some plant RNA biology topics. The following vignettes cover RNA alternative splicing; RNA dynamics; RNA translation; RNA structures; R-loops; epitranscriptomics; long non-coding RNAs; small RNA production and their functions in crops; small RNAs during gametogenesis and in cross-kingdom RNA interference; and RNA-directed DNA methylation. In each section, we will present the current state-of-the-art in plant RNA biology research before asking the questions that will surely motivate future discoveries in the field. We hope this article will spark a debate about the future perspective on RNA biology and provoke novel reflections in the reader."}],"oa_version":"Published Version","author":[{"first_name":"Pablo A","last_name":"Manavella","full_name":"Manavella, Pablo A"},{"full_name":"Godoy Herz, Micaela A","first_name":"Micaela A","last_name":"Godoy Herz"},{"full_name":"Kornblihtt, Alberto R","first_name":"Alberto R","last_name":"Kornblihtt"},{"full_name":"Sorenson, Reed","first_name":"Reed","last_name":"Sorenson"},{"full_name":"Sieburth, Leslie E","first_name":"Leslie E","last_name":"Sieburth"},{"full_name":"Nakaminami, Kentaro","last_name":"Nakaminami","first_name":"Kentaro"},{"full_name":"Seki, Motoaki","last_name":"Seki","first_name":"Motoaki"},{"full_name":"Ding, Yiliang","last_name":"Ding","first_name":"Yiliang"},{"last_name":"Sun","first_name":"Qianwen","full_name":"Sun, Qianwen"},{"full_name":"Kang, Hunseung","last_name":"Kang","first_name":"Hunseung"},{"first_name":"Federico D","full_name":"Ariel, Federico D","last_name":"Ariel"},{"last_name":"Crespi","first_name":"Martin","full_name":"Crespi, Martin"},{"first_name":"Axel J","full_name":"Giudicatti, Axel J","last_name":"Giudicatti"},{"first_name":"Qiang","full_name":"Cai, Qiang","last_name":"Cai"},{"first_name":"Hailing","full_name":"Jin, Hailing","last_name":"Jin"},{"last_name":"Feng","full_name":"Feng, Xiaoqi","id":"e0164712-22ee-11ed-b12a-d80fcdf35958","first_name":"Xiaoqi","orcid":"0000-0002-4008-1234"},{"first_name":"Yijun","full_name":"Qi, Yijun","last_name":"Qi"},{"full_name":"Pikaard, Craig S","first_name":"Craig S","last_name":"Pikaard"}],"external_id":{"pmid":["36477566"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1093/plcell/koac346"}],"department":[{"_id":"XiFe"}],"title":"Beyond transcription: compelling open questions in plant RNA biology"},{"external_id":{"isi":["000944921600001"]},"author":[{"full_name":"Lyons, David B.","last_name":"Lyons","first_name":"David B."},{"first_name":"Amy","full_name":"Briffa, Amy","last_name":"Briffa"},{"full_name":"He, Shengbo","first_name":"Shengbo","last_name":"He"},{"first_name":"Jaemyung","full_name":"Choi, Jaemyung","last_name":"Choi"},{"full_name":"Hollwey, Elizabeth","first_name":"Elizabeth","last_name":"Hollwey","id":"b8c4f54b-e484-11eb-8fdc-a54df64ef6dd"},{"first_name":"Jack","full_name":"Colicchio, Jack","last_name":"Colicchio"},{"last_name":"Anderson","first_name":"Ian","full_name":"Anderson, Ian"},{"first_name":"Xiaoqi","id":"e0164712-22ee-11ed-b12a-d80fcdf35958","full_name":"Feng, Xiaoqi","last_name":"Feng","orcid":"0000-0002-4008-1234"},{"full_name":"Howard, Martin","last_name":"Howard","first_name":"Martin"},{"orcid":"0000-0002-0123-8649","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1","full_name":"Zilberman, Daniel","first_name":"Daniel","last_name":"Zilberman"}],"title":"Extensive de novo activity stabilizes epigenetic inheritance of CG methylation in Arabidopsis transposons","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png"},"department":[{"_id":"DaZi"},{"_id":"XiFe"}],"file":[{"date_updated":"2023-05-11T10:41:42Z","relation":"main_file","access_level":"open_access","date_created":"2023-05-11T10:41:42Z","creator":"kschuh","checksum":"6cbc44fdb18bf18834c9e2a5b9c67123","file_id":"12941","success":1,"file_name":"2023_CellReports_Lyons.pdf","file_size":8401261,"content_type":"application/pdf"}],"scopus_import":"1","corr_author":"1","publication_status":"published","has_accepted_license":"1","article_number":"112132","oa_version":"Published Version","ec_funded":1,"ddc":["580"],"day":"28","abstract":[{"lang":"eng","text":"Cytosine methylation within CG dinucleotides (mCG) can be epigenetically inherited over many generations. Such inheritance is thought to be mediated by a semiconservative mechanism that produces binary present/absent methylation patterns. However, we show here that in Arabidopsis thaliana h1ddm1 mutants, intermediate heterochromatic mCG is stably inherited across many generations and is quantitatively associated with transposon expression. We develop a mathematical model that estimates the rates of semiconservative maintenance failure and de novo methylation at each transposon, demonstrating that mCG can be stably inherited at any level via a dynamic balance of these activities. We find that DRM2 – the core methyltransferase of the RNA-directed DNA methylation pathway – catalyzes most of the heterochromatic de novo mCG, with de novo rates orders of magnitude higher than previously thought, whereas chromomethylases make smaller contributions. Our results demonstrate that stable epigenetic inheritance of mCG in plant heterochromatin is enabled by extensive de novo methylation."}],"project":[{"grant_number":"725746","_id":"62935a00-2b32-11ec-9570-eff30fa39068","call_identifier":"H2020","name":"Quantitative analysis of DNA methylation maintenance with chromatin"}],"issue":"3","publication":"Cell Reports","date_created":"2023-02-23T09:17:44Z","quality_controlled":"1","publication_identifier":{"eissn":["2211-1247"]},"language":[{"iso":"eng"}],"date_published":"2023-03-28T00:00:00Z","file_date_updated":"2023-05-11T10:41:42Z","citation":{"short":"D.B.

Aromatic residues exposed at the fibril surface have a rigid ring axis but undergo ring flips, on a variety of time scales from ns to µs.

The goal of player-max is to maximize the probability to reach a target state against the adversarial player-min. These games lie in NP ∩ coNP and are among the rare combinatorial problems that belong to this complexity class for which the existence of polynomial-time algorithm is a major open question. While randomized sub-exponential time algorithm exists, all known deterministic algorithms require exponential time in the worst-case. An important open question has been whether faster algorithms can be obtained parametrized by the treewidth of the game graph. Even deterministic sub-exponential time algorithm for constant treewidth turn-based stochastic games has remain elusive. In this work our main result is a deterministic algorithm to solve turn-based stochastic games that, given a game with n states, treewidth at most t, and the bit-complexity of the probabilistic transition function log D, has running time O ((tn2 log D)t log n). In particular, our algorithm is quasi-polynomial time for games with constant or poly-logarithmic treewidth."}],"day":"01","publication":"Proceedings of the 2023 Annual ACM-SIAM Symposium on Discrete Algorithms","conference":{"start_date":"2023-01-22","location":"Florence, Italy","name":"SODA: Symposium on Discrete Algorithms","end_date":"2023-01-25"},"date_created":"2023-02-24T12:20:47Z","publication_identifier":{"isbn":["9781611977554"]},"quality_controlled":"1","language":[{"iso":"eng"}],"date_published":"2023-02-01T00:00:00Z","citation":{"apa":"Chatterjee, K., Meggendorfer, T., Saona Urmeneta, R.
