However, the contradiction between the embryo-lethal phenotypes of the originally described Arabidopsis T-DNA insertional knock-out alleles (abp1-1 and abp1-1s) and the wild type-like phenotypes of other recently described loss-of-function alleles (abp1-c1 and abp1-TD1) questions the biological importance of ABP1 and relevance of the previous genetic studies. Here we show that there is no hidden copy of the ABP1 gene in the Arabidopsis genome but the embryo-lethal phenotypes of abp1-1 and abp1-1s alleles are very similar to the knock-out phenotypes of the neighboring gene, BELAYA SMERT (BSM). Furthermore, the allelic complementation test between bsm and abp1 alleles shows that the embryo-lethality in the abp1-1 and abp1-1s alleles is caused by the off-target disruption of the BSM locus by the T-DNA insertions. This clarifies the controversy of different phenotypes among published abp1 knock-out alleles and asks for reflections on the developmental role of ABP1."}],"title":"Embryo-lethal phenotypes in early abp1 mutants are due to disruption of the neighboring BSM gene","type":"journal_article","publist_id":"5668","pubrep_id":"497","_id":"1509","quality_controlled":"1","article_processing_charge":"No","file_date_updated":"2020-07-14T12:44:59Z","has_accepted_license":"1","volume":4,"status":"public","intvolume":"         4","file":[{"file_name":"IST-2016-497-v1+1_10.12688_f1000research.7143.1_20151102.pdf","relation":"main_file","date_updated":"2020-07-14T12:44:59Z","creator":"system","date_created":"2018-12-12T10:16:12Z","content_type":"application/pdf","file_size":4414248,"file_id":"5198","checksum":"8beae5cbe988e1060265ae7de2ee8306","access_level":"open_access"}],"ec_funded":1,"year":"2015","citation":{"mla":"Michalko, Jaroslav, et al. “Embryo-Lethal Phenotypes in Early Abp1 Mutants Are Due to Disruption of the Neighboring BSM Gene.” <i>F1000 Research </i>, vol. 4, F1000 Research, 2015, doi:<a href=\"https://doi.org/10.12688/f1000research.7143.1\">10.12688/f1000research.7143.1</a>.","apa":"Michalko, J., Lukacisinova, M., Bollenbach, M.

The perturbations are arbitrary continuous maps within L_infty distance r from f for a given r &gt; 0. The main drawback of the approach is that the computability of well groups was shown only when dim K = n or n = 1. Our contribution to the theory of well groups is twofold: on the one hand we improve on the computability issue, but on the other hand we present a range of examples where the well groups are incomplete invariants, that is, fail to capture certain important robust properties of the zero set. For the first part, we identify a computable subgroup of the well group that is obtained by cap product with the pullback of the orientation of R^n by f. In other words, well groups can be algorithmically approximated from below. When f is smooth and dim K &lt; 2n-2, our approximation of the (dim K-n)th well group is exact. For the second part, we find examples of maps f, f' from K to R^n with all well groups isomorphic but whose perturbations have different zero sets. We discuss on a possible replacement of the well groups of vector valued maps by an invariant of a better descriptive power and computability status.

On the one hand, the solution of the classical Heawood problem for graphs on surfaces established that the complete graph K_n embeds in a closed surface M if and only if (n-3)(n-4) is at most 6b_1(M), where b_1(M) is the first Z_2-Betti number of M. On the other hand, Van Kampen and Flores proved that the k-skeleton of the n-dimensional simplex (the higher-dimensional analogue of K_{n+1}) embeds in R^{2k} if and only if n is less or equal to 2k+2. Two decades ago, Kuhnel conjectured that the k-skeleton of the n-simplex embeds in a compact, (k-1)-connected 2k-manifold with kth Z_2-Betti number b_k only if the following generalized Heawood inequality holds: binom{n-k-1}{k+1} is at most binom{2k+1}{k+1} b_k. This is a common generalization of the case of graphs on surfaces as well as the Van Kampen--Flores theorem. In the spirit of Kuhnel's conjecture, we prove that if the k-skeleton of the n-simplex embeds in a 2k-manifold with kth Z_2-Betti number b_k, then n is at most 2b_k binom{2k+2}{k} + 2k + 5. This bound is weaker than the generalized Heawood inequality, but does not require the assumption that M is (k-1)-connected. Our proof uses a result of Volovikov about maps that satisfy a certain homological triviality condition.","lang":"eng"}],"title":"On generalized Heawood inequalities for manifolds: A Van Kampen–Flores-type nonembeddability result","department":[{"_id":"UlWa"}],"related_material":{"record":[{"relation":"later_version","id":"610","status":"public"}]},"alternative_title":["LIPIcs"],"_id":"1511","pubrep_id":"502","quality_controlled":"1","page":"476 - 490","publist_id":"5666","volume":"34 ","has_accepted_license":"1","file_date_updated":"2020-07-14T12:44:59Z","year":"2015","ec_funded":1,"status":"public","file":[{"access_level":"open_access","checksum":"0945811875351796324189312ca29e9e","file_size":636735,"file_id":"4871","file_name":"IST-2016-502-v1+1_42.pdf","relation":"main_file","content_type":"application/pdf","creator":"system","date_updated":"2020-07-14T12:44:59Z","date_created":"2018-12-12T10:11:18Z"}]},{"date_published":"2015-01-01T00:00:00Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"oa_version":"Submitted Version","date_updated":"2026-06-18T18:48:48Z","author":[{"first_name":"Xavier","last_name":"Goaoc","full_name":"Goaoc, Xavier"},{"first_name":"Pavel","last_name":"Paták","full_name":"Paták, Pavel"},{"orcid":"0000-0002-3975-1683","last_name":"Patakova","full_name":"Patakova, Zuzana","first_name":"Zuzana"},{"orcid":"0000-0002-1191-6714","last_name":"Tancer","full_name":"Tancer, Martin","first_name":"Martin"},{"id":"36690CA2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1494-0568","full_name":"Wagner, Uli","last_name":"Wagner","first_name":"Uli"}],"month":"01","oa":1,"ddc":["510"],"doi":"10.4230/LIPIcs.SOCG.2015.507","citation":{"ieee":"X.

Genetic sex determination, the prevalent mode, is generally controlled by a pair of XY sex chromosomes or by an XX/X0 system, but different configurations that include additional sex chromosomes are also present. Although this diversity of sex determining systems has been extensively studied at the cytogenetic level, only the X chromosome of the model pea aphid Acyrthosiphon pisum has been analyzed at the genomic level, and little is known about X chromosome biology in the rest of the order.\r\n\r\nIn this study, we take advantage of published DNA- and RNA-seq data from three additional Hemiptera species to perform a comparative analysis of the gene content and expression of the X chromosome throughout this clade. We find that, despite showing evidence of dosage compensation, the X chromosomes of these species show female-biased expression, and a deficit of male-biased genes, in direct contrast to the pea aphid X. We further detect an excess of shared gene content between these very distant species, suggesting that despite the diversity of sex determining systems, the same chromosomal element is used as the X throughout a large portion of the order.

They are recognized as retrograde messengers that mediate long-term synaptic depression (LTD), but their ability to induce long-term potentiation (LTP) is poorly known. We show that eCBs induce the long-term enhancement of transmitter release at single hippocampal synapses through stimulation of astrocytes when coincident with postsynaptic activity. This LTP requires the coordinated activity of the 3 elements of the tripartite synapse: 1) eCB-evoked astrocyte calcium signal that stimulates glutamate release; 2) postsynaptic nitric oxide production; and 3) activation of protein kinase C and presynaptic group I metabotropic glutamate receptors, whose location at presynaptic sites was confirmed by immunoelectron microscopy. Hence, while eCBs act as retrograde signals to depress homoneuronal synapses, they serve as lateral messengers to induce LTP in distant heteroneuronal synapses through stimulation of astrocytes. Therefore, eCBs can trigger LTP through stimulation of astrocyte-neuron signaling, revealing novel cellular mechanisms of eCB effects on synaptic plasticity."}],"date_created":"2018-12-11T11:52:27Z","publication":"Cerebral Cortex","extern":1,"type":"journal_article","author":[{"last_name":"Gómez Gonzalo","full_name":"Gómez-Gonzalo, Marta","first_name":"Marta"},{"full_name":"Navarrete, Marta","last_name":"Navarrete","first_name":"Marta"},{"last_name":"Perea","full_name":"Perea, Gertrudis","first_name":"Gertrudis"},{"last_name":"Covelo","full_name":"Covelo, Ana","first_name":"Ana"},{"full_name":"Martín-Fernández, Mario","last_name":"Martín Fernández","first_name":"Mario"},{"first_name":"Ryuichi","last_name":"Shigemoto","full_name":"Ryuichi Shigemoto","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Luján, Rafael","last_name":"Luján","first_name":"Rafael"},{"first_name":"Alfonso","full_name":"Araque, Alfonso","last_name":"Araque"}],"status":"public","intvolume":"        25","month":"10","doi":"10.1093/cercor/bhu231","year":"2015","volume":25,"date_published":"2015-10-10T00:00:00Z","date_updated":"2021-01-12T06:51:18Z","issue":"10"},{"issue":"2","date_updated":"2023-02-23T10:02:24Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_published":"2015-01-01T00:00:00Z","volume":41,"author":[{"last_name":"Mansouri","full_name":"Mansouri, Mahnaz","first_name":"Mahnaz"},{"first_name":"Yu","last_name":"Kasugai","full_name":"Kasugai, Yu"},{"first_name":"Yugo","full_name":"Fukazawa, Yugo","last_name":"Fukazawa"},{"last_name":"Bertaso","full_name":"Bertaso, Federica","first_name":"Federica"},{"last_name":"Raynaud","full_name":"Raynaud, Fabrice","first_name":"Fabrice"},{"first_name":"Julie","last_name":"Perroy","full_name":"Perroy, Julie"},{"last_name":"Fagni","full_name":"Fagni, Laurent","first_name":"Laurent"},{"last_name":"Kaufmann","full_name":"Walter Kaufmann","first_name":"Walter","id":"3F99E422-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9735-5315"},{"first_name":"Masahiko","full_name":"Watanabe, Masahiko","last_name":"Watanabe"},{"first_name":"Ryuichi","last_name":"Shigemoto","full_name":"Ryuichi Shigemoto","orcid":"0000-0001-8761-9444","id":"499F3ABC-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Francesco","last_name":"Ferraguti","full_name":"Ferraguti, Francesco"}],"intvolume":"        41","status":"public","doi":"10.1111/ejn.12779","year":"2015","month":"01","citation":{"apa":"Mansouri, M., Kasugai, Y., Fukazawa, Y., Bertaso, F., Raynaud, F., Perroy, J., … Ferraguti, F.

These various forms of plasticity might depend on the subsynaptic arrangement of the receptor in Purkinje cells that can be regulated by protein-protein interactions. This study investigated, by means of the freeze-fracture replica immunogold labelling method, the subcellular localization of mGlu1 receptors in the rodent cerebellum and whether Homer proteins regulate their subsynaptic distribution. We observed a widespread extrasynaptic localization of mGlu1 receptors and confirmed their peri-synaptic enrichment at glutamatergic synapses. Conversely, we detected mGlu1 receptors within the main body of GABAergic synapses onto Purkinje cell dendrites. Although Homer proteins are known to interact with the mGlu1 receptor C-terminus, we could not detect Homer3, the most abundant Homer protein in the cerebellar cortex, at GABAergic synapses by pre-embedding and post-embedding immunoelectron microscopy. We then hypothesized a critical role for Homer proteins in the peri-junctional localization of mGlu1 receptors at glutamatergic synapses. To disrupt Homer-associated protein complexes, mice were tail-vein injected with the membrane-permeable dominant-negative TAT-Homer1a. Freeze-fracture replica immunogold labelling analysis showed no significant alteration in the mGlu1 receptor distribution pattern at parallel fibre-Purkinje cell synapses, suggesting that other scaffolding proteins are involved in the peri-synaptic confinement. The identification of interactors that regulate the subsynaptic localization of the mGlu1 receptor at neurochemically distinct synapses may offer new insight into its trafficking and intracellular signalling."}],"publisher":"Wiley-Blackwell","publication_status":"published","quality_controlled":0,"_id":"1515","publist_id":"5662","page":"157 - 167","day":"01"},{"article_processing_charge":"No","quality_controlled":"1","_id":"15159","page":"489-490","type":"journal_article","title":"Cytosolic BMAL1 moonlights as a translation factor","abstract":[{"text":"It is widely recognized that BMAL1 is an essential subunit of the primary transcription factor that drives rhythmic circadian transcription in the nucleus.

We show here that the cancer/testis antigen PASD1 fulfills this role to suppress circadian rhythms. PASD1 is evolutionarily related to CLOCK and interacts with the CLOCK:BMAL1 complex to repress transcriptional activation. Expression of PASD1 is restricted to germline tissues in healthy individuals but can be induced in cells of somatic origin upon oncogenic transformation. Reducing PASD1 in human cancer cells significantly increases the amplitude of transcriptional oscillations to generate more robust circadian rhythms.

Changes in gene frequencies and genetic associations between loci can be tracked as they respond to a wide variety of evolutionary forces. However, it is often less clear how to decompose these various forces into components that accurately reflect the underlying biology. Here, we present several issues that arise in the definition and interpretation of selection and selection coefficients, focusing on insights gained through the examination of selection coefficients in multilocus notation. Using this notation, we discuss how its flexibility-which allows different biological units to be identified as targets of selection-is reflected in the interpretation of the coefficients that the notation generates. In many situations, it can be difficult to agree on whether loci can be considered to be under &quot;direct&quot; versus &quot;indirect&quot; selection, or to quantify this selection. We present arguments for what the terms direct and indirect selection might best encompass, considering a range of issues, from viability and sexual selection to kin selection. We show how multilocus notation can discriminate between direct and indirect selection, and describe when it can do so.","lang":"eng"}],"department":[{"_id":"NiBa"}],"isi":1,"article_processing_charge":"No","quality_controlled":"1","_id":"1519","pubrep_id":"560","page":"1101 - 1112","publist_id":"5656","issue":"5","has_accepted_license":"1","volume":69,"file_date_updated":"2020-07-14T12:45:00Z","year":"2015","ec_funded":1,"file":[{"file_size":188872,"file_id":"4822","checksum":"fd8d23f476bc194419929b72ca265c02","access_level":"open_access","relation":"main_file","file_name":"IST-2016-560-v1+1_Interpreting_ML_coefficients_11.2.15_App.pdf","creator":"system","date_created":"2018-12-12T10:10:34Z","date_updated":"2020-07-14T12:45:00Z","content_type":"application/pdf"},{"date_updated":"2020-07-14T12:45:00Z","date_created":"2018-12-12T10:10:35Z","creator":"system","content_type":"application/pdf","relation":"main_file","file_name":"IST-2016-560-v1+2_Interpreting_ML_coefficients_11.2.15_mainText.pdf","checksum":"b774911e70044641d556e258efcb52ef","access_level":"open_access","file_id":"4823","file_size":577415}],"intvolume":"        69","status":"public"},{"status":"public","author":[{"first_name":"Gaurav","full_name":"Bharaj, Gaurav","last_name":"Bharaj"},{"first_name":"Stelian","last_name":"Coros","full_name":"Coros, Stelian"},{"last_name":"Thomaszewski","full_name":"Thomaszewski, Bernhard","first_name":"Bernhard"},{"first_name":"James","last_name":"Tompkin","full_name":"Tompkin, James"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","last_name":"Bickel","first_name":"Bernd"},{"last_name":"Pfister","full_name":"Pfister, Hanspeter","first_name":"Hanspeter"}],"year":"2015","doi":"10.1145/2786784.2786803","month":"08","oa_version":"None","date_updated":"2021-01-12T06:51:21Z","date_published":"2015-08-01T00:00:00Z","_id":"1520","conference":{"name":"SCA: ACM SIGGRAPH/Eurographics Symposium on Computer animation","end_date":"2015-08-09","start_date":"2015-08-07","location":"Los Angeles, CA, United States"},"quality_controlled":"1","publisher":"ACM","publication_status":"published","page":"93 - 100","publist_id":"5655","publication_identifier":{"isbn":["978-1-4503-3496-9"]},"language":[{"iso":"eng"}],"scopus_import":1,"day":"01","department":[{"_id":"BeBi"}],"citation":{"apa":"Bharaj, G., Coros, S., Thomaszewski, B., Tompkin, J., Bickel, B., &#38; Pfister, H.

We have developed a theoretical description of genetic regulatory systems in bacteria that explicitly considers the cell division cycle to investigate its impact on gene expression. We calculate the cell-to-cell variations arising from cells being at different stages in the division cycle for unregulated genes and for basic regulatory mechanisms. These variations contribute to the extrinsic noise observed in single-cell experiments, and are most significant for proteins with short lifetimes. Negative autoregulation buffers against variation of protein concentration over the division cycle, but the effect is found to be relatively weak. Stronger buffering is achieved by an increased protein lifetime. Positive autoregulation can strongly amplify such variation if the parameters are set to values that lead to resonance-like behaviour. For cooperative positive autoregulation, the concentration variation over the division cycle diminishes the parameter region of bistability and modulates the switching times between the two stable states. The same effects are seen for a two-gene mutual-repression toggle switch. By contrast, an oscillatory circuit, the repressilator, is only weakly affected by the division cycle.","lang":"eng"}],"type":"journal_article","publist_id":"5641","quality_controlled":"1","_id":"1530","article_processing_charge":"No","volume":12,"issue":"6","intvolume":"        12","status":"public","year":"2015"},{"status":"public","intvolume":"        40","year":"2015","volume":40,"edition":"1","page":"257 - 267","publist_id":"5640","_id":"1531","quality_controlled":"1","article_processing_charge":"No","alternative_title":["Mathematics and Visualization"],"department":[{"_id":"HeEd"}],"abstract":[{"lang":"eng","text":"The Heat Kernel Signature (HKS) is a scalar quantity which is derived from the heat kernel of a given shape. Due to its robustness, isometry invariance, and multiscale nature, it has been successfully applied in many geometric applications. From a more general point of view, the HKS can be considered as a descriptor of the metric of a Riemannian manifold. Given a symmetric positive definite tensor field we may interpret it as the metric of some Riemannian manifold and thereby apply the HKS to visualize and analyze the given tensor data. In this paper, we propose a generalization of this approach that enables the treatment of indefinite tensor fields, like the stress tensor, by interpreting them as a generator of a positive definite tensor field. To investigate the usefulness of this approach we consider the stress tensor from the two-point-load model example and from a mechanical work piece."}],"title":"Visualizing symmetric indefinite 2D tensor fields using The Heat Kernel Signature","type":"book_chapter","author":[{"last_name":"Zobel","full_name":"Zobel, Valentin","first_name":"Valentin"},{"id":"4505473A-F248-11E8-B48F-1D18A9856A87","first_name":"Jan","last_name":"Reininghaus","full_name":"Reininghaus, Jan"},{"last_name":"Hotz","full_name":"Hotz, Ingrid","first_name":"Ingrid"}],"editor":[{"first_name":"Ingrid","last_name":"Hotz","full_name":"Hotz, Ingrid"},{"last_name":"Schultz","full_name":"Schultz, Thomas","first_name":"Thomas"}],"month":"01","doi":"10.1007/978-3-319-15090-1_13","date_published":"2015-01-01T00:00:00Z","oa_version":"None","date_updated":"2022-06-10T09:50:14Z","publication_status":"published","publisher":"Springer","language":[{"iso":"eng"}],"scopus_import":"1","day":"01","publication_identifier":{"isbn":["978-3-319-15089-5"]},"citation":{"mla":"Zobel, Valentin, et al. “Visualizing Symmetric Indefinite 2D Tensor Fields Using The Heat Kernel Signature.” <i>Visualization and Processing of Higher Order Descriptors for Multi-Valued Data</i>, edited by Ingrid Hotz and Thomas Schultz, 1st ed., vol. 40, Springer, 2015, pp. 257–67, doi:<a href=\"https://doi.org/10.1007/978-3-319-15090-1_13\">10.1007/978-3-319-15090-1_13</a>.","short":"V.

Ammonium stress rapidly leads to various metabolic and hormonal imbalances that ultimately inhibit root and shoot growth in many plant species, including Arabidopsis thaliana (L.) Heynh. To identify molecular and genetic factors involved in seedling survival with prolonged exclusive NH4+ nutrition, a transcriptomic analysis with microarrays was used. Substantial transcriptional differences were most pronounced in (NH4)2SO4-grown seedlings, compared with plants grown on KNO3 or NH4NO3. Consistent with previous physiological analyses, major differences in the expression modules of photosynthesis-related genes, an altered mitochondrial metabolism, differential expression of the primary NH4+ assimilation, alteration of transporter gene expression and crucial changes in cell wall biosynthesis were found. A major difference in plant hormone responses, particularly of auxin but not cytokinin, was striking. The activity of the DR5::GUS reporter revealed a dramatically decreased auxin response in (NH4)2SO4-grown primary roots. The impaired root growth on (NH4)2SO4 was partially rescued by exogenous auxin or in specific mutants in the auxin pathway. The data suggest that NH4+-induced nutritional and metabolic imbalances can be partially overcome by elevated auxin levels."}],"title":"Auxin-modulated root growth inhibition in Arabidopsis thaliana seedlings with ammonium as the sole nitrogen source","type":"journal_article","isi":1,"department":[{"_id":"JiFr"}],"month":"03","article_type":"original","doi":"10.1071/FP14171","author":[{"full_name":"Yang, Huaiyu","last_name":"Yang","first_name":"Huaiyu"},{"first_name":"Jenny","full_name":"Von Der Fecht Bartenbach, Jenny","last_name":"Von Der Fecht Bartenbach"},{"last_name":"Friml","full_name":"Friml, Jirí","first_name":"Jirí","id":"4159519E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8302-7596"},{"full_name":"Lohmann, Jan","last_name":"Lohmann","first_name":"Jan"},{"first_name":"Benjamin","last_name":"Neuhäuser","full_name":"Neuhäuser, Benjamin"},{"first_name":"Uwe","full_name":"Ludewig, Uwe","last_name":"Ludewig"}],"date_published":"2015-03-01T00:00:00Z","oa_version":"None","date_updated":"2025-09-23T07:59:44Z","external_id":{"pmid":["32480670"],"isi":["000349635900003"]},"language":[{"iso":"eng"}],"scopus_import":"1","day":"01","publication_identifier":{"issn":["1445-4408"]},"publication_status":"published","publisher":"CSIRO","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","publication":"Functional Plant Biology","date_created":"2018-12-11T11:52:34Z","citation":{"apa":"Yang, H., Von Der Fecht Bartenbach, J., Friml, J., Lohmann, J., Neuhäuser, B., &#38; Ludewig, U.

We exploit top-down guidance, i.e., the coarse localization of the objects and their class labels provided by object detectors. For each detected bounding box, figure-ground segmentation is performed and the final result is achieved by merging the figure-ground segmentations. The main idea of the proposed approach, which is presented in our preliminary work, is to reformulate the figure-ground segmentation problem as sparse reconstruction pursuing the object mask in a nonparametric manner. The latent segmentation mask should be coherent subject to sparse error caused by intra-category diversity; thus, the object mask is inferred by making use of sparse representations over the training set. To handle local spatial deformations, local patch-level masks are also considered and inferred by sparse representations over the spatially nearby patches. The sparse reconstruction coefficients and the latent mask are alternately optimized by applying the Lasso algorithm and the accelerated proximal gradient method. The proposed formulation results in a convex optimization problem; thus, the global optimal solution is achieved. In this paper, we provide theoretical analysis of the convergence and optimality. We also give an extended numerical analysis of the proposed algorithm and a comprehensive comparison with the related semantic segmentation methods on the challenging PASCAL visual object class object segmentation datasets and the Weizmann horse dataset. The experimental results demonstrate that the proposed algorithm achieves a competitive performance when compared with the state of the arts."}],"title":"Segmentation over detection via optimal sparse reconstructions","intvolume":"        25","status":"public","year":"2015","issue":"8","volume":25,"publication_status":"published","publisher":"IEEE","scopus_import":"1","language":[{"iso":"eng"}],"day":"01","citation":{"mla":"Xia, Wei, et al. “Segmentation over Detection via Optimal Sparse Reconstructions.” <i>IEEE Transactions on Circuits and Systems for Video Technology</i>, vol. 25, no. 8, IEEE, 2015, pp. 1295–308, doi:<a href=\"https://doi.org/10.1109/TCSVT.2014.2379972\">10.1109/TCSVT.2014.2379972</a>.","apa":"Xia, W., Domokos, C., Xiong, J., Cheong, L., &#38; Yan, S.

On the one hand, FLP is involved in responses to gravity stimulation in primary roots, whereas on the other, FLP and MYB88 function complementarily in establishing the gravitropic set-point angles of lateral roots.

In the chromaffin cells (CCs) of the adrenal medulla, Cav1.3 is highly expressed and is shown to support most of the pacemaking current that sustains action potential (AP) firings and part of the catecholamine secretion. Cav1.3 forms Ca2+-nanodomains with the fast inactivating BK channels and drives the resting SK currents. These latter set the inter-spike interval duration between consecutive spikes during spontaneous firing and the rate of spike adaptation during sustained depolarizations. Cav1.3 plays also a primary role in the switch from “tonic” to “burst” firing that occurs in mouse CCs when either the availability of voltage-gated Na channels (Nav) is reduced or the β2 subunit featuring the fast inactivating BK channels is deleted. Here, we discuss the functional role of these “neuronlike” firing modes in CCs and how Cav1.3 contributes to them.

Furthermore, strigolactones are involved in the regulation of lateral and adventitious root development, root cell division [5, 6], secondary growth [7], and leaf senescence [8]. Recently, we discovered the strigolactone transporter Petunia axillaris PLEIOTROPIC DRUG RESISTANCE 1 (PaPDR1), which is required for efficient mycorrhizal colonization and inhibition of lateral bud outgrowth [9]. However, how strigolactones are transported through the plant remained unknown. Here we show that PaPDR1 exhibits a cell-type-specific asymmetric localization in different root tissues. In root tips, PaPDR1 is co-expressed with the strigolactone biosynthetic gene DAD1 (CCD8), and it is localized at the apical membrane of root hypodermal cells, presumably mediating the shootward transport of strigolactone. Above the root tip, in the hypodermal passage cells that form gates for the entry of mycorrhizal fungi, PaPDR1 is present in the outer-lateral membrane, compatible with its postulated function as strigolactone exporter from root to soil. Transport studies are in line with our localization studies since (1) a papdr1 mutant displays impaired transport of strigolactones out of the root tip to the shoot as well as into the rhizosphere and (2) DAD1 expression and PIN1/PIN2 levels change in plants deregulated for PDR1 expression, suggestive of variations in endogenous strigolactone contents. In conclusion, our results indicate that the polar localizations of PaPDR1 mediate directional shootward strigolactone transport as well as localized exudation into the soil."}],"type":"journal_article","intvolume":"        25","status":"public","year":"2015","volume":25,"issue":"5"},{"file_date_updated":"2020-07-14T12:45:01Z","issue":"4","volume":160,"has_accepted_license":"1","file":[{"file_name":"IST-2016-484-v1+1_1-s2.0-S0092867415000094-main.pdf","relation":"main_file","creator":"system","date_created":"2018-12-12T10:13:21Z","date_updated":"2020-07-14T12:45:01Z","content_type":"application/pdf","file_size":4362653,"file_id":"5003","access_level":"open_access","checksum":"228d3edf40627d897b3875088a0ac51f"}],"status":"public","intvolume":"       160","year":"2015","department":[{"_id":"CaHe"},{"_id":"MiSi"}],"isi":1,"related_material":{"record":[{"relation":"dissertation_contains","id":"961","status":"public"}]},"type":"journal_article","title":"Cortical contractility triggers a stochastic switch to fast amoeboid cell motility","abstract":[{"text":"3D amoeboid cell migration is central to many developmental and disease-related processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid cell migration mode in early zebrafish embryos, termed stable-bleb migration. Stable-bleb cells display an invariant polarized balloon-like shape with exceptional migration speed and persistence. Progenitor cells can be reversibly transformed into stable-bleb cells irrespective of their primary fate and motile characteristics by increasing myosin II activity through biochemical or mechanical stimuli. Using a combination of theory and experiments, we show that, in stable-bleb cells, cortical contractility fluctuations trigger a stochastic switch into amoeboid motility, and a positive feedback between cortical flows and gradients in contractility maintains stable-bleb cell polarization. We further show that rearward cortical flows drive stable-bleb cell migration in various adhesive and non-adhesive environments, unraveling a highly versatile amoeboid migration phenotype.","lang":"eng"}],"quality_controlled":"1","_id":"1537","pubrep_id":"484","page":"673 - 685","publist_id":"5634","acknowledged_ssus":[{"_id":"SSU"}],"article_processing_charge":"No","external_id":{"isi":["000349208800011"]},"date_updated":"2026-04-08T14:22:39Z","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"oa_version":"Published Version","date_published":"2015-02-12T00:00:00Z","author":[{"first_name":"Verena","last_name":"Ruprecht","full_name":"Ruprecht, Verena","orcid":"0000-0003-4088-8633","id":"4D71A03A-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Stefan","full_name":"Wieser, Stefan","last_name":"Wieser","orcid":"0000-0002-2670-2217","id":"355AA5A0-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Andrew","last_name":"Callan Jones","full_name":"Callan Jones, Andrew"},{"id":"3FE6E4E8-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-5920-9090","full_name":"Smutny, Michael","last_name":"Smutny","first_name":"Michael"},{"id":"4C6E54C6-F248-11E8-B48F-1D18A9856A87","full_name":"Morita, Hitoshi","last_name":"Morita","first_name":"Hitoshi"},{"id":"3BED66BE-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6453-8075","last_name":"Sako","full_name":"Sako, Keisuke","first_name":"Keisuke"},{"orcid":"0000-0003-2676-3367","id":"419EECCC-F248-11E8-B48F-1D18A9856A87","first_name":"Vanessa","last_name":"Barone","full_name":"Barone, Vanessa"},{"full_name":"Ritsch Marte, Monika","last_name":"Ritsch Marte","first_name":"Monika"},{"first_name":"Michael K","full_name":"Sixt, Michael K","last_name":"Sixt","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Voituriez","full_name":"Voituriez, Raphaël","first_name":"Raphaël"},{"id":"39427864-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-0912-4566","last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp J","first_name":"Carl-Philipp J"}],"doi":"10.1016/j.cell.2015.01.008","ddc":["570"],"oa":1,"month":"02","corr_author":"1","citation":{"apa":"Ruprecht, V., Wieser, S., Callan Jones, A., Smutny, M., Morita, H., Sako, K., … Heisenberg, C.-P.
