H2A.Z, one of the most conserved but enigmatic histone variants that is enriched at the transcriptional start sites of genes, has been implicated in a variety of chromosomal processes. Recently, we reported a genome-wide anticorrelation between H2A.Z and DNA methylation, an epigenetic hallmark of heterochromatin that has also been found in the bodies of active genes in plants and animals. Here, we investigate the basis of this anticorrelation using a novel h2a.z loss-of-function line in Arabidopsis thaliana. Through genome-wide bisulfite sequencing, we demonstrate that loss of H2A.Z in Arabidopsis has only a minor effect on the level or profile of DNA methylation in genes, and we propose that the global anticorrelation between DNA methylation and H2A.Z is primarily caused by the exclusion of H2A.Z from methylated DNA. RNA sequencing and genomic mapping of H2A.Z show that H2A.Z enrichment across gene bodies, rather than at the TSS, is correlated with lower transcription levels and higher measures of gene responsiveness. Loss of H2A.Z causes misregulation of many genes that are disproportionately associated with response to environmental and developmental stimuli. We propose that H2A.Z deposition in gene bodies promotes variability in levels and patterns of gene expression, and that a major function of genic DNA methylation is to exclude H2A.Z from constitutively expressed genes."}],"day":"11","department":[{"_id":"DaZi"}],"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","title":"Deposition of histone variant H2A.Z within gene bodies regulates responsive genes","oa":1,"article_processing_charge":"No","publication_identifier":{"eissn":["1553-7404"],"issn":["1553-7390"]},"doi":"10.1371/journal.pgen.1002988","publisher":"Public Library of Science","extern":"1","date_published":"2012-10-11T00:00:00Z","_id":"9497","quality_controlled":"1","article_number":"e1002988"},{"author":[{"first_name":"Sang Yeol","last_name":"Kim","full_name":"Kim, Sang Yeol"},{"first_name":"Jungeun","last_name":"Lee","full_name":"Lee, Jungeun"},{"full_name":"Eshed-Williams, Leor","last_name":"Eshed-Williams","first_name":"Leor"},{"full_name":"Zilberman, Daniel","id":"6973db13-dd5f-11ea-814e-b3e5455e9ed1","orcid":"0000-0002-0123-8649","first_name":"Daniel","last_name":"Zilberman"},{"full_name":"Sung, Z.

Loss of function mutants in the EMF1 gene mimic the phenotype caused by mutations in Polycomb Group protein (PcG) genes, which encode epigenetic repressors that regulate many aspects of eukaryotic development. In Arabidopsis, Polycomb Repressor Complex 2 (PRC2), made of PcG proteins, catalyzes trimethylation of lysine 27 on histone H3 (H3K27me3) and PRC1-like proteins catalyze H2AK119 ubiquitination. Despite functional similarity to PcG proteins, EMF1 lacks sequence homology with known PcG proteins; thus, its role in the PcG mechanism is unclear. To study the EMF1 functions and its mechanism of action, we performed genome-wide mapping of EMF1 binding and H3K27me3 modification sites in Arabidopsis seedlings. The EMF1 binding pattern is similar to that of H3K27me3 modification on the chromosomal and genic level. ChIPOTLe peak finding and clustering analyses both show that the highly trimethylated genes also have high enrichment levels of EMF1 binding, termed EMF1_K27 genes. EMF1 interacts with regulatory genes, which are silenced to allow vegetative growth, and with genes specifying cell fates during growth and differentiation. H3K27me3 marks not only these genes but also some genes that are involved in endosperm development and maternal effects. Transcriptome analysis, coupled with the H3K27me3 pattern, of EMF1_K27 genes in emf1 and PRC2 mutants showed that EMF1 represses gene activities via diverse mechanisms and plays a novel role in the PcG mechanism.","lang":"eng"}],"language":[{"iso":"eng"}],"citation":{"ista":"Kim SY, Lee J, Eshed-Williams L, Zilberman D, Sung ZR. 2012.

Studies in plants and animals have shown that the genome-wide distributions of H2A.Z and DNA methylation are strikingly anticorrelated. Furthermore, we and other investigators have shown that this relationship is likely to be the result of an ancient but unknown mechanism by which DNA methylation prevents the incorporation of H2A.Z.

An intriguing yet little understood phenomenon is that social contact to pathogen-exposed individuals reduces susceptibility of previously naive nestmates to this pathogen. We tested whether such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium anisopliae is based on active upregulation of the immune system of nestmates following contact to an infectious individual or passive protection via transfer of immune effectors among group members—that is, active versus passive immunisation. We found no evidence for involvement of passive immunisation via transfer of antimicrobials among colony members. Instead, intensive allogrooming behaviour between naive and pathogen-exposed ants before fungal conidia firmly attached to their cuticle suggested passage of the pathogen from the exposed individuals to their nestmates. By tracing fluorescence-labelled conidia we indeed detected frequent pathogen transfer to the nestmates, where they caused low-level infections as revealed by growth of small numbers of fungal colony forming units from their dissected body content. These infections rarely led to death, but instead promoted an enhanced ability to inhibit fungal growth and an active upregulation of immune genes involved in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there was no upregulation of the gene cathepsin L, which is associated with antibacterial and antiviral defences, and we found no increased antibacterial activity of nestmates of fungus-exposed ants. This indicates that social immunisation after fungal exposure is specific, similar to recent findings for individual-level immune priming in invertebrates. Epidemiological modeling further suggests that active social immunisation is adaptive, as it leads to faster elimination of the disease and lower death rates than passive immunisation. Interestingly, humans have also utilised the protective effect of low-level infections to fight smallpox by intentional transfer of low pathogen doses (“variolation” or “inoculation”)."}],"date_published":"2012-09-27T00:00:00Z","_id":"9755","citation":{"short":"M.

Sanitary behaviour, such as pathogen avoidance and removal, acts as a first line of defence to prevent infection [1] before activation of the physiological immune system. Insect societies have evolved a wide range of collective hygiene measures and intensive health care towards pathogen-exposed group members [2]. One of the most common behaviours is allogrooming, in which nestmates remove infectious particles from the body surfaces of exposed individuals [3]. Here we show that, in invasive garden ants, grooming of fungus-exposed brood is effective beyond the sheer mechanical removal of fungal conidiospores as it also includes chemical disinfection through the application of poison produced by the ants themselves. Formic acid is the main active component of the poison. It inhibits fungal growth of conidiospores remaining on the brood surface after grooming and also those collected in the mouth of the grooming ant. This dual function is achieved by uptake of the poison droplet into the mouth through acidopore self-grooming and subsequent application onto the infectious brood via brood grooming. This extraordinary behaviour extends current understanding of grooming and the establishment of social immunity in insect societies.","lang":"eng"}],"doi":"10.5061/dryad.61649","publisher":"Dryad","date_updated":"2025-09-30T08:15:49Z","article_processing_charge":"No","author":[{"id":"35A7A418-F248-11E8-B48F-1D18A9856A87","full_name":"Tragust, Simon","first_name":"Simon","last_name":"Tragust"},{"full_name":"Mitteregger, Barbara","id":"479DDAAC-E9CD-11E9-9B5F-82450873F7A1","first_name":"Barbara","last_name":"Mitteregger"},{"id":"419EECCC-F248-11E8-B48F-1D18A9856A87","full_name":"Barone, Vanessa","first_name":"Vanessa","orcid":"0000-0003-2676-3367","last_name":"Barone"},{"id":"46528076-F248-11E8-B48F-1D18A9856A87","full_name":"Konrad, Matthias","first_name":"Matthias","last_name":"Konrad"},{"first_name":"Line V","orcid":"0000-0003-1832-8883","last_name":"Ugelvig","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87","full_name":"Ugelvig, Line V"},{"id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","full_name":"Cremer, Sylvia","first_name":"Sylvia","orcid":"0000-0002-2193-3868","last_name":"Cremer"}],"related_material":{"record":[{"status":"public","id":"2926","relation":"used_in_publication"}]},"day":"14","month":"12","department":[{"_id":"SyCr"}],"user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","year":"2012","title":"Data from: Ants disinfect fungus-exposed brood by oral uptake and spread of their poison","oa":1},{"related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"2944"}]},"day":"14","department":[{"_id":"NiBa"}],"month":"11","year":"2012","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","oa":1,"title":"Data from: Approximate Bayesian computation for modular inference problems with many parameters: the example of migration rates","article_processing_charge":"No","author":[{"last_name":"Aeschbacher","first_name":"Simon","id":"2D35326E-F248-11E8-B48F-1D18A9856A87","full_name":"Aeschbacher, Simon"},{"last_name":"Futschik","first_name":"Andreas","full_name":"Futschik, Andreas"},{"last_name":"Beaumont","first_name":"Mark","full_name":"Beaumont, Mark"}],"doi":"10.5061/dryad.274b1","publisher":"Dryad","date_updated":"2025-09-29T13:25:35Z","date_published":"2012-11-14T00:00:00Z","_id":"9758","citation":{"chicago":"Aeschbacher, Simon, Andreas Futschik, and Mark Beaumont. “Data from: Approximate Bayesian Computation for Modular Inference Problems with Many Parameters: The Example of Migration Rates.” Dryad, 2012. <a href=\"https://doi.org/10.5061/dryad.274b1\">https://doi.org/10.5061/dryad.274b1</a>.","apa":"Aeschbacher, S., Futschik, A., &#38; Beaumont, M.

The approach is not limited to migration, but generally of interest for inference problems with multiple parameters and a modular structure (e.g. independent sets of demes or loci). We condition on a known, but complex demographic model of a spatially subdivided population, motivated by the reintroduction of Alpine ibex (Capra ibex) into Switzerland. In the first step, the global parameters ancestral mutation rate and male mating skew have been estimated for the whole population in Aeschbacher et al. (Genetics 2012; 192: 1027). In the second step, we estimate in this study the migration rates independently for clusters of demes putatively connected by migration. For large clusters (many migration rates), ABC faces the problem of too many summary statistics. We therefore assess by simulation if estimation per pair of demes is a valid alternative. We find that the trade-off between reduced dimensionality for the pairwise estimation on the one hand and lower accuracy due to the assumption of pairwise independence on the other depends on the number of migration rates to be inferred: the accuracy of the pairwise approach increases with the number of parameters, relative to the joint estimation approach. To distinguish between low and zero migration, we perform ABC-type model comparison between a model with migration and one without. Applying the approach to microsatellite data from Alpine ibex, we find no evidence for substantial gene flow via migration, except for one pair of demes in one direction."}],"status":"public"},{"date_updated":"2026-06-18T19:08:51Z","ddc":["500"],"OA_place":"publisher","intvolume":"         8","abstract":[{"text":"First we note that the best polynomial approximation to vertical bar x vertical bar on the set, which consists of an interval on the positive half-axis and a point on the negative half-axis, can be given by means of the classical Chebyshev polynomials.

Specifically, we focus on a non-coherent setup employing a double-differential encoding scheme at the source node and a single differential demodulation at the relay and destination. The log-likelihood ratio based decision rule is derived at the destination node. A semi-analytical power allocation strategy is presented by evaluating a closed-form expression for the effective signal to noise ratio (SNR) at the destination, which is maximized by exhaustive search. Numerical simulations show that the proposed system outperforms both the direct transmission with single differential encoding and the non-cooperative multi-hop approach in different scenarios.","lang":"eng"}],"type":"conference","oa_version":"None","publication":"2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)","date_created":"2019-07-31T09:14:48Z","publisher":"IEEE","doi":"10.1109/icassp.2012.6288524","date_updated":"2021-01-12T08:08:49Z","conference":{"name":"ICASSP: International Conference on Acoustics, Speech and Signal Processing","end_date":"2012-03-30","location":"Kyoto, Japan","start_date":"2012-03-25"},"extern":"1","page":"2905-2908","publication_identifier":{"issn":["1520-6149"]},"author":[{"last_name":"Mondelli","first_name":"Marco","orcid":"0000-0002-3242-7020","id":"27EB676C-8706-11E9-9510-7717E6697425","full_name":"Mondelli, Marco"},{"full_name":"Zhou, Qi","first_name":"Qi","last_name":"Zhou"},{"first_name":"Xiaoli","last_name":"Ma","full_name":"Ma, Xiaoli"},{"last_name":"Lottici","first_name":"Vincenzo","full_name":"Lottici, Vincenzo"}],"month":"07","day":"31","title":"A cooperative approach for amplify-and-forward differential transmitted reference IR-UWB relay systems","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2012"},{"date_updated":"2021-01-12T08:11:43Z","intvolume":"        47","extern":"1","publisher":"Springer Nature","doi":"10.1007/s10853-012-6463-6","status":"public","abstract":[{"text":"The Seebeck coefficients, electrical resistivities, total thermal conductivities, and magnetization are reported for temperatures between 5 and 350 K for n-type Bi0.88Sb0.12 nano-composite alloys made by Ho-doping at the 0, 1, and 3 % atomic levels.

However, the stability of carbon and the effect of carbon on electrolyte decomposition in such cells are complex and depend on the hydrophobicity/hydrophilicity of the carbon surface. Analyzing carbon cathodes, cycled in Li–O2 cells between 2 and 4 V, using acid treatment and Fenton’s reagent, and combined with differential electrochemical mass spectrometry and FTIR, demonstrates the following: Carbon is relatively stable below 3.5 V (vs Li/Li+) on discharge or charge, especially so for hydrophobic carbon, but is unstable on charging above 3.5 V (in the presence of Li2O2), oxidatively decomposing to form Li2CO3. Direct chemical reaction with Li2O2 accounts for only a small proportion of the total carbon decomposition on cycling. Carbon promotes electrolyte decomposition during discharge and charge in a Li–O2 cell, giving rise to Li2CO3 and Li carboxylates (DMSO and tetraglyme electrolytes). The Li2CO3 and Li carboxylates present at the end of discharge and those that form on charge result in polarization on the subsequent charge. Li2CO3 (derived from carbon and from the electrolyte) as well as the Li carboxylates (derived from the electrolyte) decompose and form on charging. Oxidation of Li2CO3 on charging to ∼4 V is incomplete; Li2CO3 accumulates on cycling resulting in electrode passivation and capacity fading. Hydrophilic carbon is less stable and more catalytically active toward electrolyte decomposition than carbon with a hydrophobic surface. If the Li–O2 cell could be charged at or below 3.5 V, then carbon may be relatively stable, however, its ability to promote electrolyte decomposition, presenting problems for its use in a practical Li–O2 battery. The results emphasize that stable cycling of Li2O2 at the cathode in a Li–O2 cell depends on the synergy between electrolyte and electrode; the stability of the electrode and the electrolyte cannot be considered in isolation."}],"type":"journal_article","date_created":"2020-01-15T12:18:57Z","oa_version":"None","publication":"Journal of the American Chemical Society","month":"11","volume":135,"day":"28","issue":"1","title":"The carbon electrode in nonaqueous Li–O2 cells","publication_status":"published","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2012","page":"494-500","publication_identifier":{"issn":["0002-7863","1520-5126"]},"article_processing_charge":"No","author":[{"last_name":"Ottakam Thotiyl","first_name":"Muhammed M.","full_name":"Ottakam Thotiyl, Muhammed M."},{"last_name":"Freunberger","first_name":"Stefan Alexander","orcid":"0000-0003-2902-5319","id":"A8CA28E6-CE23-11E9-AD2D-EC27E6697425","full_name":"Freunberger, Stefan Alexander"},{"last_name":"Peng","first_name":"Zhangquan","full_name":"Peng, Zhangquan"},{"last_name":"Bruce","first_name":"Peter G.","full_name":"Bruce, Peter G."}]},{"date_updated":"2021-01-12T08:12:56Z","extern":"1","intvolume":"        51","publisher":"Wiley","doi":"10.1002/anie.201201429","abstract":[{"text":"Energy‐storage technologies, including electrical double‐layer capacitors and rechargeable batteries, have attracted significant attention for applications in portable electronic devices, electric vehicles, bulk electricity storage at power stations, and “load leveling” of renewable sources, such as solar energy and wind power.

This directional transport is largely orchestrated by a complex interaction of specific influx and efflux carriers that mediate the auxin flow into and out of cells, respectively. Besides these transport proteins, plant-specific polyphenolic compounds knownasflavonols have beenshownto act as endogenous regulators of auxin transport. However, only limited information is available on how flavonol synthesis is developmentally regulated. Using reduction-of-function and overexpression approaches in parallel, we demonstrate that the WRKY23 transcription factor is needed for proper root growth and development by stimulating the local biosynthesis of flavonols. The expression of WRKY23 itself is controlled by auxin through the AUXIN RESPONSE FACTOR 7 (ARF7) and ARF19 transcriptional response pathway. Our results suggest a model in which WRKY23 is part of a transcriptional feedback loop of auxin on its own transport through local regulation of flavonol biosynthesis.","lang":"eng"}],"type":"journal_article","publist_id":"3595","date_created":"2018-12-11T12:01:24Z","publication":"PNAS","citation":{"chicago":"Grunewald, Wim, Ive De Smet, Daniel Lewis, Christian Löfke, Leentje Jansen, Geert Goeminne, Robin Vanden Bossche, et al. “Transcription Factor WRKY23 Assists Auxin Distribution Patterns during Arabidopsis Root Development through Local Control on Flavonol Biosynthesis.” <i>PNAS</i>.

Known plant signaling molecules include phytohormones and hormone peptides. Although both classes can be implicated in the same developmental processes, little is known about the interplay between phytohormone action and peptide signaling within the cellular microenvironment. We show that genes coding for small secretory peptides, designated GOLVEN (GLV), modulate the distribution of the phytohormone auxin. The deregulation of the GLV function impairs the formation of auxin gradients and alters the reorientation of shoots and roots after a gravity stimulus. Specifically, the GLV signal modulates the trafficking dynamics of the auxin efflux carrier PIN-FORMED2 involved in root tropic responses and meristem organization. Our work links the local action of secretory peptides with phytohormone transport. Root growth factor (RGF) or GOLVEN (GLV) secreted peptides have previously been implicated in meristem regulation. Whitford et al. now show that RGF/GLV peptides induce rapid relocalization of the auxin efflux regulator PIN2, regulate auxin gradients, and modulate auxin-dependent root responses to specific stimuli.","lang":"eng"}],"type":"journal_article","publication":"Developmental Cell","date_created":"2018-12-11T12:01:25Z","publist_id":"3594"},{"citation":{"ista":"Nagawa S, Xu T, Lin D, Dhonukshe P, Zhang X, Friml J, Scheres B, Fu Y, Yang Z. 2012.

In plants, the asymmetrical distribution of the PIN-FORMED (PIN) proteins involved in the cellular efflux of the quintessential phytohormone auxin plays a central role in developmental patterning, morphogenesis, and differential growth. Recently we showed that auxin promotes cell interdigitation by activating the Rho family ROP GTPases in leaf epidermal pavement cells. Here we found that auxin activation of the ROP2 signaling pathway regulates the asymmetric distribution of PIN1 by inhibiting its endocytosis. ROP2 inhibits PIN1 endocytosis via the accumulation of cortical actin microfilaments induced by the ROP2 effector protein RIC4. Our findings suggest a link between the developmental auxin signal and polar PIN1 distribution via Rho-dependent cytoskeletal reorganization and reveal the conservation of a design principle for cell polarization that is based on Rho GTPase-mediated inhibition of endocytosis.","lang":"eng"}],"status":"public","publication":"PLoS Biology","date_created":"2018-12-11T12:01:25Z","publist_id":"3593","type":"journal_article","publisher":"Public Library of Science","doi":"10.1371/journal.pbio.1001299","date_updated":"2021-01-12T07:41:06Z","extern":1,"intvolume":"        10","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"author":[{"full_name":"Nagawa, Shingo","first_name":"Shingo","last_name":"Nagawa"},{"last_name":"Xu","first_name":"Tongda","full_name":"Xu, Tongda"},{"first_name":"Deshu","last_name":"Lin","full_name":"Lin, Deshu"},{"first_name":"Pankaj","last_name":"Dhonukshe","full_name":"Dhonukshe, Pankaj"},{"first_name":"Xingxing","last_name":"Zhang","full_name":"Zhang, Xingxing"},{"full_name":"Jirí Friml","id":"4159519E-F248-11E8-B48F-1D18A9856A87","last_name":"Friml","orcid":"0000-0002-8302-7596","first_name":"Jirí"},{"full_name":"Scheres, Ben","first_name":"Ben","last_name":"Scheres"},{"full_name":"Fu, Ying","last_name":"Fu","first_name":"Ying"},{"last_name":"Yang","first_name":"Zhenbiao","full_name":"Yang, Zhenbiao"}],"month":"04","issue":"4","day":"01","volume":10,"publication_status":"published","title":"ROP GTPase-dependent actin microfilaments promote PIN1 polarization by localized inhibition of clathrin-dependent endocytosis","year":"2012"}]
