(Submitter supplied) Background. Polycomb Repressive Complex 2 (PRC2) is an essential regulator of gene expression that maintains genes in a repressed state by marking chromatin with trimethylated Histone H3 lysine 27 (H3K27me3). In Arabidopsis, loss of PRC2 function leads to pleiotropic effects on growth and development thought to be due to ectopic expression of seed and embryo-specific genes. While there is some understanding of the mechanisms by which specific genes are targeted by PRC2 in animal systems, it is still not clear how PRC2 is recruited to specific regions of plant genomes.Results. more...

(Submitter supplied) BACKGROUND: Polycomb group complexes PRC1 and PRC2 repress gene expression at the chromatin level in eukaryotes. The classic recruitment model of Polycomb group complexes in which PRC2-mediated H3K27 trimethylation recruits PRC1 for H2A monoubiquitination was recently challenged by data showing that PRC1 activity can also recruit PRC2. However, the prevalence of these two mechanisms is unknown, especially in plants as H2AK121ub marks were examined at only a handful of Polycomb group targets. more...

(Submitter supplied) Using Western blot, we found the level of H3K27me3, but not H3K4me3, H3K9me2 and H3K36me3, was specifically reduced in the tor-es mutant. To gain a genome-wide view of the effects of TOR activity on H3K27me3 distribution, we performed quantitative chromatin immunoprecipitation with an exogenous reference genome (ChIP-Rx) followed by deep-sequencing. We find a global reduction of H3K27me3 occupancy in tor-es, whereas the H3K9me2 level was largely unaffected. more...

(Submitter supplied) CHD3 proteins are ATP-dependent chromatin remodeling factors that are components of diverse multisubunit complexes that can either repress or activate gene expression. In plants, the CHD3 protein PICKLE (PKL) is necessary for repression of seed-specific genes during germination and promotes deposition of the repressive epigenetic mark trimethylation of histone H3 lysine 27 (H3K27me3). It is unknown, however, if PKL acts directly at H3K27me3-enriched loci. more...

(Submitter supplied) The Polycomb repressive complex 2 (PRC2) catalyzes histone H3 Lys27 trimethylation (H3K27me3) to repress gene transcription in multicellular eukaryotes. Despite its importance in gene silencing and cellular differentiation, how PRC2 is recruited to target loci is still not fully understood. Here, we report genome-wide evidence for the recruitment of PRC2 by the transcriptional repressors VIVIPAROUS1/ABI3-LIKE1 (VAL1) and VAL2 in Arabidopsis thaliana. more...

(Submitter supplied) EMBRYONIC FLOWER1 (EMF1) is a plant specific gene crucial to Arabidopsis vegetative development. 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. more...

(Submitter supplied) Callus formation is usually a necessary step in regenerating a new plant from detached plant tissues, and the nature of the callus is similar to that of the root meristem. In this study, we intended to address the molecular basis that directs different plant tissues to form the root-meristem-like callus. We found that leaves, but not roots, of the Polycomb group (PcG) double mutant curly leaf-50 swinger-1 lost the ability to form a callus. more...

(Submitter supplied) In plants, multiple detached tissues are capable of forming a pluripotent cell mass, termed callus, when cultured with appropriate plant hormones. Recent studies demonstrated that callus resembles the tip of a root meristem, even if it is derived from aerial organs. However, the underlying mechanism that guides differentiated organs to form callus is unknown. Here we show that genome-wide reprogramming of histone H3 lysine 27 trimethylation (H3K27me3) is critical in callus formation. more...
