Genome-wide profiling of SWI/SNF chromatin remodeler BRAHMA and Histone H3 lysine demethyalse Relative of Early Flowering 6 (REF6) in Arabidopsis

Project description:BRAHMA (BRM) is a conserved SWI/SNF-type chromatin remodeling ATPase implicated in many key nuclear events. Histone H3 Lysine 27 (H3K27) demethylases specifically remove the repressive histone mark, trimethylation of H3K27 (H3K27me3). Both proteins are thought to play active roles in regulating gene activities at the chromatin level, but their genome-wide coordination remains to be determined. In Arabidopsis thaliana, RELATIVE OF EARLY FLOWERING 6 (REF6, also known as JMJ12) is the first identified plant H3K27 demethylase. Here, genome-wide analyses revealed that REF6 targets to thousands of genes across the Arabidopsis genome and co-localizes with BRM at more than 1,000 genes, many of which are genes involved in response to various stimuli, especially plant hormones. Loss of REF6 activity results in decreased BRM occupancy at hundreds of BRM-REF6 co-targets, indicating that REF6 is required for the recruitment of BRM to chromatin. Further, REF6 targets to genomic loci that contains the CTCTGTTT motif in vivo

Differential gene expression in ref6-1

Project description:We demonstrate that REF6/JMJ12 (RELATIVE OF EARLY FLOWERING 6/Jumonji domain-containing protein 12) is an H3K27me3 and H3K27me2 demethylase. Plants overexpressing REF6/JMJ12 resemble mutants defective in H3K27me3-mediated gene silencing. Genetic interaction tests indicate that REF6/JMJ12 acts downstream of H3K27me3 methyltransferases. Moreover, loss of REF6/JMJ12 leads to ectopic and increased H3K27me3 and decreased mRNA expression of a large spectrum of genes involved in development and hormone responses to stimuli. Expression array to identify differentially expressed genes in ref6-1. For genome-wide expression analysis of ref6/jmj12, two replicates of Col and ref6/jmj12 samples (RNA from 10-day-old whole seedlings on MS plates in long day conditions at 23 degrees) were analyzed on an Affymetrix ATH1 chip by an Affymetrix service facility (CapitalBio Corporation) according to the manufacturer's protocols. Genes showing a 20.6-fold change with a q-value < 0.05 were considered as differentially expressed.
