Transcriptome analysis of genes regulated by CUP-SHAPED COTYLEDON1 (CUC1) transcription factor in Arabidopsis thaliana

Project description:Samples 1 & 2: Comparison of gene expression between wild type (ecotype Ler) and 35S:CUC1, in which CUP-SHAPED COTYLEDON1, a master regulator of the shoot meristem and boundary establishment, is constitutively expressed under the cauliflower mosaic virus 35S promoter. Samples 3 & 4: Comparison of gene expression between stm-1 (ecotype Ler) and stm-1 35S:CUC1 RNA was isolated from cotyledons of 5-day-old (for Ler vs 35S:CUC1) or 10-day-old (for stm vs 35S:CUC1stm) seedlings. Two independent biological replicates were analyzed for each comparison.

REF6 recognizes specific DNA sequence to regulate H3K27me3 demethylation and organ boundary formation

Project description:RELATIVE OF EARLY FLOWERING 6 (REF6, also known as JMJ12) counteracts Polycomb mediated gene silencing through demethylating histone H3 lysine 27 trimethylation (H3K27me3) in Arabidopsis. Genome-wide analysis has demonstrated that REF6 dependent H3K37me3 demethylation occurs on hundreds of genes. However, how these genes are selectively subjected to H3K27me3 demethylation remains elusive. Here we show that a tandem array of four Cys2-His2 zinc finger domains (C2H2-ZF) at REF6 C-terminus are essential for REF6 function. Mechanistically, we find that C2H2-ZF cluster can directly recognize a specific DNA sequence motif, and is essential for binding of REF6 to its targets. In addition, we demonstrate that CUP-SHAPED COTYLEDON 1 (CUC1) and CUC3 harbor such sequence motif and are direct targets of REF6; while their close homolog, CUC2, without such binding motif is not bound by REF6. Furthermore, REF6 is essential for proper H3K27me3 level at CUC1 locus, CUC1 activation and cotyledon separation. Collectively, our study reveals not only a novel mechanism of H3K27me3 demethylase genome targeting to counteract Polycomb silencing, but also a new function of H3K27me3 demethylation in organ boundary formation.
