PRC2 is a major regulator of gene expression in eukaryotes. It catalyzes the repressive chromatin mark H3K27me3, which leads to very low target genes. NRT2.1, encodes key root nitrate transporter Arabidopsis, targeted by but function on NRT2.1 remains unclear. Here, we demonstrate that directly targets and down-regulates context high transcription, nutritional conditions where this one most highly expressed genes transcriptome. Indeed, mutation CLF, subunit, loss H3K27me3 at results,...
Abstract In Arabidopsis thaliana, root high-affinity nitrate (NO3–) uptake depends mainly on NRT2.1, 2.4, and 2.5, which are repressed by high NO3– supply at the transcript level. For this regulation is due to action of (i) feedback down-regulation N metabolites (ii) repression itself mediated transceptor NRT1.1(NPF6.3). However, for NRT2.4 NRT2.5, signalling pathway(s) remain unknown as do molecular elements involved. Here we show that unlike NRT2.5 not induced in an reductase mutant but...
Plant cells survey and modulate their cell wall to control shape anisotropic growth. Signaling mediated by the plant steroid hormones brassinosteroids (BR) plays a central role in coordinating status growth, alterations BR feedback loop leads life-threatening defects tissue cellular integrity. How of is relayed signaling remains largely unclear. Increasing evidence shows that RAPID ALKALANIZATION FACTORs (RALFs), class secreted peptides, play structural roles at surface. Here we show...
Abstract Polycomb-group (PcG) proteins are major chromatin complexes that regulate gene expression, mainly described as repressors keeping genes in a transcriptionally silent state during development. Recent studies have nonetheless suggested PcG might additional functions, including targeting active or acting independently of expression regulation. However, the reasons for implication and their associated marks on still largely unknown. Here, we report combining mutations CURLY LEAF (CLF)...
Abstract In Arabidopsis thaliana , root high-affinity nitrate (NO 3 - ) uptake depends mainly on NRT2.1, 2.4 and 2.5, which are repressed by high NO supply at the transcript level. For NRT2.1 this regulation is due to action of (i) feedback downregulation N metabolites (ii) repression itself mediated transceptor NRT1.1(NPF6.3). However, for NRT2.4 NRT2.5 signaling pathway(s) remain unknown along with molecular elements involved. Here we show that unlike not induced in a reductase mutant but...
