(Submitter supplied) In plants, environmental stimuli trigger rapid transcriptional reprogramming of relevant gene suites. Regulation occurs down to the local chromatin landscape of the genes, and while epigenetic modifications proceed in a manner dependent on specific organ and tissue contexts, detailed investigations at this level remain limited. To better understand the organ specificity of dynamic chromatin modifications in response to external signals, we treated nitrogen-limited tomato seedlings with a supply of nitrate and measured the genome-wide changes of four histone marks, the permissive histone marks H3K27ac, H3K4me3, and H3K36me3 and repressive mark H3K27me3, in shoots and roots separately.
