Single-residue substitution in histone H3 leads to over-lignification in Arabidopsis

Chromatin changes are at the core of plant development and adaptation, as they constitute a crucial layer of gene expression control. The effects of different chromatin marks have historically been studied through mutations to the protein complexes depositing and removing the marks, which results in…
