Histone chaperones in Arabidopsis and rice: genome-wide identification, phylogeny, architecture and transcriptional regulation

Abstract

Taken together, our findings shed light onto the possible evolutionary trajectory of plant histone chaperones and present novel prospects about their physiological roles. Considering that the developmental process and stress response require altered expression of a large array of genes, our results suggest that some plant histone chaperones may serve a regulatory role by controlling the expression of genes associated with these vital processes, possibly via modulating chromatin dynamics at the corresponding genetic loci.
