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

ABSTRACT:

Background

Histone chaperones modulate chromatin architecture and hence play a pivotal role in epigenetic regulation of gene expression. In contrast to their animal and yeast counterparts, not much is known about plant histone chaperones. To gain insights into their functions in plants, we sought to identify histone chaperones from two model plant species and investigated their phylogeny, domain architecture and transcriptional profiles to establish correlation between their expression patterns and potential role in stress physiology and plant development.

Results

Through comprehensive whole genome analyses of Arabidopsis and rice, we identified twenty-two and twenty-five genes encoding histone chaperones in these plants, respectively. These could be classified into seven di
