H4 — Brachypodium distachyon

Summary

BdH4 (BRADI_4G30960V3) on chromosome 4 of Brachypodium distachyon encodes a histone H4 protein, a core structural constituent of chromatin that also possesses methyl-CpG binding, protein methylase, histone acetylase, histone deacetylase, and histone binding activities. The gene is associated with nucleosome assembly, chromatin modeling, telomeric silencing, and the regulation of flowering time, including photoperiodism and the transition from vegetative to reproductive phase. It has been linked to seed maturation, endosperm development, somatic embryogenesis, secondary shoot formation, regeneration, and response to UV-B. Associations with agronomic traits include bacterial blight disease resistance, stem senescence, shoot axis branching, flowering time, seed growth and development, leaf morphology, root development, and high and low temperature stress response, as well as abscisic acid sensitivity.
