H4 — Brachypodium distachyon

Summary

BdH4 (BRADI_5G19350V3) on chromosome 5 of Brachypodium distachyon encodes a histone H4 protein, a structural constituent of chromatin that is also associated with histone acetylase, deacetylase, methylase, and DNA-binding activities. The gene is associated with nucleosome assembly, chromatin remodeling, telomeric silencing, and the regulation of phase transitions, including the shift from vegetative to reproductive growth and the upregulation of vernalization response. It is linked to flowering time, photoperiodism, endosperm and seed maturation, somatic embryogenesis, secondary shoot formation, and regeneration. Associations also extend to stress responses, including UV-B, high and low temperature, salt tolerance, and bacterial blight disease resistance, as well as traits such as leaf and root morphology, shoot branching, stem senescence, chloroplast development, and brassinosteroid and abscisic acid sensitivity.
