H4 — Beta vulgaris subsp. vulgaris

Summary

BvH4 (BVRB_3G061320) on sugar beet chromosome 3 encodes a histone H4 protein with a histone-fold domain and CENP-T/H4_C domain, and is annotated with structural constituent of chromatin, DNA binding, histone binding, and multiple chromatin-modifying activities including histone acetylase, deacetylase, and protein methylase activities. The gene is associated with nucleosome assembly, epigenetic regulation of gene expression, photoperiodism and flowering, regulation of the vegetative-to-reproductive phase transition, seed maturation, and responses to UV-B and hydrogen peroxide. It has been linked to traits including flowering time, bacterial blight disease resistance, shoot branching, leaf and root morphology, seed development, chloroplast development, and responses to high and low temperature, salt, and abscisic acid. The protein localizes to the nucleolus, thylakoid, chloroplast envelope, plastid, and plant-type vacuole, and is part of the TIP60 and Sin3-type complexes.
