H4 — Beta vulgaris subsp. vulgaris

Summary

BvH4 (BVRB_5G125930) on sugar beet chromosome Bvchr5_un.sca018 encodes a protein with a histone-fold domain and CENP-T/H4_C region, annotated with multiple chromatin-related molecular functions including histone binding, histone acetylase and deacetylase activities, protein methylase activity, calmodulin binding, calcium ion binding, and protein serine/threonine kinase activity. The gene is associated with nucleosome assembly, epigenetic regulation of gene expression, photoperiodism and flowering, regulation of the vegetative-to-reproductive phase transition, vernalization response, seed maturation, and responses to UV-B and hydrogen peroxide. It is linked to traits including flowering time, bacterial blight disease resistance, shoot branching, leaf and root morphology, chloroplast development, seed growth, stem senescence, brassinosteroid and abscisic acid sensitivity, jasmonic acid content, and salt tolerance.
