H2B — Brassica oleracea var. botrytis

Summary

BoH2B (BOLND125_C03P013120.1) on cauliflower chromosome 3 encodes a histone H2B family protein with a histone-fold domain and is annotated with structural constituent of chromatin, DNA binding, protein heterodimerization activity, and multiple chromatin-modifying enzyme activities including histone acetylase and deacetylase activities. The gene is associated with nucleosome assembly, meiotic chromosome separation, centromere complex localization, and regulation of shoot apical meristem development. It has been linked to numerous agronomic traits including days to flowering, inflorescence and flower development, leaf and trichome morphology, seed growth and development, root development, stem senescence, and responses to biotic stress, high and low temperature stress, aluminum, and light intensity. Associations also include seed mucilage extrusion, embryo development, and abscisic acid sensitivity. Related genes in other species are linked to centromere organization, haploid production, disease resistance, salt stress response, and thermotolerance.
