H2B — Brassica oleracea var. botrytis
Summary
BoH2B (BOLND125_C09P056050.1_BOLND125_V1) on cauliflower chromosome 9 encodes a histone H2B family protein, a structural constituent of chromatin with DNA binding, protein heterodimerization, and DNA transmethylase activity. It is associated with nucleosome assembly, DNA methylation-dependent heterochromatin assembly, epigenetic regulation of gene expression, and chromatin organization. The gene is linked to responses to salt, wounding, bacteria, and fungi, as well as defence responses. It has been connected to traits including drought tolerance, seed dormancy, auxin content, and plant growth and development. Localization evidence places the product in the nucleus, nucleolus, cytosol, plastid, chloroplast thylakoid and stroma, and plasmodesmata. Studies of related genes in other species link the family to chromatin structure and transformation efficiency.
