HAP4 — Brassica oleracea var. botrytis

Summary

BoHAP4, encoded by gene BOLND125_C04P043570.1 on cauliflower chromosome 4, produces a protein with ubiquitin and ribosomal eL40 domains. It is annotated with structural constituent of ribosome, ubiquitin-protein transferase activity, thiol-dependent deubiquitinase, histone methylase activity, and core promoter sequence-specific DNA binding. The gene is associated with regulation of abscisic acid anabolism, stomatal lineage progression, seed morphogenesis, pigmentation, response to freezing, photomorphogenesis, and chromatin modeling. It localizes to the cytosolic large ribosomal subunit, nucleolus, and endosomes. Associations include leaf length, seed longevity, flowering time, pollen fertility, shoot axis branching, root mass density, chloroplast development, and responses to temperature and salinity stress. Phenotypic links connect BoHAP4 to seed size, salt and drought tolerance, cell proliferation, lateral branching, and transposon silencing. Related genes in other species are linked to heat, cold, and temperature stress tolerance, as well as stomatal formation.
