UBI10 — Brassica oleracea var. botrytis

Summary

BoUBI10 (UBI10) on cauliflower chromosome 3 encodes a protein with ubiquitin-like domains and is annotated with a wide range of molecular functions including phytochrome binding, FMN binding, blue light photoreceptor activity, thiol-dependent deubiquitinase activity, protein tag activity, steroid binding, structural constituent of ribosome, protein dimerization activity, transmembrane receptor protein serine/threonine kinase activity, kinase activity, sequence-specific DNA binding, protein kinase activity, transcription cis-regulatory region binding, and identical protein binding. It is associated with modification-dependent proteolysis, deubiquitination, regulation of photosynthesis and proton transport, chloroplast accumulation movement, response to red or far red light, de-etiolation, negative gravitropism, gibberellin biosynthesis, cuticle anabolism, and positive regulation of anthocyanin metabolism. The gene is linked to numerous traits including biomass yield, water use efficiency, days to flowering, seedling hypocotyl length, petal size, leaf vein morphology, starch grain synthesis, viral disease response, and auxin sensitivity, as well as phenotypes such as dwarf plants, reduced fertility, salt tolerance, and brassinosteroid sensitivity.
