UBI10 — Brassica oleracea var. botrytis

Summary

BoUBI10 (UBI10) on cauliflower chromosome 3 encodes a ubiquitin-domain protein. It is associated with thiol-dependent deubiquitinase activity, protein tag function, phytochrome binding, FMN binding, blue light photoreceptor activity, steroid binding, and structural constituent of ribosome. It is linked to modification-dependent proteolysis, deubiquitination, regulation of photosynthesis and proton transport, chloroplast accumulation movement, negative gravitropism, and responses to red/far-red light and water-immersion stress. Associations include traits such as biomass yield, water use efficiency, days to flowering, seedling hypocotyl length, petiole length, leaf vein morphology, starch grain synthesis, viral disease response, and auxin sensitivity. The gene is also connected to phenotypes including dwarfism, reduced fertility, altered root and leaf development, salt tolerance, seed size, and brassinosteroid sensitivity. Related genes in other species are linked to phototropism, blue light sensing, chloroplast migration, stomatal aperture regulation, and freezing tolerance.
