UBQ10 — Cicer arietinum

Summary

UBQ10 (UBI10) on chickpea chromosome 4 encodes a ubiquitin domain-containing protein with protease and thiol-dependent deubiquitinase activity, and is also annotated for phytochrome binding, blue light photoreceptor activity, and structural ribosome constituent roles. The gene is associated with modification-dependent proteolysis, deubiquitination, regulation of photomorphogenesis, chloroplast accumulation movement, and responses to red or far-red light and water-immersion stress. It is linked to auxin signalling pathways, seed development, and regulation of seed size. Traits associated with UBQ10 include biomass yield, water use efficiency, days to flowering, phototropism, seedling hypocotyl length, root mass density, stomatal resistance, auxin and brassinosteroid sensitivity, and viral disease response. Studies of related genes in other species link the family to seed size, salt and drought tolerance, cell proliferation, and apical dominance.
