SUS — Brassica oleracea

Summary

BoSUS (BOLC102_C03P012410.1) on cabbage chromosome 3 encodes a sucrose synthase, a member of the Glyco_trans_1 family with sucrose synthase activity. The gene is also annotated for DNA-binding transcription factor activity and cis-regulatory region sequence-specific DNA binding. BoSUS is associated with head development, sucrose and carotene anabolism, chlorophyll anabolism, auxin polar transport, shoot morphogenesis, and responses to anoxia, flooding, sorbitol, mannitol, and glucose. It is linked to grain yield, fruit quality, total soluble sugar content, sucrose content, carotenoid content, seed size, brassinosteroid content, and photoperiod sensitivity. The protein localises to the cytosol, nucleus, and plasmodesmata. Related genes in other species are linked to starch biosynthesis, carbon allocation, anaerobic stress response, chilling tolerance, and floral transition.
