GBSS1 — Oryza sativa Indica Group
Summary
BGIOSGA024424 (GBSS1, GBSSII) on chromosome 7 of Indica rice encodes a protein with a starch synthase catalytic domain and a starch-binding domain, and has alpha-1,4-glucan glucosyltransferase (NDP-glucose donor) activity (EC 2.4.1.242) and starch synthase activity. It is associated with the regulation of starch biosynthetic process, starch metabolism, and amylose biosynthesis, and localises to the chloroplast starch grain, amyloplast, and chloroplast stroma. The gene is associated with amylose content, grain number, grain yield, spikelet fertility, spikelet sterility, photosynthetic rate, nitrate uptake, leaf composition, and seedling growth and development traits. Related genes in other species are linked to grain weight, grain size, starch content, cold tolerance, drought tolerance, and plant height.
