General Information

General Information Comment Organism
physiological function steryl glucoside may be specific only for cellulose biosynthesis in cotton fibers because mature fibers contain more than 95% of cellulose Gossypium hirsutum
physiological function steryl glucoside may be specific only for cellulose biosynthesis in cotton fibers because mature fibers contain more than 95% of cellulose. Isozyme GhSGT2 mainly participates in catalyzing glucosylation of membrane sterols Gossypium hirsutum
