General Information

General Information Comment Organism
physiological function BGLU10 KO lines accumulate substrate cyanidin 3-O-[2-O-(2-O-(sinapoyl)xylosyl) 6-O-(p-coumaroyl) glucoside] 5-O-[6-O-(malonyl) glucoside]. The expression pattern of BGLU10 and the increase in acyl-glucose-dependent anthocyanin glucosyltransferase activity are consistent with the ratio of accumulating A11 to A9 anthocyanin Arabidopsis thaliana
