General Information

General Information Comment Organism
evolution the VvAOMT genes cluster results from gene duplication Vitis vinifera
malfunction the AOMT2 gene presents two SNPs associated with methylation level. These mutations, probably leading to a structural change of the AOMT2 protein, significantly affect the enzyme specific catalytic efficiency for the 3'-O-methylation of delphinidin 3-O-beta-D-glucoside Vitis vinifera

physiological function VvAOMT2 expression has no direct regulatory effect on anthocyanin methylation, transcriptional regulation of AOMTs and effects on anthocyanin methylation patterns, overview Vitis vinifera
