COMT — Capsicum annuum

Summary

T459_16863 (CaCOMT) on pepper chromosome 6 encodes a caffeic acid 3-O-methyltransferase, a member of the COMT-like and SAM-dependent methyltransferase superfamily. The enzyme exhibits flavone 3'-O-methyltransferase, quercetin 3-O-methyltransferase, caffeate O-methyltransferase, and acetylserotonin O-methyltransferase activities. CaCOMT is associated with indole glucosinolate metabolism, serotonin metabolism, phenylethylamine anabolism, seed oilbody biogenesis, regulation of anthocyanin metabolism, anabolism, melatonin anabolism, flavonol biosynthetic process, mucilage anabolism during seed coat development, sulfur metabolism, positive regulation of protein breakdown, response to mannitol, cadmium transport, coumarin anabolism, indole glucosinolate anabolism, alkaloid anabolism, response to freezing, and lignin anabolism. It localizes to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, cell wall, and stress granules. The gene is associated with leaf vein morphology trait, viral disease response trait, cell growth and development trait, lignin content, photosynthetic rate, callus formation, guaiacol production, resistance to root-knot nematode, glucosinolate biosynthesis, nematode resistance, sinapoyl malate biosynthesis, lignin biosynthesis, syringyl lignin biosynthesis, flavonoid biosynthesis, viral response, transcriptional activation, oxalic acid
