COMT — Brassica oleracea var. botrytis

Summary

BoCOMT, encoded by the cauliflower gene BOLND125_C03P017460.1_BOLND125_V1 on chromosome 3, is a SAM-dependent methyltransferase with caffeate O-methyltransferase, myricetin 3'-O-methyltransferase, quercetin 3-O-methyltransferase, flavone 3'-O-methyltransferase, and acetylserotonin O-methyltransferase activities. It also shows protein dimerization activity and protein phosphorylated amino acid binding. The gene is associated with lignin, phenylpropanoid, flavonol, flavonoid, anthocyanin, serotonin, and melatonin biosynthesis, as well as macroautophagy, response to freezing, seed oilbody biogenesis, mucilage anabolism during seed coat development, leaf vascular tissue pattern formation, and phloem transport. It has been linked to cellulose content, viral disease response, leaf vein morphology, cell growth and development traits, and phenotypes including sinapoyl ester content, lignin composition, and abnormal leaf venation. The protein localises to the cytosol, nucleus, plasmalemma, plasmodesma, plastid, and plant-type cell wall.
