COMT — Brassica oleracea

Summary

BoCOMT, encoded by the gene BOLC102_C03P018070.1_BOLC102_V1 on cabbage chromosome 3, is a member of the SAM-dependent methyltransferase superfamily and exhibits caffeate O-methyltransferase, myricetin 3'-O-methyltransferase, quercetin 3-O-methyltransferase, flavone 3'-O-methyltransferase, and acetylserotonin O-methyltransferase activities. This gene is associated with lignin, flavonoid, and phenylpropanoid anabolism, as well as serotonin metabolism, melatonin anabolism, chlorophyll breakdown, and regulation of anthocyanin metabolism. It has been linked to traits including lignin content, flavonoid content, leaf vein morphology, viral disease response, and cell growth and development. Associations with response to freezing, response to mannitol, regulation of stomatal closure, phloem transport, and seed oilbody biogenesis have also been observed. The encoded protein localizes to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, and plant-type cell wall.
