COMT — Cucumis sativus
Summary
CsCOMT (CSA_4G091880) encodes a caffeate O-methyltransferase (EC 2.1.1.68) belonging to the COMT-like family with a SAM-dependent methyltransferase domain. In cucumber, this gene is associated with lignin, flavonoid, phenylpropanoid, indole glucosinolate, serotonin, and melatonin biosynthesis, as well as regulation of anthocyanin metabolism. It has been linked to responses to freezing, mannitol, and low temperature stress, and to traits including leaf vein morphology, stem diameter, photosynthetic rate, and viral disease response. The gene product localises to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, plant-type cell wall, and stress granule. Studies of related genes in other species connect the COMT family to lignin composition, sinapoyl ester biosynthesis, and tolerance to salt, cold, drought, and Botrytis cinerea.
