COMT — Beta vulgaris subsp. vulgaris
Summary
BvCOMT (BVRB_3G050960) on sugar beet chromosome 3 encodes a caffeate O-methyltransferase with additional O-methyltransferase activities toward flavones, quercetin, acetylserotonin and myricetin. The protein contains a COMT-like dimerisation domain and a SAM-dependent methyltransferase domain. BvCOMT is associated with lignin, flavonoid, indole glucosinolate, serotonin, melatonin and alkaloid biosynthesis, as well as regulation of anthocyanin metabolism, response to freezing and mannitol, phloem transport, stomatal closure, seed oilbody biogenesis and mucilage deposition during seed coat development. It localises to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, plant-type cell wall and stress granules. The gene has been linked to leaf vein morphology, photosynthetic rate, viral disease response, cell growth, callus formation, guaiacol production, root-knot nematode resistance and alkaline stress tolerance.
