COMT — Beta vulgaris subsp. vulgaris

Summary

BvCOMT (BVRB_3G055430) on sugar beet chromosome 3 encodes a methyltransferase with multiple annotated activities, including caffeate O-methyltransferase, flavone 3'-O-methyltransferase, quercetin 3-O-methyltransferase, acetylserotonin O-methyltransferase, myricetin 3'-O-methyltransferase, tyramine N-methyltransferase, and N-methyltransferase activity. The gene is associated with lignin, phenylpropanoid, flavonol, indole glucosinolate, serotonin, melatonin, alkaloid, and phenylethylamine biosynthesis, as well as regulation of anthocyanin metabolism, seed oilbody biogenesis, mucilage production during seed coat development, phloem transport, stomatal closure, and responses to freezing and mannitol. It is linked to leaf vein morphology, viral disease response, cell growth, photosynthetic rate, callus formation, guaiacol production, nematode resistance, and premature senescence. The protein localizes to the nucleus, cytosol, plastid, plasmalemma, plasmodesma, cell wall, and stress granules.
