COMT — Capsicum annuum

Summary

T459_16866 (CaCOMT) on pepper chromosome 6 encodes a protein with caffeate O-methyltransferase, anthranilate N-methyltransferase, flavone 3'-O-methyltransferase, quercetin 3-O-methyltransferase, acetylserotonin O-methyltransferase, and myricetin 3'-O-methyltransferase activities, and belongs to the COMT-like and SAM-dependent methyltransferase superfamilies. The gene is associated with lignin, flavonol, coumarin, indole glucosinolate, serotonin, and melatonin metabolism, as well as sulfur metabolism, anthocyanin regulation, and responses to freezing and mannitol. It has been linked to leaf vein morphology, viral disease response, lignin content, photosynthetic rate, cell growth, and traits including callus formation, guaiacol production, and resistance to root-knot nematode. The protein localises to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, stress granule, and plant-type cell wall.
