COMT — Capsicum annuum

Summary

CaCOMT (T459_09716) on pepper chromosome 3 encodes a SAM-dependent O-methyltransferase with flavone 3'-O-methyltransferase, quercetin 3-O-methyltransferase, caffeate O-methyltransferase, and acetylserotonin O-methyltransferase activities. The gene is associated with lignin, flavonol, anthocyanin, indole glucosinolate, serotonin, and melatonin metabolism, as well as sulfur metabolism, seed oilbody biogenesis, mucilage anabolism during seed coat development, phloem transport, regulation of stomatal closure, and responses to freezing and mannitol. It is linked to leaf vein morphology, lignin content, photosynthetic rate, viral disease response, cell growth and development traits, and phenotypes including callus formation, guaiacol production, and resistance to root-knot nematode. The product localises to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, plant-type cell wall, and stress granules.
