COMT — Asparagus officinalis

Summary

A4U43_C04F12730 (COMT) on asparagus chromosome 4 encodes an O-methyltransferase domain-containing protein with caffeate O-methyltransferase, flavone 3'-O-methyltransferase, quercetin 3-O-methyltransferase, acetylserotonin O-methyltransferase, and myricetin 3'-O-methyltransferase activities. The gene is associated with indole glucosinolate metabolism, serotonin metabolism, flavonol biosynthesis, lignin anabolism, and phenylpropanoid anabolism. It has been linked to leaf vein morphology, chlorophyll content, photosynthetic rate, viral disease response, salt stress response, callus formation, guaiacol production, and resistance to root-knot nematode. Additional associations include regulation of anthocyanin metabolism, melatonin anabolism, response to freezing, response to mannitol, phloem transport, regulation of stomatal closure, and seed oilbody biogenesis. The encoded protein localizes to the cytosol, nucleus, plastid, plasmalemma, plasmodesma, plant-type cell wall, and stress granule.
