COMT — Sorghum bicolor

Summary

SORBI_3007G058600 (SbCOMT) on sorghum chromosome 7 encodes a protein with domains including COMT_dimerisation, COMT_C, COMT-like, WH_DNA-bd_sf, SAM-dependent_MTases_sf, and WH-like_DNA-bd_sf, and has multiple annotated methyltransferase activities, including isoeugenol O-methyltransferase, tricetin O-methyltransferase, quercetin 3-O-methyltransferase, myricetin 3'-O-methyltransferase, flavone 3'-O-methyltransferase, caffeate O-methyltransferase, acetylserotonin O-methyltransferase, O-methyltransferase, SAM-dependent methyltransferase, and methyltransferase activity, as well as ubiquitin ligase substrate adaptor, protein phosphorylated amino acid binding, protein dimerization activity, and transmembrane receptor protein serine/threonine kinase activity. The gene is associated with lignin content and composition, flavonoid and indole glucosinolate biosynthesis, serotonin and melatonin metabolism, and anthocyanin regulation. It has been linked to reproductive period, IAA content, sugar content, leaf vein morphology, viral disease response, cell growth, and traits including callus formation, nematode resistance, oxalic acid resistance, alkaline stress tolerance, and premature leaf senescence. Localisation evidence connects the product to the plant-type cell wall, plasmodesma, plastid, cytosol, nucleus, and stress granules. Studies of related genes in other species
