CHS — Oryza sativa Japonica

Summary

OsCHS (OS10G0168300) in rice encodes a type III polyketide synthase with chalcone/stilbene synthase domains, exhibiting naringenin-chalcone synthase, biphenyl synthase, and bisdemethoxycurcumin synthase activities. The gene is associated with flavonoid, anthocyanin, and lignin anabolism, as well as sporopollenin biosynthesis, pollen exine formation, anther development, and double fertilization. It has been linked to pigmentation, detoxification, serotonin anabolism, triterpenoid metabolism, and polyketide anabolism. Associations with agronomic traits include grain weight, starch content, monosaccharide content, leaf color, chlorophyll content, root length, germination rate, and heat tolerance. Studies of related genes in other species connect the family to EC 2.3.1.74 and related acyltransferase activities.
