CHS — Oryza sativa Japonica

Summary

OsCHS (OS11G0529500) on rice chromosome 11 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, exhibiting naringenin-chalcone synthase and bisdemethoxycurcumin synthase activities, as well as acyltransferase and identical protein binding functions. This gene is associated with serotonin anabolism, triterpenoid metabolism, biofilm formation, proline metabolism, sporopollenin biosynthesis, polyketide anabolism, pigmentation, pollen wall assembly, pollen exine formation, double fertilization, TCA cycle, starch metabolism, syngamy, anther development, detoxification, anthocyanin anabolism, lignin anabolism, and flavonoid anabolism. It has been linked to traits including monosaccharide content, turgor pressure, flavonoid content, leaf color, lignin content, starch content, anthocyanin content, heat tolerance, germination rate, GRWT, root length, chlorophyll content, and grain weight. Studies of related genes in other species connect the family to chalcone synthase activity (EC 2.3.1.74) and curcumin synthase activity (EC 2.3.1.211).
