CHS — Oryza sativa Japonica

Summary

OsCHS (OS11G0529800) encodes a type III polyketide synthase with chalcone/stilbene synthase domains, possessing naringenin-chalcone synthase and bisdemethoxycurcumin synthase activities, as well as acyltransferase and identical protein binding functions. This rice 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 is linked to traits including monosaccharide content, turgor pressure, flavonoid content, leaf color, lignin content, starch content, anthocyanin content, heat tolerance, germination rate, grain weight, root length, and chlorophyll content. The encoded protein localizes to the cytoplasm. Studies of related genes in other species connect the family to EC 2.3.1.74, 2.3.1.211, and 2.3.1.218 activities.
