CHS — Oryza sativa Japonica

Summary

OsCHS (OS11G0529900) encodes a type III polyketide synthase with chalcone/stilbene synthase and thiolase-like domains, possessing naringenin-chalcone synthase, trihydroxybenzophenone synthase, tetrahydroxybenzophenone synthase, bisdemethoxycurcumin synthase, and acyltransferase activities. The gene is associated with anthocyanin, lignin, serotonin, polyketide, and sporopollenin biosynthesis, as well as malonyl-CoA, benzoyl-CoA, proline, triterpenoid, and starch metabolism, the TCA cycle, pigmentation, pollen exine formation, anther development, double fertilization, detoxification, and biofilm formation. The encoded protein localizes to the endoplasmic reticulum. Trait associations include flavonoid, anthocyanin, chlorophyll, lignin, starch, and monosaccharide content, leaf color, grain weight, root length, germination rate, turgor pressure, and heat tolerance. Studies of related genes in other species link the family to flavonoid biosynthesis.
