CHS — Oryza sativa Japonica

Summary

OsCHS (OS10G0158400) on rice chromosome 10 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, exhibiting naringenin-chalcone synthase, trihydroxystilbene synthase, and bisdemethoxycurcumin synthase activities, as well as acyltransferase and protein homodimerization functions. The gene is associated with flavonoid, anthocyanin, and lignin anabolism, polyketide and serotonin anabolism, triterpenoid metabolism, sporopollenin biosynthesis, pollen wall assembly, anther development, double fertilization, pigmentation, detoxification, and biofilm formation. It is linked to traits including flavonoid, anthocyanin, lignin, starch, chlorophyll, and monosaccharide content, leaf color, grain weight, root length, germination rate, heat tolerance, and turgor pressure. Studies of related genes in other species connect the family to EC 2.3.1.95, 2.3.1.211, and 2.3.1.74 activities.
