CHS — Oryza sativa Japonica

Summary

OsCHS (OS10G0162856) on rice chromosome 10 encodes a chalcone synthase, a type III polyketide synthase with naringenin-chalcone synthase and bisdemethoxycurcumin synthase activities, and also possesses acyltransferase and protein homodimerization activities. The gene is associated with flavonoid, anthocyanin, and lignin anabolism, as well as polyketide and serotonin anabolism, triterpenoid metabolism, sporopollenin biosynthesis, pollen wall assembly, anther development, and pigmentation. It is linked to traits including flavonoid, anthocyanin, lignin, starch, chlorophyll, and monosaccharide content, grain weight, root length, germination rate, leaf color, turgor pressure, and heat tolerance. The encoded protein localizes to the endoplasmic reticulum. Studies of related genes in other species connect the family to EC 2.3.1.74 and EC 2.3.1.211 activities.
