CHS — Oryza sativa Japonica

Summary

OsCHS (OS05G0496300) on rice chromosome 5 encodes a protein with chalcone/stilbene synthase N-terminal domain, polyketide synthase type-III domain, and thiolase-like domain, and has naringenin-chalcone synthase activity, bisdemethoxycurcumin synthase activity, acyltransferase activity, protein homodimerization activity, and identical protein binding. The 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. Associations with traits include 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 endoplasmic reticulum. Studies of related genes in other species link the family to EC 2.3.1.74 and EC 2.3.1.211 activities.
