CHS — Oryza sativa Japonica

Summary

OsCHS (OS11G0566800) in rice encodes a type III polyketide synthase with chalcone/stilbene synthase domains, possessing naringenin-chalcone synthase and biphenyl synthase activities, and capable of protein homodimerization. This 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, the TCA cycle, starch metabolism, syngamy, anther development, detoxification, anthocyanin anabolism, lignin anabolism, and flavonoid anabolism. It has been 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 endoplasmic reticulum. Studies of related genes in other species indicate the family is associated with naringenin-chalcone synthase activity (EC 2.3.1.74).
