CHS — Oryza sativa Japonica

Summary

OsCHS (OS10G0484800) encodes a type III polyketide synthase with chalcone/stilbene synthase domains, exhibiting naringenin-chalcone synthase, trihydroxystilbene synthase, and tetraketide alpha-pyrone synthase activities. In rice, this gene is associated with sporopollenin biosynthesis, pollen wall assembly, and male fertility, as well as anthocyanin, flavonoid, lignin, serotonin, and triterpenoid metabolism. It has been linked to pigmentation, detoxification, biofilm formation, and the TCA cycle, starch metabolism, and proline metabolism. Associations with agronomic traits include grain weight, starch content, monosaccharide content, chlorophyll content, leaf color, root length, germination rate, heat tolerance, and pollen fertility restoration. The protein localizes to the cytoplasm and endoplasmic reticulum. Studies of related genes in other species link the family to stilbene synthase and chalcone synthase activities.
