CHS — Oryza sativa Indica Group

Summary

BGIOSGA032565 (symbol CHS, OiCHS) on chromosome 10 of Indica rice encodes a chalcone synthase, a type III polyketide synthase with chalcone/stilbene synthase domains. The enzyme exhibits naringenin-chalcone synthase, trihydroxystilbene synthase, and bisdemethoxycurcumin synthase activities, along with acyltransferase and homodimerization functions. This gene is associated with regulation of flavonoid anabolism, polyketide anabolism, S phase, metabolic burst, pigmentation, pollen wall assembly, developmental process, regulation of leaf senescence, leaf senescence, secondary metabolism, and defense response. It is linked to hull color and oxidative stress response. The encoded protein localizes to the cytoplasm. Related genes in other species connect the family to EC 2.3.1.95, EC 2.3.1.211, and EC 2.3.1.74 activities.
