CHS — Oryza sativa Indica Group

Summary

BGIOSGA033877 (symbol CHS, also known as OiCHS) on chromosome 11 of Indica rice encodes a chalcone synthase, a type III polyketide synthase with naringenin-chalcone synthase and bisdemethoxycurcumin synthase activities. The gene is associated with regulation of flavonoid anabolism, polyketide anabolism, pigmentation, pollen wall assembly, leaf senescence, and developmental processes. It has been linked to hull color and oxidative stress response. The encoded protein localizes to the cytoplasm and endoplasmic reticulum and shows identical protein binding. Studies of related genes in other species connect the family to additional acyltransferase activities (EC 2.3.1.218, 2.3.1.333, 2.3.1.211).
