CHS — Oryza sativa Indica Group

Summary

BGIOSGA024426 (symbol CHS, preferred name OiCHS) on chromosome 7 of Indica rice encodes a chalcone synthase, a type III polyketide synthase with naringenin-chalcone synthase, biphenyl synthase, and tetraketide alpha-pyrone synthase activities. The gene is associated with regulation of flavonoid anabolism, chalcone anabolism, polyketide anabolism, S phase, metabolic burst, pigmentation, pollen wall assembly, developmental process, regulation of leaf senescence, leaf senescence, and secondary metabolism. It is linked to hull color and oxidative stress response. The encoded protein localizes to the endoplasmic reticulum and exhibits protein homodimerization and identical protein binding activities. Studies of related genes in other species connect the family to chalcone synthase activity (EC 2.3.1.74) and broader acyltransferase functions.
