CHS — Oryza sativa Indica Group

Summary

BGIOSGA033874 (CHS1) on chromosome 11 of Indica rice encodes a type III polyketide synthase with chalcone synthase, naringenin-chalcone synthase, flavonol synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, tetraketide alpha-pyrone synthase, chalcone isomerase, SUMO transferase and acyltransferase activities. The gene is associated with regulation of flavonoid anabolism, chalcone anabolism, polyketide anabolism, flavonol biosynthetic process, pigmentation, pollen wall assembly, response to UV, response to gravity, auxin polar transport, regulation of leaf senescence, and developmental process. It is linked to hull color, seed coat color, anthocyanin content, UV light sensitivity, stamen morphology trait, root phototropism response trait, stomatal opening, flowering time trait, drought tolerance, salt stress tolerance, and oxidative stress response. The protein localises to the cytosol, nucleus, ER, tonoplast and is extrinsic to the ER membrane.
