CHS — Oryza sativa Indica Group

Summary

BGIOSGA018590 (CHS, OiCHS) on chromosome 5 of Indica rice encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with multiple activities including naringenin-chalcone synthase, flavonol synthase, and trihydroxystilbene synthase. The gene is associated with flavonoid, anthocyanin, and polyketide biosynthesis, as well as pollen wall assembly, pigmentation, response to UV, auxin polar transport, and regulation of leaf senescence. It is linked to traits such as hull and seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root morphology, flowering time, and stomatal opening. Related genes in other species are associated with pollen exine development, male fertility, sporopollenin biosynthesis, and UV-B tolerance. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
