CHS — Oryza sativa Indica Group

Summary

BGIOSGA018588 (symbol CHS, also known as OiCHS) on chromosome 5 of Indica rice encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, flavonol synthase, and trihydroxystilbene synthase activities. The gene is associated with regulation of flavonoid, anthocyanin, and phenylpropanoid metabolism, as well as pollen wall assembly, pigmentation, response to UV, auxin polar transport, and leaf senescence. It is linked to traits including hull and seed coat color, anthocyanin content, drought tolerance, salt tolerance, flowering time, root morphology, and stamen morphology. Related genes in other species are associated with pollen exine development, male fertility, UV-B tolerance, flavonoid production, and seed coat pigmentation.
