CHS — Oryza sativa Indica Group

Summary

BGIOSGA001262 (CHS, OiCHS) on indica rice chromosome 1 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, flavonol synthase, and tetraketide alpha-pyrone synthase activities. The gene is associated with the regulation of flavonoid, anthocyanin, and phenylpropanoid metabolism, as well as pollen wall assembly, pigmentation, response to UV light, auxin polar transport, and leaf senescence. It has been linked to traits including hull and seed coat color, anthocyanin content, drought and salt stress tolerance, flowering time, root morphology, and stomatal opening. Related genes in other species are linked to pollen exine development and male fertility, UV-B tolerance, flavonoid production, and seed coat pigmentation.
