CHS — Oryza sativa Japonica

Summary

Os07g0501100 (CHS) in 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 flavonoid and anthocyanin biosynthesis, pigmentation, pollen wall assembly, and responses to UV light and gravity. It has been linked to traits including grain weight, seed coat color, leaf color, anthocyanin content, starch content, root length, chlorophyll content, drought tolerance, heat tolerance, salt tolerance, and germination rate. Related genes in other species connect the family to flavonoid biosynthesis, seed coat pigmentation, UV-B tolerance, and pollen exine formation.
