CHS — Oryza sativa Indica Group

Summary

BGIOSGA018587 (CHS, OiCHS) on indica rice chromosome 5 encodes a type III polyketide synthase with chalcone/stilbene synthase domains, annotated with naringenin-chalcone synthase, trihydroxystilbene synthase, tetraketide alpha-pyrone synthase, bisdemethoxycurcumin synthase, chalcone isomerase, flavonol synthase, flavanone 4-reductase, dihydroflavanol 4-reductase, SUMO transferase, and acyltransferase activities. The gene is associated with chalcone, flavonoid, anthocyanin, polyketide, and phenylpropanoid biosynthesis, pollen wall assembly, pigmentation, response to UV and gravity, auxin polar transport, regulation of leaf senescence, and S phase. It has been linked to hull color, seed coat color, anthocyanin content, drought tolerance, salt stress tolerance, root morphology, flowering time, stamen morphology, root phototropism, stomatal opening, oxidative stress response, and abiotic stress tolerance. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Related genes in other species are linked to flavonoid production, UV-B tolerance, seed coat pigmentation, pollen exine formation, and male fertility.
