CHS — Oryza sativa Indica Group

Summary

BGIOSGA033154, designated OiCHS on chromosome 10 of Indica rice, encodes a protein with chalcone/stilbene synthase and polyketide synthase type III domains and is annotated with naringenin-chalcone synthase, trihydroxystilbene synthase, tetraketide alpha-pyrone synthase, and acyltransferase activities. The gene is associated with chalcone and polyketide biosynthesis, flavonoid metabolism, pigmentation, pollen wall assembly, leaf senescence, and defense responses. It has been linked to hull color and oxidative stress response. The encoded protein localises to the endoplasmic reticulum and cytoplasm, and is annotated with protein homodimerization and identical protein binding activities, and with S phase, metabolic burst, and developmental processes. Related genes in other species link the broader gene family to EC 2.3.1.74, 2.3.1.95, and 2.3.1.333 activities.
