CHS — Beta vulgaris subsp. vulgaris

Summary

BvCHS (BVRB_1G018750) on sugar beet chromosome Bvchr1_un.sca002 encodes a chalcone/stilbene synthase family protein with polyketide synthase type-III domains and multiple annotated enzyme activities, including naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with flavonoid, anthocyanin, chalcone, polyketide, and carotenoid biosynthesis, as well as responses to UV-B, jasmonic acid, gravity, and heat acclimation. It has been linked to root yield, anthocyanin content, flowering time, photosynthetic rate, stomatal opening, root morphology, and abiotic stress responses including salt and drought tolerance. Additional associations include pollen wall assembly, auxin polar transport, and regulation of phenylpropanoid metabolism. The protein localizes to the cytosol, nucleus, endoplasmic reticulum, and tonoplast.
