CHS — Beta vulgaris subsp. vulgaris

Summary

BvCHS (BVRB_9G210980) on sugar beet chromosome 9 encodes a chalcone/stilbene synthase family protein with polyketide synthase type-III domains, annotated with naringenin-chalcone synthase, chalcone isomerase, flavanone 4-reductase, flavonol synthase, and SUMO transferase activities. The gene is associated with chalcone, flavonoid, anthocyanin, polyketide, and carotenoid biosynthesis, as well as responses to UV-B, jasmonic acid, oxidative stress, gravity, and heat acclimation. It is linked to root yield, photosynthetic rate, respiration rate, flowering time, root morphology, anthocyanin content, stomatal opening, and abiotic stress tolerance traits including salt and drought tolerance. Localization evidence connects the product to the cytosol, nucleus, endoplasmic reticulum, and tonoplast. Studies of related genes in other species link the family to pollen exine development, male fertility, sporopollenin biosynthesis, and disease resistance.
