CHS — Beta vulgaris subsp. vulgaris

Summary

BvCHS (BVRB_1G018270) on sugar beet chromosome Bvchr1_un.sca002 encodes a protein with chalcone/stilbene synthase and polyketide synthase type-III domains, annotated with naringenin-chalcone synthase, trihydroxystilbene synthase, tetraketide alpha-pyrone synthase, chalcone isomerase, flavanone 4-reductase, dihydroflavanol 4-reductase, flavonol synthase, acyltransferase, SUMO transferase, and kinase binding activities. The gene is associated with chalcone, polyketide, flavonol, anthocyanin, monoterpenoid, triterpenoid, and wax biosynthesis, as well as regulation of flavonoid, phenylpropanoid, and anthocyanin metabolism, pollen wall assembly, response to gravity, nitrogen utilization, and glutamate and glutathione metabolism. It is linked to root yield, anthocyanin content, flowering time, photosynthetic rate, respiration rate, UV light sensitivity, oxidative stress response, salt stress tolerance, drought tolerance, root morphology, stamen morphology, and stomatal opening. Studies of related genes in other species connect the family to flavonoid production, seed coat pigmentation, pollen exine development, male fertility, and disease resistance.
