ANS — Beta vulgaris subsp. vulgaris

Summary

BvANS (BVRB_5G101480) on sugar beet chromosome 5 encodes a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase, flavonol synthase, and flavanone 3-dioxygenase activities. The gene is associated with anthocyanin, proanthocyanidin, coumarin, and carotenoid biosynthesis, vacuole organization, and responses to jasmonic acid, wounding, oxidative stress, and fungal molecules. It localizes to the cytosol and cytoplasm. Associations include photosynthetic rate, UV light sensitivity, cold stress response, nematode susceptibility, and seed pigmentation. Studies of related genes in other species link the family to anthocyanin pigmentation, photoprotection, high light stress tolerance, and traits including flower and fruit color, leaf color, plant width, inflorescence height, shoot dry weight, fruit weight, starch content, chlorophyll content, net photosynthetic rate, stomatal resistance, pollen fertility, and drought tolerance.
