ANS — Brassica oleracea var. botrytis

Summary

BoANS (BOLND125_C07P054980.1_BOLND125_V1) on cauliflower chromosome 7 encodes a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase, flavonol synthase, and flavanone 3-dioxygenase activities. The gene is associated with anthocyanin, proanthocyanidin, flavonoid, and phenylpropanoid biosynthesis and metabolism, as well as pigmentation, coumarin biosynthesis, and vacuole organization. It has been linked to anthocyanin content, photosynthetic rate, UV light sensitivity, and responses to cold, wounding, jasmonic acid, and fungal molecules. The encoded protein localizes to the cytosol and cytoplasm. Studies of related genes in other species connect the family to seed and leaf color, chlorophyll content, photosynthetic traits, seed size, lignin content, and stress tolerance, though these associations are not yet established in cauliflower.
