ANS — Brassica napus

Summary

BnANS (DARMORV10_A01P14100.1) on chromosome A01 of oilseed rape encodes a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase, flavonol synthase, and flavanone 3-dioxygenase activities. The gene is associated with anthocyanin metabolism, proanthocyanidin biosynthesis, pigment accumulation, and flavonoid metabolism, as well as with seed color, seed coat color, leaf color, anthocyanin content, seed size, and photosynthetic rate. It has also been linked to vitamin B6 and vitamin A metabolism, cell cycle transition, sucrose and triglyceride anabolism, and coumarin anabolism. Localisation evidence indicates the product resides in the cytosol and cytoplasm. Studies of related genes in other species link the family to anthocyanin pigmentation, seed pigmentation, photoprotection, high light stress tolerance, and chlorophyll content.
