FLS — Brassica juncea

Summary

BJUA02G01710S (symbol FLS) on Indian mustard chromosome A02 encodes a 2-oxoglutarate/Fe(II)-dependent dioxygenase with flavonol synthase, leucocyanidin oxygenase and flavanone 3-dioxygenase activities, and binds vitamin C and metal ions. The product localises to the cytoplasm and is associated with pigmentation, anthocyanin and coumarin biosynthesis, nitric oxide storage, and response to fungal elicitors. Studies of related genes in other species link the family to EC 1.14.20.4, EC 1.14.20.6 and EC 1.14.11.9, reinforcing the enzyme's role in flavonoid metabolism.
