ANS — Brassica juncea

Summary

BJUA03G12340S (BjANS, also known as TT18, BjLDOX, or BjTT18) on chromosome A03 of Indian mustard (Brassica juncea) encodes a protein with a DIOX_N domain and an Oxoglu/Fe-dep_dioxygenase_dom, and has oxidoreductase activity acting on paired donors with incorporation or reduction of molecular oxygen, with 2-oxoglutarate as one donor, and the other dehydrogenated, as well as leucocyanidin oxygenase, flavonol synthase, and flavanone 3-dioxygenase activities. The gene is associated with anthocyanin, proanthocyanidin, flavonoid, and phenylpropanoid biosynthesis, as well as pigmentation, seed development, leaf formation, vacuole organization, and cell cycle transition. It localizes to the cytosol and cytoplasm. Associations include seed color, leaf color, seed size, anthocyanin content, photosynthetic rate, UV light sensitivity, nematode susceptibility, and responses to fungal molecules. Studies of related genes in other species link the family to seed coat color, chlorophyll content, net photosynthetic rate, and high light stress tolerance.
