AMT1 — Brassica napus

Summary

BnAMT1 (DARMORV10_C09P71100.1) on chromosome C09 of oilseed rape encodes an anthranilate synthase/aminodeoxychorismate synthase, a protein with ADC synthase and chorismate-binding domains. The gene is associated with tryptophan formation, auxin anabolism, anthocyanin anabolism, flavonoid anabolism, sucrose anabolism, folate biosynthesis, tetrahydrofolate anabolism, PABA biosynthesis, glutamine metabolism, nitrate import, photorespiration, leaf senescence, response to ethylene, wounding, and bacteria, and hypersensitivity. It is linked to the anthranilate synthase complex, chloroplast stroma, and cytoplasm. Traits associated with this gene include adventitious root formation, lateral root formation, root growth inhibition, nitrate uptake, ammonium uptake, auxin biosynthesis, alpha-methyltryptophan resistance, and PIN2 endocytosis. Studies of related genes in other species link the family to ammonium transport, primary root elongation, defense response, and phytoalexin biosynthesis.
