AMT1 — Phaseolus vulgaris

Summary

PHAVU_001G241600 (PvAMT1) on chromosome 1 of French bean encodes an anthranilate synthase/aminodeoxychorismate synthase with ADC synthase and chorismate-binding domains, possessing both anthranilate synthase and aminodeoxychorismate synthase activities. The gene is associated with tryptophan formation, regulation of auxin biosynthetic process, auxin anabolism, PABA biosynthesis, folate biosynthesis, tetrahydrofolate anabolism, response to bacteria, response to ethylene, response to wounding, and response to thirst. It localises to the chloroplast stroma, cytoplasm and anthranilate synthase complex. Associations include adventitious rootless, lateral root formation, root growth inhibition, ammonium uptake, sulfur nutrition response, PIN2 endocytosis, alpha-methyltryptophan resistance, and pale reticulated adult plants. Related genes in other species link the family to ammonium transport, primary root elongation, defense response, phytoalexin biosynthesis, and traits including root branching, drought tolerance, water use efficiency, chlorophyll content and stomatal opening.
