AMT2 — Brassica juncea

Summary

BJUA04G24280S (BjAMT2) on Indian mustard chromosome A04 encodes a protein with ammonium channel activity and is associated with ammonium membrane transport. The gene is associated with response to nematodes, arbuscular mycorrhizae formation, and response to symbiotic fungi, and its product localises to the periarbuscular membrane, plasmodesma, plasma membrane, and cytoplasm. BjAMT2 is associated with root senescence, root-to-shoot ammonium translocation, and ammonium uptake. Related genes in other species are linked to ammonium and nitrogen transport, and sequence similarity extends associations to traits including phosphorus and potassium concentration, nitrogen content and recycling, root number and branching, leaf size, and plant height.
