PT4 — Medicago truncatula

Summary

MTR_1G028600 (symbol PT4) in barrel medic (Medicago truncatula) chromosome 1 encodes a protein belonging to the major facilitator superfamily (MFS), with phosphate transmembrane transporter activity, symporter activity, and hydrolase activity. The gene is associated with phosphate ion transport and detection, cellular responses to phosphate starvation and nitrogen levels, arbuscular mycorrhizae formation, response to symbiotic fungi, morphogenesis, lateral root formation, root development, and response to thirst. The encoded protein localises to the periarbuscular membrane, plasma membrane, and membrane. PT4 is also linked to root branching. Studies of related genes in other species connect the family to phosphate transport in symbiosis.
