UPS1 — Phaseolus vulgaris

Summary

PHAVU_003G042700, designated PvUPS1, encodes a ureide permease family protein with xanthine transmembrane transporter activity, allantoin:proton symporter activity, uracil:monoatomic cation symporter activity, and protein transporter activity. This French bean gene on chromosome 3 is associated with xanthine and allantoin transport, pyrimidine base salvage, nitrogen compound transport, phloem loading, nodulation, and salinity response. It localizes to the cell plate, secretory vesicle, trans-Golgi network, endoplasmic reticulum, membrane, mitochondria, and plasmalemma. PvUPS1 is associated with plant growth, salt stress tolerance, 5-fluorouracil tolerance, defense response, camalexin accumulation, and oxidative stress response. Studies of related genes in other species connect the family to uracil transport, nitrogen uptake, and stress tolerance.
