PHO2 — Phaseolus vulgaris

Summary

PHAVU_006G185400, designated PvPHO2 or PvUBC24, encodes a ubiquitin-conjugating enzyme (E2) with ubiquitin-protein transferase activity, inositol hexakisphosphate binding, and phosphate transmembrane transporter activity. It is associated with phosphate homeostasis, intracellular phosphate ion homeostasis, cellular response to phosphate starvation, polyphosphate anabolism, regulation of phosphate membrane transport, protein polyubiquitination, and ubiquitin-dependent proteolysis. The gene is linked to shoot system phosphorus content, phosphorus uptake, phosphate accumulation, phosphate translocation, phosphate starvation response, leaf senescence, flowering time, low temperature stress response, abscisic acid sensitivity, salt stress response, fungal pathogen resistance, and frost tolerance. It localizes to the nucleus, endoplasmic reticulum, Golgi complex, trans-Golgi network, mitochondria, and plasma membrane. Related genes in other species are linked to arsenic accumulation and phosphate loading to xylem.
