UGP — Phaseolus vulgaris

Summary

PHAVU_008G240600, designated PvUGP, encodes a protein belonging to the UDPGP family. This French bean gene on chromosome 8 is associated with UDP-glucose metabolism, glycogen metabolism, cell wall callose deposition, and plasmodesma-mediated cell-to-cell transport. It has been linked to pollen development, phosphate starvation responses, and antiviral defense, with the protein localizing to the cytosol, Golgi, plastid, cell wall, and plasmodesmata. PvUGP is associated with plant stress response, disease tolerance, root morphology, and growth traits, including hypocotyl length, root gravitropism, male fertility, and programmed cell death. Related genes in other species are associated with seed yield, plant growth, and cold and drought tolerance.
