IAP1 — Phaseolus vulgaris

Summary

PHAVU_009G185000, designated PvIAP1 on French bean chromosome 9, encodes a protein with a LON protease N-terminal domain and a RING zinc finger, conferring ubiquitin ligase activity, DNA-binding transcription factor activity, and protein dimerization activity. The gene is associated with protein modification, homeostasis, seed development, and the regulation of cell differentiation and division. It has been linked to guard cell fate commitment, guard mother cell differentiation, stomatal development, and myrosin idioblast development. Associations also include basal immunity, increased resistance to Pto DC3000, and decreased osmotic, salt, and hypoxia stress tolerance. The product localises to the plasma membrane, cytoplasm, and nucleus. Studies of related genes in other species connect the family to age-related resistance and root gravitropism.
