ASPG1 — Phaseolus vulgaris

Summary

PHAVU_004G160200, designated PvASPG1, encodes an aspartic peptidase A1 family protein on French bean chromosome 4. The product possesses aspartic-type peptidase activity and aspartic endopeptidase activity, and is annotated for IgE binding, protein phosphorylated amino acid binding, ATP binding, and protein binding. PvASPG1 is associated with proteolysis, regulation of programmed cell death, systemic acquired resistance, defense response, brassinosteroid-mediated signalling, and response to abscisic acid and thirst. It has been linked to drought avoidance, seed germination, and root morphology traits. The protein localises to the apoplast, ER, plasmodesma, chloroplast stroma, extracellular space, mitochondria, cytosol, plasmalemma, cytoplasm, and nucleus. Studies of related genes in other species connect the family to seed longevity, viability, dormancy, growth and development, abscisic acid sensitivity, and drought tolerance.
