AP2 — Phaseolus vulgaris

Summary

PHAVU_003G080800 (PvAP2) encodes a protein with aspartic endopeptidase activity and contains saposin-like domains. In French bean, this gene is associated with proteolysis, primary metabolism, organogenesis, nodulation, nitrogen fixation, and responses to cadmium, thirst, and light intensity. It is linked to protein storage vacuoles, secretory vesicles, the vacuole, plasmodesmata, the nucleus, and the extracellular space. PvAP2 has been connected to photosynthetic rate, seed size, salt response, stomatal density, and stomatal aperture. Studies of related genes in other species link the family to grain yield, seed weight and length, root traits, leaf relative water content, net photosynthetic rate, transpiration rate, germination rate, and seed longevity.
