PR10 — Phaseolus vulgaris

Summary

PHAVU_003G109801, designated PvPR10, is a PR10 gene on French bean (Phaseolus vulgaris) chromosome 3. It encodes a Bet_v_I/MLP family protein with a START-like domain, possessing multiple molecular functions including melatonin, cytokinin, and abscisic acid binding, RNA nuclease activity, protein phosphatase inhibitor activity, hydrolase activity, signaling receptor activity, and calcium ion binding. PvPR10 is associated with regulation and downregulation of photosynthesis, seed germination, proteolysis, nodulation, ABA signaling, root development, and defense response. It localizes to the cytosol, cytoplasm, and nucleus. The gene is linked to drought tolerance. Studies of related genes in other species connect the PR10 family to ribonuclease activity (EC 3.1.27.-).
