PR10 — Phaseolus vulgaris

Summary

PHAVU_003G109401, designated PvPR10, encodes a Bet v I/MLP family protein on French bean chromosome 3. The product exhibits 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. It is associated with downregulation and regulation of photosynthesis, seed germination, proteolysis, nodulation, ABA signaling, root development, and defense response. The protein localizes to the cytosol, cytoplasm, and nucleus. PvPR10 is linked to drought tolerance. Studies of related genes in other species, linked by sequence similarity, connect the family to ribonuclease activity (EC 3.1.27.-).
