PR10 — Pisum sativum

Summary

PSAT1G157000 (symbol PR10) on garden pea chromosome 1LG6 encodes a pathogenesis-related protein 10, a member of the Bet v I/major latex protein family with a START-like domain. The product exhibits melatonin, cytokinin, and abscisic acid binding, RNA nuclease, hydrolase, signaling receptor, calcium ion binding, and protein phosphatase inhibitor activities. It is associated with nitrogen fixation, nodulation, ABA signaling, and defence responses to fungi. The protein localises to the cytosol, cytoplasm, and nucleus. PR10 is also linked to salt response. Studies of related genes in other species connect the family to ribonuclease activity (EC 3.1.27.-) and to traits including quantum yield, starch content, and photochemical quenching.
