PR1 — Asparagus officinalis

Summary

A4U43_C07F14420, designated PR1 on asparagus chromosome 7, encodes a Bet v I/Major latex protein (MLP) domain-containing protein with nuclease, hydrolase, abscisic acid (ABA) binding, signaling receptor, and protein phosphatase inhibitor activities. The product is associated with defense responses, response to wounding, and ABA signaling, and localizes to both the cytoplasm and nucleus. The gene is linked to PR1 and PR2 family members. Studies of related genes in other species connect this family to nuclease activity (EC 3.1.27.-), though this has not been established for the asparagus gene itself.
