PR1 — Asparagus officinalis

Summary

A4U43_C07F14410, designated PR1 in asparagus (Asparagus officinalis) on chromosome 7, encodes a Bet_v_I/MLP family protein with abscisic acid binding, protein phosphatase inhibitor, and signaling receptor activities. The gene is associated with ABA signaling, defense response, and response to wounding, and its product localizes to both the cytoplasm and nucleus. Studies of related genes in other species link the family to Bet v I/major latex protein domain-containing sequences, though these associations are not yet established in asparagus. The gene is also connected to PR1 and PR2 family members.
