PR1 — Asparagus officinalis

Summary

A4U43_C07F14870 (PR1) in asparagus (Asparagus officinalis) on chromosome 7 encodes a protein with a Bet_v_I_allergen domain and a START-like domain superfamily, and is annotated with abscisic acid binding, protein phosphatase inhibitor activity, and signaling receptor activity. The gene is associated with ABA signaling, defense response, and response to wounding, and its product localizes to both the cytoplasm and nucleus. Related genes in other species link the family to plant defense hormone signaling and major latex protein domains, though these associations are not yet established in asparagus.
