PR5 — Asparagus officinalis

Summary

A4U43_C07F33820, designated PR5 (also known as AoPR5, OSM-34, and AoTLP1) on asparagus chromosome 7, encodes a protein with mRNA and protein binding activities. The gene is associated with defence responses to bacteria, fungi, and viruses, as well as systemic acquired resistance and responses to ethylene, UV-B, and cadmium. It has been linked to the regulation of anthocyanin anabolism. The product localises to the apoplast, plant-type cell wall, secretory vesicle, vacuole, plasmodesma, membrane, and mitochondria. Associations include disease resistance, salt and drought tolerance, osmotic stress response, proline accumulation, and resistance to Verticillium dahliae and Pseudomonas syringae. Studies of related genes in other species connect the family to pathogen resistance, herbivore defence, seed germination under salt stress, and cell wall integrity.
