PR5 — Asparagus officinalis

Summary

A4U43_C04F3710 (PR5, also known as AoPR5, OSM-34, and AoTLP1) on asparagus chromosome 4 encodes a member of the osmotin/thaumatin-like superfamily with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, and mRNA binding. The protein localizes to the apoplast, plant-type cell wall, secretory vesicle, vacuole, plasmodesmata, membrane, and mitochondria. This gene is associated with systemic acquired resistance, defence responses to bacteria and fungi, response to viruses, ethylene, abscisic acid, UV-B, and cadmium, as well as regulation of anthocyanin anabolism and killing of cells of other organisms. It is linked to disease resistance, osmotic stress response, proline accumulation, salt and drought tolerance, insect resistance, and resistance to Verticillium dahliae and Pseudomonas syringae. Studies of related genes in other species connect the family to pathogen resistance, induced systemic resistance, and seed germination under salt stress.
