PR5 — Nicotiana attenuata

Summary

A4A49_36852 (NaPR5) on chromosome 2 of coyote tobacco encodes a pathogenesis-related protein 5, a member of the osmotin/thaumatin-like superfamily, with annotated glucan endo-1,3-beta-D-glucosidase activity, IgE binding, mRNA binding, and protein binding. The gene is associated with systemic acquired resistance, response to virus, bacteria, salicylate, ethylene, UV-B, cadmium, and arachidonate, as well as cell death, regulation of anthocyanin and ethylene anabolism, posttranscriptional gene expression, and cell wall biogenesis. Its product localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, plasmodesma, and mitochondria. NaPR5 is associated with disease resistance, including against Pseudomonas syringae and Verticillium dahliae, as well as insect resistance, salt and drought tolerance, osmotic stress response, proline accumulation, leaf curling, and ABA and UV-B stress responses.
