PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC03G033490.3) encodes a protein belonging to the osmotin/thaumatin-like superfamily and is annotated with glucan endo-1,3-beta-D-glucosidase activity, IgE binding, mRNA binding, and protein binding. This gene is associated with the regulation of proline, anthocyanin, lycopene, chlorophyll, auxin, ethylene, and salicylic acid anabolism, as well as photoperiodism, fermentation, response to cadmium, and the killing of other cells. It localizes to the apoplast, plant-type cell wall, vacuole, plasmodesma, secretory vesicle, membrane, and mitochondria. SlPR5 is associated with fruit shape, sugar and protein content, seed size, stomatal opening, and sensitivity to abscisic acid and acid. It is also linked to disease resistance against Verticillium dahliae and Pseudomonas syringae, osmotic stress response, proline accumulation, salt and drought tolerance, and insect resistance. Related genes in other species link the family to viral susceptibility and seed germination under salt stress.
