PR5 — Solanum lycopersicum

Summary

SlPR5 (SOLYC01G111330.4) encodes a protein belonging to the osmotin/thaumatin-like superfamily and the thaumatin family, with glucan endo-1,3-beta-D-glucosidase activity. It is associated with regulation of proline anabolism, ergosterol anabolism, lycopene anabolism, salicylic acid anabolism, auxin anabolism, chlorophyll anabolism, and regulation of anthocyanin anabolism, as well as photoperiodism, pigmentation, fermentation, mRNA breakdown, response to cadmium, and killing of cells of other organisms. The protein localises to the apoplast, plant-type cell wall, plant-type vacuole, plasmodesma, secretory vesicle, membrane, and mitochondria. SlPR5 is linked to fruit shape, sugar content, protein content, seed size, stomatal opening, and sensitivity to acid and abscisic acid. It is associated with disease resistance, including resistance to Verticillium dahliae and Pseudomonas syringae, as well as salt tolerance, drought tolerance, osmotic stress response, proline accumulation, and defense responses. Related genes in other species are linked to pathogen resistance, herbivore defense, nematode resistance, and seed germination under salt stress.
