PR2 — Solanum lycopersicum

Summary

SOLYC11G065280.1, designated PR2 (also known as GLU2, SlGLUA2, SlPR2, SlSP41B, GLUA2, SP41B, SlGLU2) on tomato chromosome 11, encodes a protein belonging to the glycosyl hydrolase 17 family with lichenase and glucan endo-1,3-beta-D-glucosidase activity. This gene is associated with disease resistance, including virus resistance, and has been linked to induced systemic resistance, metabolic burst, and camalexin anabolism. It is associated with responses to water, stomatal closure, nonphotochemical quenching, and fermentation, as well as hormone and cuticle anabolism, meristem initiation, abscission, and stamen development. The encoded protein localises to the vacuole and extracellular space. Associations with agronomic traits include fruit weight, sugar and protein content, shoot fresh weight, root length, chlorophyll content, photosynthetic and transpiration rates, germination rate, seed maturation, and disease tolerance.
