PR5 — Brachypodium distachyon

Summary

BdPR5 (BRADI_3G04330V3) on chromosome 3 of Brachypodium distachyon encodes a thaumatin-like protein, a member of the osmotin/thaumatin-like superfamily. The gene is associated with defence responses, including defence against fungi, cell death, and responses to salicylate, ethylene, and abscisic acid. It is also linked to salinity response, pollen hydration and germination, and the killing of cells of other organisms. The protein localises to the apoplast, vacuole, Golgi, vesicles, and pollen wall layers such as the intine, exine, tryphine, and orbicule. Related genes in other species encode thaumatin-like proteins, including pollen allergens and pathogenesis-related proteins.
