OSM34 — Cicer arietinum

Summary

CaOSM34 (LOC101501337) on chickpea chromosome 8 encodes a thaumatin-like protein with beta-glucanase and endo-1,3(4)-beta-glucanase activity, placing it in the osmotin/thaumatin-like superfamily. The gene is associated with defence responses, including antifungal and antibacterial innate immune responses, response to viruses and fungi, and killing of cells of other organisms. It is linked to responses to ethylene and jasmonic acid, xenobiotic breakdown, metabolic burst, and regulation of DNA replication. The product localises to the apoplast, vacuole, and secretory vesicles. CaOSM34 is associated with osmotic stress response, proline accumulation and biosynthesis, and abscisic acid response. Studies of related genes in other species link the family to drought tolerance, salt response, transpiration rate, stomatal resistance, and biomass yield.
