PR5 — Sorghum bicolor

Summary

SORBI_3001G145700 (SbPR5, also known as SbOSM34) encodes a thaumatin-like protein containing a thaumatin domain and osmotin/thaumatin-like superfamily domain, with annotated serine-type endopeptidase inhibitor activity, glycosidase activity, and protein binding. The gene is associated with defence responses to fungi and bacteria, response to UV-B, seed germination, salinity response, and killing of cells of other organisms. It is linked to extracellular, vacuolar, and secretory vesicle localisation, as well as photosynthetic rate, respiration rate, osmotic stress response, proline accumulation, and abscisic acid response. Studies of related genes in other species connect the family to grain yield, drought tolerance, stem rust, grain texture, chlorophyll content, and root length.
