PR1 — Oryza sativa Indica Group

Summary

BGIOSGA038229 (symbol PR1, also known as Pr1c) encodes a protein belonging to the CAP superfamily, containing a CAP domain and a V5 allergen-like domain, and is annotated with cytokine activity and protein binding. In indica rice, PR1 is associated with defense responses to pathogens, including resistance to root-knot nematode, and with responses to salicylic acid, jasmonic acid, ethylene, and gibberellin. It is linked to seedling, root, shoot, and leaf phenotypes, and to processes such as activation of immune response, response to herbivore, wounding, and secondary metabolite biosynthesis. The protein localizes to the extracellular space, plant-type cell wall, vacuole, and secretory vesicles. Studies of related genes in other species connect the PR1 family to systemic acquired resistance, disease resistance against fungi and viruses, and abiotic stress tolerance.
