PR1 — Oryza sativa Indica Group

Summary

BGIOSGA022877 (symbol PR1, also known as OiPR1) on chromosome 6 of Indica rice encodes a protein belonging to the CRISP-related CAP domain family. The product exhibits cytokine activity and protein binding, and is localised to the secretory vesicle, vacuole, plant-type cell wall and extracellular space. PR1 is associated with activation of immune response, cytokine production, defense response to other organism, and responses to jasmonic acid, ethylene, salicylate, wounding, herbivory, and bacteria. It is linked to secondary metabolite biosynthesis, diterpenoid anabolism, sexual reproduction, and priming of cellular response to stress. In this species, PR1 is associated with seedling and root phenotypes, defense, and resistance to root knot nematode, as well as responses to jasmonate, salicylic acid, ethylene, gibberellin, and other phytohormones. Related genes in other species link the family to salicylic acid-mediated defense, systemic immunity, and resistance to fungal and viral pathogens.
