PID3 — Oryza sativa Indica Group

Summary

BGIOSGA021323 (symbol PID3) on chromosome 6 of indica rice encodes a protein with NB-ARC, LRR, and RX-like CC domains, characteristic of plant disease resistance proteins. It binds ADP, ATP, and metal ions. PID3 is associated with resistance to the blast fungus Magnaporthe oryzae, as well as with breeding, leaf traits, and blast resistance. The gene is linked to defence responses to bacteria and other organisms, innate immune response-activating signalling, regulation of pattern recognition receptor signalling, antiviral response, and hypersensitive response-programmed cell death. It is also associated with translation initiation. The encoded protein localises to the membrane, cytosol, cytoplasm, and plasmalemma. Studies of related genes in other species link the family to defence signalling.
