PR1 — Magnaporthe oryzae 70-15

Summary

MGG_10449 (PR1) on chromosome 2 of Magnaporthe oryzae 70-15 encodes a serine-type endopeptidase belonging to the peptidase S8 subtilisin-related family, with metal-binding capacity. The gene is associated with defense response, innate immunity, programmed cell death, and appressorium formation, as well as with JA signaling, lignin anabolism, and proteolysis. It is linked to extracellular and to traits including leaf curling, lignin content, chlorophyll content, drought tolerance, and heterosis. Studies of related genes in other species connect the family to cuticle degradation and to traits such as root dry weight, root length, and germination rate, though these associations are not established for PR1 itself.
