PR1 — Fusarium graminearum PH-1

Summary

FGRAMPH1_01G11753 (PR1) on chromosome 2 of Fusarium graminearum PH-1 encodes a protein with serine-type endopeptidase activity, belonging to the peptidase S8 subtilisin-like family and containing a metal-binding domain. The gene is associated with a wide range of biological processes, including defense response, systemic acquired resistance, induced systemic resistance, innate immunity, proteolysis, nitrogen fixation, photosynthesis, embryogenesis, seed and spore germination, metabolic burst, detoxification, fermentation, and NO storage. It is linked to extracellular. Associations with traits include chlorophyll content, root length, and germination rate. Studies of related genes in other species link the family to cuticle degradation, unaffected pathogenicity, and associations with fusarium ear blight and drought tolerance, though these are not established for this specific gene.
