PR1 — Fusarium oxysporum f. sp. lycopersici 4287

Summary

FoPR1 (FOXG_14793) on chromosome 12 of Fusarium oxysporum f. sp. lycopersici 4287 encodes a subtilisin-like serine-type endopeptidase (peptidase S8 family) with protease activity and fibrinogen- and IgE-binding capabilities. The gene is associated with induced systemic resistance, symbiont-mediated suppression of host immunoglobulin-mediated immune responses and complement activation, zymogen activation, proteolysis, secretion, autophagy, host invasion, siderophore anabolism, conjugation with cellular fusion, and elastin breakdown. It is linked to extracellular, Golgi, fungal-type vacuole, and late endosome lumen localisation. Associations with root dry weight and chlorophyll content have been recorded. Related genes in other species link the family to drought tolerance and salt tolerance, and to apoplastic and cytoplasmic effectors.
