nit — Fusarium oxysporum f. sp. lycopersici 4287

Summary

FOXG_03931 (symbol nit) on chromosome 4 of Fusarium oxysporum f. sp. lycopersici 4287 encodes a protein belonging to the nitrilase/cyanide hydratase family, with annotated arylacetonitrilase, hydro-lyase and aminoacyl-tRNA ligase activities. The gene is associated with nitrate metabolism and nitrate assimilation. Expression of nit has been detected in vitro and at 2, 4 and 6 days post inoculation in tomato. Studies of related genes in other species link the family to nitrate transport and uptake, as well as to nitrogen and molybdenum content. Phenotypic analyses of related sequences connect the family to heat sensitivity, osmotic stress resistance, chronological lifespan, competitive fitness, and autophagy.
