PHR — Fusarium oxysporum f. sp. lycopersici 4287

Summary

FOXG_01134, designated FoPHR (also known as PHR1 or FoPHR1) on chromosome 1 of Fusarium oxysporum f. sp. lycopersici 4287, encodes a cryptochrome/DNA photolyase family protein with CPD photolyase activity, damaged DNA binding, and FAD binding. The gene is associated with photoreactive repair, DNA repair, circadian regulation of gene expression, photoentrainment of the circadian clock, nucleobase-containing compound metabolism, and response to stress. Its product localises to the mitochondria, cytoplasm, and nucleus. Studies of related genes in other species link the family to decreased UV resistance, altered heat sensitivity, changes in oxidative stress resistance, reduced vegetative growth, and effects on competitive fitness and carbon source utilisation, though these phenotypes are not established for FoPHR itself.
