MAP kinase Hog1 mediates a cytochrome P450 oxidoreductase to promote the Sporisorium scitamineum cell survival under oxidative stressNARA Subscribed
Summary The MAP kinase high osmolarity glycerol 1 (Hog1) plays a central role in responding to external oxidative stress in budding yeast Saccchromyces cerevisiae . However, the downstream responsive elements regulated by Hog1 remain poorly understood. In this study, we report that a Sporisorium scitamineum orthologue of Hog1, named as SsHog1, induced transcriptional expression of a putative cytochrome P450 oxidoreductase enco...
cAMP/PKA signalling pathway regulates redox homeostasis essential for Sporisorium scitamineum mating/filamentation and virulenceNARA Subscribed
Summary The fungal pathogen Sporisorium scitamineum causes sugarcane smut disease. The formation and growth of dikaryotic hypha after sexual mating is critical for S. scitamineum pathogenicity, however regulation of S. scitimineum mating has not been studied in detail. We identified and characterized the core components of the conserved cAMP/PKA pathway in S. scitamineum by reverse genetics. Our results showed that cAMP/PKA si...
