Summary S accharomyces cerevisiae protein kinase Sch 9 is one of the downstream effectors of the target of rapamycin ( TOR ) complex 1 and plays multiple roles in stress resistance, longevity and nutrient sensing. However, the functions of Sch 9 orthologs in filamentous fungi, particularly in pathogenic species, have not been characterized to date. Here, we investigated biological and genetic functions of FgSch 9 in F usarium...
