MoPer1 is required for growth, conidiogenesis, and pathogenicity in Magnaporthe oryzae
Abstract Background GPI-anchoring is a prevalent Glycosylphosphatidylinositol modification process of posttranslational protein and is necessary for cell wall integrity in eukaryotes. To date, the function of GPI anchored-related protein remains unknown in phytopathogenic fungi. Results We here char...
