abstract：:SUMMARY Two of the currently widely accepted species in the section Nigrescentia of the genus Verticillium are major plant pathogens inducing wilt diseases in a wide range of mainly dicotyledonous hosts. Three species closely related to these two are less important wilt pathogens and soil saprophytes. A sixth species,...

abstract：:SUMMARY Phytopathogenic fungi must feed on their hosts to propagate and cause disease. Their ability to access the rich nutrient supply offered by living plants is one of the most obvious properties that distinguish pathogens from saprophytes. Successful invasion by pathogens depends as much on their ability to utiliz...

The fungus Acremonium implicatum can develop an endophytic association that is mutually beneficial with Brachiaria species. We developed a polymerase chain reaction (PCR)-based method by first amplifying DNA from A. implicatum isolates using...

The pathogen itself also generates active oxygen species and H(2)O(2) as pathogenicity factors. Our aim was to study how the pathogen may defend itself against cellular damage caused...
