Corky root is caused by Pyrenochaeta lycopersici, a soil-borne plant pathogen producing conidia within pycnidia and melanized microsclerotia. On agar media, the fungus appears as a so-called 'gray sterile fungus', because it produces only mycelium and dark microsclerotia, but not pycnidia. For a definitive species identification, particular procedures can be adopted to stimulate the production of pycnidia or a PCR-based protocol can be used.

Abstract
Corky root is caused by Pyrenochaeta lycopersici, a soil-borne plant pathogen producing conidia within pycnidia and melanized microsclerotia. On agar media, the fungus appears as a so-called 'gray sterile fungus', because it produces only mycelium and dark microsclerotia, but not pycnidia. For a definitive species identification, particular procedures can be adopted to stimulate the production of pycnidia or a PCR-based protocol can be used.File in questo prodotto:
