LARGETEAU, Michèle L.; MATA, Gerardo  e  SAVOIE, Jean-Michel. Verticillium fungicola var. fungicola: comparison of some Mexican and French isolates. Rev. Mex. Mic [online]. 2008, vol.26, pp.35-40. ISSN 0187-3180.

Isolates of Verticillium fungicola collected in 2002 in the Veracruz State, Mexico, and previously identified as V. fungicola var. fungicola, were compared to French isolates for genetic polymorphism and diversity in some physiological traits. Results were analysed based on studies of a larger group of European V. fungicola var. fungicola. RAPD analyses showed that Mexican isolates were genetically similar to those collected in Western Europe over the period 1987-2000. Mycelial growth rate, antibiosis effect against their host Agaricus bisporus, and in vitro sensitivity to the fungicide chlorothalonil did not distinguish the Mexican isolates from the European isolates studied.

Palavras-chave : Agaricus bisporus; edible mushroom; fungal pathogen; genetic diversity; physiological variability.
