Laccases (benzenediol: oxygen oxidoreductases, EC 1.10.3.2) belong to a family of blue multicopper oxidases that catalyze the oxidation of a variety of aromatic substrates along with the reduction of molecular oxygen to water [1]. Laccases have attracted extensive attention due to their functional diversity; for example, they are involved in lignin biodegradation, plant pathogenesis, and stress...

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 genetic...
