Molecular analysis of evolutionary changes in populations of Ophiostma novo-ulmi ; Análisis molecular de los cambios evolutivos en poblaciones de Ophiostoma novo-ulmi

The spread of Ophiostoma novo-ulmi across Europe, North America and central Asia, resulted in the current, highly destructive Dutch elm disease (DED) pandemic, replacing O. ulmi, responsible for the first DED pandemic in the early 1900s. This process has resulted in a series of remarkable evolutionary and adaptive developments. Studies of O. novo- ulmi populations in the 1980s, especially in Spain and Portugal, showed the following: 1) that O. novo-ulmi initially spread across Europe as a series of genetic clones; 2) that deleterious RNA viruses were transmitted within the O. novo-ulmi clones;...
