| Abstract: | This study provides both direct and indirect evidence that, in Costa Rica, rice hoja blanca virus and Echinochloa hoja blanca virus occupy distinct ecological niches, implying that their molecular differences are the result of evolutionary divergence rather than variation within a single virus population. For this reason they should be considered separate virus species, rather than strains of a single species. |
