Occurrence of putative endornaviruses in non-cultivated plant species in South Louisiana

Extraction and electrophoretic analysis of viral dsRNA from plants has been used successfully to detect infections by RNA viruses. We used this approach as an initial tool to test non-cultivated plant species for the presence of endornaviruses. Foliar samples were collected from symptomless plants in various locations within East Baton Rouge Parish, Louisiana, USA, and tested for viral dsRNA. After testing 208 plant species belonging to 74...
