Incidence and stability of infection by double-stranded RNA genetic elements in Aspergillus section flavi and effects on aflatoxigenicity.

Ninety two isolates belonging to Aspergillus sect. Flavi were analysed for double-stranded (ds) RNA via standard cellulose chromatography.  Double-stranded RNA infection was detected in 5 of 26 fungal isolates that had been in culture for long periods and in 5 of 66 of those recently isolated.  Attempts to cure six fungal isolates of dsRNA by serial single condial transfer, chlorate selection for nitrogen-metabolism mutants and cycloheximide treatment, met with variable results.  Comparison of aflatoxin production prior to and after dsRNA curing indicated that infection by dsRNA did not influence aflatoxin production.
