Abstract
A nucleic acid was isolated from leaves of sweet cherry (Prunus avium L.) infected with little cherry disease (LCD) by a method which is highly selective for double-stranded RNA (ds-RNA). The nucleic acid was susceptible to RNase in low salt but not in high salt and it was resistant to RNase-free DNase.
Its molecular weight, estimated by polyacrylamide gel electrophoresis using the ds-RNA of tissue infected with turnip yellow mosaic virus, as a standard, was slightly greater than 4X106. The ds-RNA was not obtained from sweet cherry known to be free of LCD nor from sweet cherry infected with known viruses.
