Viral and Viroid Diseases


Here we report a novel method to extract nucleic acids for virus detection. Plant tissue in a filter paper sandwich was hit with a hammer, and the crude sap was adsorbed by the filter paper, as in hammer blotting for tissue-print immunodetection of plant viruses. Nucleic acids were extracted from the paper with a guanidine-containing buffer and purified through standard extraction and precipitation. Both viral and cellular RNAs in the extracted RNA were detectable by RT-PCR. The blots can be stored at 4 °C for more than a few days to detect viral RNA, but not cellular RNA.
