  • Title: Replication footprint analysis of cucumber mosaic virus electroporated into tomato protoplasts.
    Author: Smith CR, Tousignant ME, Kaper JM.
    Journal: Anal Biochem; 1992 Feb 01; 200(2):310-4. PubMed ID: 1378705.
    Abstract:
    Total RNA extracted from cucumber mosaic virus (CMV) strains WT, with its associated satellite CARNA 5 (CMV-associated RNA 5), was successfully electroporated into isolated tomato protoplasts. At various time intervals samples were extracted for total nucleic acids and analyzed by semidenaturing polyacrylamide gel electrophoresis (PAGE). Sequence-specific hybridization probes were used for the detection of viral and satellite RNAs following Northern transfer. The resulting PAGE patterns and/or autoradiographs depict the proportional presence of viral and satellite RNAs in the extracts over time and have been referred to as "replication footprint profiles" (RFPs) of specific CMV/CARNA 5 combinations. The effective isolation and infection of tomato protoplasts, combined with the ability to follow virus/satellite titers during the infection by RFP analysis, yield results similar to those of infected plants and reduces experiments of 21 or more days in whole plants to less than 72 h in protoplasts.
