Preliminary studies on the RNA components of three strains of cucumber mosaic virus
Coutts, Robert H.A.
In investigations of the causal relationships between disease symptoms and virus infection of plants, three strains of cucumber mosaic virus (viz. N, Price's No. 6 and W) which caused different symptoms in several plant species were studied. The ribonucleic acid components of the three strains were resolved by electrophoresis in 2·4% polyacrylamide/0·5% agarose gels and their sizes relative to those of the two ribosomal RNAs of Escherichia coli estimated. All three strains contained the four major RNA species
