RNA/cDNA hybridization studies of UK isolates of barley yellow mosaic virus

Abstract
The RNA components of two isolates of BaYMV from Streatley and Wiltshire were analysed by agarose gel electrophoresis. Northern blots of extracts of both isolates analysed with random‐primed cDNA probes to RNA1 and 2 of the Streatley isolate showed little or no sequence homologies between the two isolates, confirming other evidence that they should be considered as different viruses.
