Barley stripe mosaic virus (BSMV), the type member of the hordeivirus group, has a plus-stranded genome comprising RNA species designated alpha, beta, and gamma. Although RNA beta is essential for infection of whole plants, it is dispensable for infection of barley protoplasts. We have used a full-length cDNA clone of RNA beta from which infectious in vitro transcripts can be derived to construct a number of mutations in its four genes. Mutations introduced into the beta b, beta c, or beta d… CONTINUE READING
