✦ Synopsis

We report the extraction of delta virus RNA from the serum of a delta-virus-infected patient and the subsequent cloning and analysis of a 380-nucleotide-long cDNA (D380). The nucleotide sequence of D380 shows overall differences of approximately 20% when compared with previously published sequences and does not include the viroid consensus sequence previously reported (Wang et al: Nature 323:508-514, 1986). A potentially coding open reading frame extending over the whole length of the D380 has been identified. Our results demonstrate the existence of genetic heterogeneity amongst different delta virus isolates.

Strains of the budding yeast, Saccharomyces cerevisiae, may contain one or more cytoplasmic viruses with double-stranded RNA (dsRNA) genomes. The killer phenomenon in yeast, in which one cell secretes a killer toxin that is lethal to another cell, is dependent upon the presence of the L-A and M1 dsR
