Abstract
Of the genome of feline panleukopenia virus, .apprx. 80% was cloned into pBR322. This DNA included the transcription unit for the major viral mRNA species. The nucleotide sequence of the cloned portion of the genome was determined. Comparison of the feline panleukopenia virus sequence with the sequences of the parvoviruses minute virus of mice and H-1 revealed considerable homology between the 3 viruses on both the nucleic acid and protein levels. Based on this homology, a model for the generation of the 2 size classes of viral structural proteins (VP1 and VP2'') is proposed.
