Abstract
Potato virus Y (PVY) infects economically important solanaceous crops in Zimbabwe. However, there is little information on the genome sequences of isolates occurring in this country. In this study, RNASeq of PVY-infected pepper leaves that were sampled from different locations in Zimbabwe was performed. The PVY genome sequences recovered by de novo assembly of the generated reads were checked for recombination patterns before phylogenetic analyses. Three PVY isolates: d7-Bindura, prime-e5, and q19-Harare were all found to have arisen from a single recombination event involving PVYO and PVYC strains. Phylogenetic analyses provided further evidence of recombination. The isolates in this study were grouped with a pepper-infecting PVY isolate previously found in South Africa. More studies of this kind need to be conducted in Africa to determine the outspread of this particular recombinant virus.
