摘要：

In Tunisia, potato virus Y (PVY) causes yield losses, particularly on pepper cultures. Sequence analysis from the 3'non-translated region (3'-NTR) and from the coat protein coding region (CP) of 2 PVY isolates from pepper and 1 from potato are in agreement with the biological classification. Potential RNA secondary structure analysis of the 3'-NTR region revealed additional differences between isolates. Phylogenetic analysis of these 3 sequences suggests that 1 isolate (PVY-P21) might have emerged through a recombination process.
