An isolate of the Andean strain of potato virus S (PVS), named BB-AND, was detected for the first time in a Brazilian potato crop, fully sequenced and analyzed. A comparison of BB-AND with other PVS isolates (Andean and Ordinary) showed that BB-AND is quite distinct. The lowest amino acid sequence identity to the only other fully sequenced Andean isolate was found in ORF 1 (82%) and ORF 6 (87%). Recombination analysis showed that the isolate Vltava (AJ863510), from Germany, is a recombinant between PVS(O) and PVS(A) isolates, with the recombination event located between nucleotides 6125 and 8324.
首次在巴西马铃薯作物中检测到安第斯马铃薯 Y 病毒 S（PVS）的安第斯菌株分离物 BB-AND，对其进行了全序列测定和分析。将 BB-AND 与其他 PVS 分离物（安第斯和普通）进行比较表明，BB-AND 非常独特。与唯一全序列测序的安第斯分离物相比，ORF1（82%）和 ORF6（87%）的氨基酸序列同一性最低。重组分析表明，来自德国的分离物 Vltava（AJ863510）是 PVS（O）和 PVS（A）分离物之间的重组体，重组事件发生在核苷酸 6125 和 8324 之间。
