A new polerovirus species with the proposed name faba bean polerovirus 1 (FBPV-1) was found in winter legume crops and weeds in New South Wales, Australia. We describe the complete genome sequence of 5,631 nucleotides, containing all putative open reading frames, from two isolates, one from faba bean (Vicia faba) and one from chickpea (Cicer arietinum). FBPV-1 has a genome organization typical of poleroviruses with six open reading frames. However, recombination analysis strongly supports a recombination event in which the 5' portion of FBPV-1, which encodes for proteins P0, P1 and P1-P2, appears to be from a novel parent with a closest nucleotide identity of only 66% to chickpea chlorotic stunt virus. The 3' portion of FBPV-1 encodes for proteins P3, P4 and P3-P5 and shares 94% nucleotide identity to a turnip yellows virus isolate from Western Australia.
在澳大利亚新南威尔士州的冬季豆类作物和杂草中发现了一种新的马铃薯Y病毒属病毒，暂定名为蚕豆马铃薯Y病毒1（FBPV-1）。我们描述了来自两个分离株（一个来自蚕豆（Vicia faba），另一个来自鹰嘴豆（Cicer arietinum））的5631个核苷酸的完整基因组序列，其中包含所有推定的开放阅读框。FBPV-1具有马铃薯Y病毒属典型的基因组结构，有六个开放阅读框。然而，重组分析有力地支持了一次重组事件，其中FBPV-1编码蛋白P0、P1和P1-P2的5'部分似乎来自一个新的亲本，与鹰嘴豆褪绿矮缩病毒的核苷酸同一性仅为66%。FBPV-1的3'部分编码蛋白P3、P4和P3-P5，与来自西澳大利亚的芜菁黄化病毒分离株的核苷酸同一性为94%。
