ABTRACT
A new potexvirus affecting ornamental allium spp in the Netherlands was identified and characterized at the molecular level. The virus had a single-stranded RNA genome of 7100 bp (excluding the 18 bp poly A tail). The genome organization was found to be typical of members of the genus Potexvirus and consisted of five open reading frames (ORF). Nucleotide and amino acid sequence comparisons with those of known potexvirus members showed that this virus is related to Hosta virus X and Hydrangea ringspot virus. Sequence similarities and phylogenetic relationships suggested that the allium virus is a new and distinct species in the genus Potexvirus and the name, Allium virus X (AlVX) is proposed.
摘要
在荷兰，一种新的影响观赏葱属植物的马铃薯 Y 病毒被鉴定和从分子水平上进行了特征描述。该病毒的基因组是单链 RNA，长度为 7100 个碱基（不包括 18 个碱基的 poly A 尾）。基因组组织与马铃薯 Y 病毒属的成员的典型特征一致，由五个开放阅读框（ORF）组成。与已知的马铃薯 Y 病毒属成员的核苷酸和氨基酸序列比较表明，该病毒与萱草斑驳病毒和绣球花环斑病毒有关。序列相似性和系统发育关系表明，该葱属病毒是马铃薯 Y 病毒属中的一个新的独特种，建议命名为葱属 X 病毒（AlVX）。
