The family Apiaceae comprises approximately 3700 species of herbaceous plants, including important crops, aromatic herbs and field weeds. Here we report a study of 10 preserved historical or recent virus samples of apiaceous plants collected in the United Kingdom (UK) import interceptions from the Mediterranean region (Egypt, Israel and Cyprus) or during surveys of Australian apiaceous crops. Seven complete new genomic sequences and one partial sequence, of the apiaceous potyviruses apium virus Y (ApVY), carrot thin leaf virus (CaTLV), carrot virus Y (CarVY) and celery mosaic virus (CeMV) were obtained. When these 7 and 16 earlier complete non-recombinant apiaceous potyvirus sequences were subjected to phylogenetic analyses, they split into 2 separate lineages: 1 containing ApVY, CeMV, CarVY and panax virus Y and the other CaTLV, ashitabi mosaic virus and konjac virus Y. Preliminary dating analysis suggested the CarVY population first diverged from CeMV and ApVY in the 17th century and CeMV from ApVY in the 18th century. They also showed the "time to most recent common ancestor" of the sampled populations to be more recent: 1997 CE, 1983 CE and 1958 CE for CarVY, CeMV and ApVY, respectively. In addition, we found a new family record for beet western yellows virus in coriander from Cyprus; a new country record for carrot torradovirus-1 and a tentative novel member of genus as a co-infection in a carrot sample from Australia; and a novel member of the genus recovered from a sample of herb parsley from Israel.
伞形科包含约3700种草本植物，包括重要作物、芳香草本植物和田间杂草。在此，我们报告了一项对10个保存的历史或近期伞形科植物病毒样本的研究，这些样本是在英国从地中海地区（埃及、以色列和塞浦路斯）的进口拦截中或在澳大利亚伞形科作物调查期间收集的。获得了伞形科马铃薯Y病毒芹菜病毒Y（ApVY）、胡萝卜细叶病毒（CaTLV）、胡萝卜病毒Y（CarVY）和芹菜花叶病毒（CeMV）的7个完整新基因组序列和1个部分序列。当将这7个以及之前的16个完整的非重组伞形科马铃薯Y病毒序列进行系统发育分析时，它们分为2个不同的谱系：1个包含ApVY、CeMV、CarVY和人参病毒Y，另一个包含CaTLV、明日叶花叶病毒和魔芋病毒Y。初步年代分析表明，CarVY群体在17世纪首次与CeMV和ApVY分化，CeMV在18世纪与ApVY分化。它们还显示，抽样群体的“最近共同祖先时间”更近：CarVY、CeMV和ApVY分别为公元1997年、公元1983年和公元1958年。此外，我们在来自塞浦路斯的香菜中发现了甜菜西方黄化病毒的一个新的科记录；在来自澳大利亚的一个胡萝卜样本中发现了胡萝卜托拉多病毒-1的一个新的国家记录以及作为共感染的一个暂定新属成员；并且从来自以色列的药芹样本中分离出一个新的属成员。
