Wild plants and weeds growing close to crops constitute a potential reservoir for future epidemies or for the emergence of novel viruses but the frequency and directionality of viral flow between cultivated and wild plants remains poorly documented in many cases. Here, we studied the diversity of viral populations between tomato (Solanum lycopersicum) and neighboring european black nightshade (Solanum nigrum) using high throughput sequencing (HTS) based metagenomics. A large variability in virome richness with only 17.9% shared Operational Taxonomy Units between tomato and nightshade, but this richness could not be linked to a particular host or to local conditions. A detailed population analysis based on assembled contigs for potato virus Y (PVY), broad wilt bean virus 1 and a new ilarvirus tentatively named Solanum nigrum ilarvirus 1 provides information on the circulation of these viruses between these two Solanum species and enriches our knowledge of the tomato virome.

栽培茄和野生茄的病毒串扰的元基因组学分析。

在作物附近生长的野生植物和杂草构成了未来流行病或新型病毒出现的潜在库,但在许多情况下,耕种植物与野生植物之间病毒流动的频率和方向仍然鲜有记载。在这里,我们使用基于高通量测序(HTS)的宏基因组学研究了番茄(Solanum lycopersicum)和邻近的欧洲黑夜茄(Solanum nigrum)之间的病毒种群多样性。番茄和茄属植物之间的病毒丰富度差异很大,只有17.9%共享操作分类单位,但这种丰富度不能与特定寄主或当地条件联系在一起。基于组装的重叠群的马铃薯病毒Y(PVY)的详细人群分析,
