中文摘要：新德里番茄曲叶病毒（ToLCNDV）是粉虱传双生病毒，可对多种茄科葫芦科栽培植物造成损害。ToLCNDV一直仅限于在亚洲国家发生，直到2012年在西班牙首次报道，可引起瓜类作物严重传染病。本研究显示，在西班牙存在着一个基因一致的ToLCNDV种群，与最近一次传入的ToLCNDV种群共存。世界其他地方报道的ToLCNDV隔离群分析表明，从遗传学角度看这种病毒具有高度异质性群体，没有观察到明显的地理性、植物寄主或年系发育群体。西班牙出现的隔离群属于一个似乎已经重组进化了的种类。该种隔离群似乎适应了侵染瓜类作物，但很少侵染番茄。
外文摘要：Tomato leaf curl New Delhi virus (ToLCNDV) is a whitefly-transmitted bipartite begomovirus (genus Begomovirus, family Geminiviridae) that causes damage to multiple cultivated plant species mainly belonging to the Solanaceae and Cucurbitaceae families. ToLCNDV was limited to Asian countries until 2012, when it was first reported in Spain, causing severe epidemics in cucurbit crops. Here, we show that a genetically-uniform ToLCNDV population is present in Spain, compatible with a recent introduction. Analyses of ToLCNDV isolates reported from other parts of the world indicated that this virus has a highly heterogeneous population genetically with no evident geographical, plant host or year-based phylogenetic groups observed. Isolates emerging in Spain belong to a strain that seems to have evolved by recombination. Isolates of this strain seem adapted to infecting cucurbits, but poorly infect tomatoes.
