A Novel Strain of Tomato Leaf Curl New Delhi Virus Has Spread to the Mediterranean Basin

Tomato leaf curl New Delhi virus (ToLCNDV) is a whitefly-transmitted bipartite begomovirus (genus , family ) that causes damage to multiple cultivated plant species mainly belonging to the and families. ToLCNDV was limited to Asian countries until 2012, when it was first reported in Spain, causing s...

Description
Summary:Tomato leaf curl New Delhi virus (ToLCNDV) is a whitefly-transmitted bipartite begomovirus (genus , family ) that causes damage to multiple cultivated plant species mainly belonging to the and 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.
