Abstract

New recombinant of Tomato leaf curl New Delhi virus infecting melon in Indonesia.

Abstract

The complete nucleotide sequence of Tomato leaf curl New Delhi virus detected from melon in Indonesia-[Indonesia:Yogya:Melon:2015] (ToLCNDV-[ID:YG:Mel:15]) was determined. ToLCNDV-[ID:YG:Mel:15] has bipartite DNAs, and both DNAs showed highest identity to ToLCNDV-[Indonesia:Java:Cucumber:2008] (ToLCNDV-[ID:JV:Cuc:08]). However in a phylogenetic analysis based on AV1, ToLCNDV-[ID:YG:Mel:15] clustered with Squash leaf curl China virus (SLCCNV) isolates. Recombination analyses revealed that ToLCNDV-[ID:YG:Mel:15] is a recombinant between ToLCNDV and SLCCNV. Thus, the virus is a new recombinant of ToLCNDV. The infectivity of the recombinant ToLCNDV-[ID:YG:Mel:15] isolate was confirmed, and the inoculation induced mosaic on melon, but not on tomato, the primary natural host of ToLCNDV.
