“…2). The BV1 N terminal sequence of SL-1 was 28 and 13 amino acids shorter than the BV1 ORFs of two nonmechanically transmissible isolates, ToLCNDV-Cuc and ToLCNDV-Svr (Samretwanich et al 2000b;Hussain et al 2005) but equivalent in length to those of a mechanically transmissible isolate ToLCNDV-Pot (Usharani et al 2004). …”

“…Several new disease reports revealed that ToLCNDV caused severe symptoms on bitter gourd (Tahir and Haider 2005), bottle gourd (Ito et al 2008), cantaloupe (Samretwanich et al 2000a), cucumber (Samretwanich et al 2000b), muskmelon (Samretwanich et al 2000d), watermelon (Mansoor et al 2000), and wax gourd (Samretwanich et al 2000c), in Thailand or Pakistan. Most ToLCNDV isolates were only transmitted by whiteflies naturally while only the potato isolate has been shown to be mechanically transmitted to its original host (Usharani et al 2004).…”

Oriental melon plants, Cucumis melo var. makuwa cv. Silver Light, showing virus-induced symptoms of mosaic, leaf curl and puckering were observed in the fields of eastern Taiwan in 2007. A virus culture, designated as SL-1, isolated from the diseased melon was established in systemic host plants, Nicotiana benthamiana and oriental melon, by mechanical inoculation. SL-1 did not react to the antisera against common cucurbit-infecting RNA viruses. Viral DNAs extracted from the diseased plant were amplified with the degenerate primers for begomoviruses. The full-length genomic DNA-A and DNA-B of SL-1 were sequenced and found to be closest, with 97.7% and 90.6% nucleotide identity, respectively, to Tomato leaf curl New Delhi begomovirus (ToLCNDV) cucumber isolate from a group of cucurbit-infecting begomoviruses. The virus SL-1 was designated as ToLCNDV oriental melon isolate (ToLCNDV-OM). The pathogenicity of ToLCNDV-OM was confirmed by agroinfection. Progeny virus from the agroinfected N. benthamiana plants was able to infect oriental melon by mechanical inoculation and caused symptoms similar to the original diseased melon in the field. The ToLCNDV-OM also infected five other species of cucurbitaceous plants by mechanical inoculation. This is the first report of a new ToLCNDV isolate causing severe disease on oriental melon in Taiwan

“…It was reported for the first time in India from tomato and further its infectivity study demonstrated that both DNA-A and DNA-B are essential for symptom development [10]. ToLCNDV is known to infect tomato in India since nearly two decades, but during the last one decade, its host range has increased enormously to various crops such as potato [21], papaya [12], eggplant [11] okra [23] and several cucurbitaceous vegetables like bottle gourd, bitter gourd, cucumber, ivy gourd, long melon, pumpkin, ridge gourd and watermelon in northern India and chayote in north-western India [7,16,17,20]. In Pakistan, besides tomato, ToLCNDV was also reported on crops like chilli [5], bitter gourd [18], and on weed Eclipta prostrata [3].…”

“…Tomato leaf curl New Delhi virus (ToLCNDV) is an Old World begomovirus that induces leaf curling and yellowing in tomato (Lycopersicon esculentum) and has also been detected on cucurbits, chilies, and potato on the Indian subcontinent (16,20,21,25,36). ToLCNDV is a bipartite virus that requires DNA B for symptom development, and the coat protein is dispensable for systemic infection and symptom development (25).…”

Geminiviruses are single-stranded DNA viruses that infect a broad range of dicotyledonous and monocotyledonous plants. Viruses of the family Geminiviridae have been classified into four genera based on host range and genome organization (30). Of these, the whitefly-transmitted geminiviruses (genus Begomovirus) are the largest group, with more than 100 virus species identified so far (8). Geminiviruses replicate in the nuclei of host cells by a rolling-circle replication mechanism (reviewed in reference 11). For the propagation of infection in the host, these viruses encode movement proteins that direct the viral genome to the cortical cytoplasm and across the barrier of the cell wall. For bipartite begomoviruses, this process requires two proteins, encoded by the component designated DNA B: the nuclear shuttle protein (NSP) and the cell-to-cell movement protein (MP). These proteins act cooperatively to move the viral DNA from its site of replication in the nucleus to the cytoplasm and into adjacent plant cells (32).The geminivirus MP and NSP recognize DNA in a form-and size-specific manner (12,29). The NSP shuttles newly replicated viral DNA between the nucleus and the cytoplasm (42). MP traps these NSP-viral DNA complexes in the cytoplasm and redirects them to and across the plant cell wall (24,43). In adjacent cells, the NSP-viral DNA complexes are released, and NSP targets the viral DNA to the nucleus to initiate new rounds of infection. This process of movement is highly regulated. Recently, an acetyltransferase has been isolated from Arabidopsis thaliana that interacts with the NSP encoded by the bipartite begomovirus Cabbage leaf curl virus (22). This protein regulates the nuclear export of the viral DNA and is highly conserved in plants.
