Other claims from this paper (10)
- Observation Leaf curl disease in potato is caused by a strain of Tomato leaf curl New Delhi virus (ToLCNDV).
- Intervention effect The begomovirus from a severely affected potato plant, sap-transmitted to Nicotiana benthamiana seedlings, induced severe leaf distortion and stunting 15 days after inoculation.
- Observation Viral replicative DNA clones at the XbaI and PstI sites carried a unit genome length insert of about 2.7 kb that hybridized with the viral replicative forms from infected plants.
- Observation The nucleotide sequence of the XbaI and PstI clones corresponded to DNA A and B components of the begomovirus causing the disease.
- Observation DNA A has 93–95% nucleotide identity with ToLCNDV isolates.
- Observation DNA A has less than 75% nucleotide identity with other Tomato leaf curl virus isolates and Potato yellow mosaic virus.
- Observation This is the first observation of a begomovirus causing a severe disease of potato in India.
- Observation The sequence data indicate the cause is a virus closely related to ToLCNDV that, unlike the strain infecting potato, is not sap-transmissible.
- Observation A new strain of ToLCNDV has likely emerged that infects a new host, potato.
- Mechanism Earlier planting of potato crops may have led to a build-up of whitefly populations and the emergence of a new disease in potato.
