Abstract
Nucleotide sequence of complete genome of a new isolate (KAN-6) of tomato leaf curl New Delhi virus (ToLCNDV) from Kanpur, Uttar Pradesh, India was determined. Sequence analysis indicated that it shared maximum identity to ToLCNDV isolates from pumpkin and ashgourd. Infectious clones of isolate KAN-6 along with two other ToLCNDV isolates (MOD-21 & FAI-19) obtained from potato fields of Modipuram and Faizabad, India were produced and used in symptom expression studies in N. benthamiana and potato plants through agro-inoculation. These isolates produced different symptoms both in N. benthamiana and potato. Severe symptoms of yellow mottling, downward curling and stunted growth were observed in N. benthamiana plants inoculated with KAN-6. MOD-21-inoculated plants also showed downward curling, stunted growth, but yellow mottling was observed only in older leaves whereas FAI-19-inoculated plants produced only downward curling symptoms. In case of potato, typical symptoms of apical leaf curl disease were observed in cultivar Kufri Pukhraj inoculated with MOD-21 and KAN-6 that are similar to those produced by virus-infected plants in the field. However, MOD-21 produced more prominent yellow mosaic symptoms as compared to KAN-6. FAI-19 produced only restricted yellow spots in Kufri Pukhraj. Only mild symptoms appeared in KAN-6 and no symptoms were observed in MOD-21- and FAI-19-inoculated Kufri Bahar plants which is known to show lowest seed degeneration under field conditions. Analysis of genomic components indicated that these isolates had 94.8-94.9% and 87.9-97.3% identity among them in DNA A and DNA B, respectively. The results of the study indicate the association of ToLCNDV isolates of different symptomatology with apical leaf curl disease of potato. This is also a first experimental demonstration of Koch's postulate for a begomovirus associated with apical leaf curl disease of potato.Author names: Please confirm if the author names (Swarup Kumar Chakrabarti) are presented accurately and in the correct sequence (given name, middle name/initial, family name).Yes.

Virusdisease 2017; 28:425-429.

Abstract
During 2012-2014, mosaic disease on chayote in the farmers field of Kodaikanal region (high altitude zone) of Tamil Nadu was observed. The disease was characterized with severe mosaic, cupping and enation on leaves with reduced fruit size. Disease was found to causes an yield loss of more than 60% with the maximum disease incidence of 100% for the past 5 years consecutively. Preliminary serological and molecular screening indicated the association of begomovirus with the disease. Complete nucleotide sequence and phylogenetic analysis of DNA A revealed the identity of the virus as tomato leaf curl New Delhi virus (ToLCNDV). In recombination analysis study, the major parent was identified as ToLCNDV from Pakistan infecting tomato. Thus the present finding confirms expansion of new geographical region and host for ToLCNDV causing mosaic disease on chayote from Tamil Nadu. To our knowledge this is the first confirmed report for the occurrence of ToLCNDV on chayote in southern India.

Abstract
The tomato leaf curl New Delhi virus (ToLCNDV) (genus Begomovirus, family Geminiviridae) represents an important constraint to tomato production, as it causes the most predominant and economically important disease affecting tomato in the Indian sub-continent. However, in recent years, ToLCNDV has been fast extending its host range and spreading to new geographical regions, including the Middle East and the western Mediterranean Basin. Extensive research on the genome structure, protein functions, molecular biology, and plant-virus interactions of ToLCNDV has been conducted in the last decade. Special emphasis has been given to gene silencing suppression ability in order to counteract host plant defense responses. The importance of the interaction with DNA alphasatellites and betasatellites in the biology of the virus has been demonstrated. ToLCNDV genetic variability has been analyzed, providing new insights into the taxonomy, host adaptation, and evolution of this virus. Recombination and pseudorecombination have been shown as motors of diversification and adaptive evolution. Important progress has also been made in control strategies to reduce disease damage. This review highlights these various achievements in the context of the previous knowledge of begomoviruses and their interactions with plants.

Survey, symptomatology, transmission, host range and characterization of begomovirus associated with yellow mosaic disease of ridge gourd in southern India. Virusdisease 2017; 28:146-155.

Abstract
Ridge gourd is an important vegetable crop and is affected by several biotic and abiotic factors. Among the different biotic factors, ridge gourd yellow mosaic disease (RgYMD) is new emerging threat for the production of ridge gourd. The incidence of the RgYMD varied from 30 to 100% in southern India with highest disease incidence of 100% observed in Belagavi district of Karnataka state. The infected plants showed chlorosis, mosaic, cupping of leaves, blistering, reduction in leaf size and stunted growth. The varieties/hybrids grown in the farmer's fields were found to be susceptible to the disease. Begomovirus was detected in 61 out 64 samples collected from different areas of southern India. Further, all the samples failed to give amplification for beta and alpha satellites. The transmission studies revealed that single whitefly (Bemisia tabaci) is enough to transmit the virus, however, 100% transmission was observed with 10 whiteflies. The minimum acquisition access period and inoculation access period for transmission of virus by whitefly was 15 min. Among the 56 host plants belonging to diversified families tested for host range, sponge gourd, ash gourd, bottle gourd, pumpkin, cucumber, summer squash, cluster bean, tobacco and datura were shown to be susceptible. Seventy six varieties/hybrids evaluated for identifying the resistance source for RgYMD, all were found highly susceptible. Sequence analysis of DNA-A revealed that the causal virus shared highest nucleotide sequence identity (92.3%) with Tomato leaf curl New Delhi virus (ToLCNDV) infecting sponge gourd from northern India. Sequence and phylogenetic analysis of both DNA-A and DNA-B components showed that the begomovirus associated with RgYMD is found to be strain of ToLCNDV. This is first report of ToLCNDV association with RgYMD from southern India.

Abstract
Cotton leaf curl disease (CLCuD) is the major biotic constraint to cotton production on the Indian subcontinent, and is caused by monopartite begomoviruses accompanied by a specific DNA satellite, Cotton leaf curl Multan betasatellite (CLCuMB). Since the breakdown of resistance against CLCuD in 2001/2002, only one virus, the "Burewala" strain of Cotton leaf curl Kokhran virus (CLCuKoV-Bur), and a recombinant form of CLCuMB have consistently been identified in cotton across the major cotton growing areas of Pakistan. Unusually a bipartite isolate of the begomovirus Tomato leaf curl virus was identified in CLCuD-affected cotton recently. In the study described here we isolated the bipartite begomovirus Tomato leaf curl New Delhi virus (ToLCNDV) from CLCuD-affected cotton. To assess the frequency and geographic occurrence of ToLCNDV in cotton, CLCuD-symptomatic cotton plants were collected from across the Punjab and Sindh provinces between 2013 and 2015. Analysis of the plants by diagnostic PCR showed the presence of CLCuKoV-Bur in all 31 plants examined and ToLCNDV in 20 of the samples. Additionally, a quantitative real-time PCR analysis of the levels of the two viruses in co-infected plants suggests that coinfection of ToLCNDV with the CLCuKoV-Bur/CLCuMB complex leads to an increase in the levels of CLCuMB, which encodes the major pathogenicity (symptom) determinant of the complex. The significance of these results are discussed.

Abstract
Leaf samples of Solanum lycopersicum, Capsicum annuum, Cucurbita moschata, Cucurbita pepo, Sechium edule and Erythrina spp. were collected. All samples were positive for begomoviruses using polymerase chain reaction and degenerate primers. A sequence of ∼1,100 bp was obtained from the genomic component DNA-A of 14 samples. In addition, one sequence of ∼580 bp corresponding to the coat protein (AV1) was obtained from a chayote (S. edule) leaf sample. The presence of Squash yellow mild mottle virus (SYMMoV) and Pepper golden mosaic virus (PepGMV) were confirmed. The host range reported for SYMMoV includes species of the Cucurbitaceae, Caricaceae and Fabaceae families. This report extends the host range of SYMMoV to include the Solanaceae family, and extends the host range of PepGMV to include C. moschata, C. pepo and the Fabaceae Erythrina spp. This is the first report of a begomovirus (PepGMV) infecting chayote in the Western Hemisphere.
