Abstract
While conducting field trial of 82 genotypes of bottle gourd at Delhi during 2020-2021, a particular genotype, IC-0262269 was found to be affected by chlorotic curly stunt disease (CCSD). The affected plants were severely stunted and bearing very small chlorotic and crinkle leaves. The disease incidence in the said genotype was as high as 80% among different replicated trial blocks. The application of PCR using a generic primers specific to begomoviruses, as well as species-specific PCR diagnostics to six tomato-infecting begomoviruses: tomato leaf curl New Delhi virus (ToLCNDV), tomato leaf curl Palampur virus (ToLCPalV), tomato leaf curl Joydebpur virus (ToLCJoV), tomato leaf curl Gujrat virus (ToLCGuV), tomato leaf curl Bangalore virus (ToLCBV), and chilli leaf curl virus (ChiLCV) showed that, only ToLCPalV could be detected in the genotype IC-0262269. Following, rolling circle amplification, cloning and sequencing of full-length DNA-A and DNA-B genome of an isolate BoG1-ND from the genotype IC-0262269 revealed association of ToLCPalV with the disease. The successful agro-infection of the cloned genome of BoG1-ND (DNA-A and DNA-B) in the plants of Nicotiana benthamiana and bottle gourd demonstrated that ToLCPalV is the causal begomovirus of CCSD. The study provides the first evidence of the natural occurrence of ToLCPalV in bottle gourd crop and also showed that the bottle gourd genotype IC-0262269 is super-susceptible to ToLCPalV.

Virusdisease 2023; 34:421-430. [PMID: 37780909 PMCID: PMC10533461 DOI: 10.1007/s13337-023-00837-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 08/21/2023] [Indexed: 10/03/2023] Open
Abstract
Cucurbits are an essential summer-season vegetable crops, but they are highly vulnerable from a range of abiotic and biotic factors. One of the significant biotic factors posing a growing menace to the production of major cucurbits in India is the emergence of tomato-infecting begomoviruses. In this study, we utilized PCR-based species-specific primers, developed earlier in our laboratory for the detection of begomoviruses infecting tomato and chilli plants, to identify begomoviruses in cucurbits across various regions of India. Leaf samples from major cucurbits were collected from different regions of Haryana, Delhi, Uttar Pradesh, Chhattisgarh, Maharashtra, Telangana and Karnataka, during the year 2020-2021. Total nucleic acid (TNA) was extracted from the samples and subjected to PCR using a generic primer specific to begomoviruses. The samples that exhibited positive amplification were further tested using six different species-specific primers targeting specific begomovirus species, namely Tomato leaf curl New Delhi virus (ToLCNDV), Tomato leaf curl Palampur virus (ToLCPalV), Tomato leaf curl Bangalore virus (ToLCBV), Tomato leaf curl Joydebpur virus (ToLCJoV), Tomato leaf curl Gujarat virus (ToLCGuV), and Chilli leaf curl virus (ChiLCV). The PCR analysis revealed that among the 551 plant samples tested, a total of 124 samples exhibited positive amplification using the universal begomovirus PCR. Specifically, 47 samples tested positive for ToLCNDV, 73 samples were positive for ToLCPalV and only one sample showed positive amplification for ChiLCV. However, none of the samples tested positive for ToLCJoV, ToLCGuV and ToLCBV. These findings from our study indicate the prevalence of ToLCNDV and ToLCPalV in major cucurbits across India. Furthermore, the study highlights the varied distribution of begomoviruses in major cucurbits between northern and southern regions of India.

Detecting Tomato Leaf Curl New Delhi Virus Causing Ridge Gourd Yellow Mosaic Disease, and Other Begomoviruses by Antibody-Based Methods. PLANTS (BASEL, SWITZERLAND) 2023; 12:490. [PMID: 36771575 PMCID: PMC9919216 DOI: 10.3390/plants12030490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/03/2023] [Accepted: 01/17/2023] [Indexed: 06/18/2023]
Abstract
The incidence and severity of begomovirus diseases have been increasing around the world recently, and the ridge gourd [Luffa acutangula (Roxb.) L.] is the latest example of a crop that has become highly susceptible to the outbreak of the tomato leaf curl New Delhi virus (ToLCNDV, genus Begomovirus) in India. Accurate diagnosis of causal agents is important in designing disease management strategies. In this study the coat protein (CP) gene from a ToLCNDV-Rg ridge gourd isolate was used to produce polyclonal antibodies (ToLCNDV-Rg-CP-PAb) in a rabbit. The antibodies successfully detected a 30.5 kDa ToLCNDV-Rg-CP in extracts of symptomatic ridge gourd leaf samples by several assays, such as Western Blotting (WB), Dot Immuno Binding Assay (DIBA), Direct Antigen Coating Enzyme Linked Immuno Sorbent Assay (DAC-ELISA), Immuno Capture Polymerase Chain Reaction (IC-PCR), and Immuno Capture Loop-Mediated Isothermal Amplification (IC-LAMP) assays. However, none of the negative samples tested positive in either of the detection methods. Among all the methods tested, the immunocapture assay, IC-LAMP, was the most sensitive in detecting ToLCNDV-Rg. Furthermore, antibodies generated in this study also detected other commonly occurring begomoviruses in South India, such as tomato leaf curl Palampur virus and squash leaf curl China virus in cucurbits. Together, ToLCNDV-Rg-CP-PAb can be used for detecting at least three species of begomoviruses infecting cucurbits. The obtained antibodies will contribute to monitoring disease outbreaks in multiple crops.

Abstract
Summer squash is one of the important vegetable crops and its production is hampered by various abiotic and biotic stresses. Of the different biotic stresses, viral infections are responsible for causing great losses to this crop. Diseases caused by begomoviruses are becoming a major constraint in the cultivation of summer squash. Samples from summer squash plants exhibiting severe yellow mosaic and leaf curl symptoms were collected from the Varanasi district of Uttar Pradesh (India) and begomovirus associated with these plants was transmitted through whiteflies (Bemisia tabaci) to healthy squash plants. The relationship between causal virus and whitefly vector was determined. The minimum acquisition access period (AAP) and inoculation feeding period (IFP) required by B. tabaci to transmit the virus was determined to be 10 min and female insects have greater efficiency in transmitting virus than male insects. The partial genome of the virus was amplified by PCR (1.2 kb), cloned and sequenced from the ten infected plant samples collected from field. Partial genome sequence analysis (1.2 kb) obtained from the ten samples revealed that they are associated with begomovirus species closely related to the Indian strain of Squash leaf curl China virus (SLCCNV). Therefore, one representative sample (Sq-1) was selected and complete genome of the virus was amplified by rolling circle amplification (RCA) method. Sequence analysis by Sequence Demarcation Tool (SDT) showed that the current isolate has maximum nucleotide (nt) identity of 93.7-98.4% and 89-98.1% with respect to DNA A DNA B, respectively with Indian strains of SLCCNV infecting cucurbits in India. Recombination analysis of genomes (DNA A and DNA B components) showed that a major part of genomes likely to be originated from already known begomoviruses (ToLCNDV, SLCCNV-CN and SLCCNV-IN) are infecting cucurbitaceous crops. Serological assays such as triple antibody sandwich-enzyme-linked immune-sorbent (TAS-ELISA) assay, dot blot immunobinding assay (DIBA), immuno-capture polymerase chain reaction (IC-PCR) were developed for the detection of SLCCNV.

Characterization of Tomato leaf curl New Delhi virus associated with leaf curl and yellowing disease of Watermelon and development of LAMP assay for its detection. 3 Biotech 2020; 10:282. [PMID: 32550101 DOI: 10.1007/s13205-020-02245-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Accepted: 05/04/2020] [Indexed: 12/19/2022] Open
Abstract
Diseases caused by begomoviruses are becoming the major limiting factors for the production of watermelon in India. Survey for the incidence of plants showing symptoms typical to begomovirus infection was conducted in watermelon fields. The study revealed that 40% of the watermelon plants were showing the yellowing and downward curling symptoms. Twenty infected samples were collected from the different farmer's fields to know the association of begomoviruses. The PCR amplification using begomovirus-specific primers resulted in an expected 1.2 kb PCR product indicating the begomovirus association with the watermelon samples. The sequence comparison results of 1.2 kb representing partial genome revealed that all sequences obtained from watermelon samples have a nucleotide (nt) identity of more than 98% among them and are maximum homology with Tomato leaf curl New Delhi virus (ToLCNDV). One watermelon sample (WM1) was selected for complete genome amplification using RCA method (rolling-circle amplification). Amplification of DNA B and no amplification of betasatellites and alphasatellite indicated this virus as bipartite. Sequence Demarcation Tool (SDT) analysis of the DNA A component of the WM1 isolate showed the maximum nt identity of 94.6-97.9% and 85.2-95.8% with ToLCNDV infecting cucurbits. The recombinant analysis showed that the genome was likely to be derived from the recombination of already reported begomoviruses (ToLCNDV, ToLCPalV, and MYMIV) infecting diverse crops. The whitefly cryptic species predominant in the begomovirus-infected watermelon fields were identified as Asia-II-5 group. The LAMP assay developed based on coat protein gene sequence was able to detect the ToLCNDV in the infected samples. Visual detection of the LAMP-amplified products was observed with the hydroxy naphthol blue. LAMP assay was also validated with ToLCNDV infected sponge gourd, spine gourd, ivy gourd, ridge gourd, and cucumber. This is the first report of ToLCNDV association with leaf curl and yellowing disease of watermelon from India and World based on complete genome sequencing.

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.
