Abstract
BACKGROUND Tomato (Solanum lycopersicum L.) is an economically important vegetable crop around the globe. Tomato yellow leaf curling (TYLC) is the most devastating viral disease posing a serious threat to tomato production throughout the tropical and subtropical world. Induction of microbe-mediated systemic resistance in plants has been of great interest in recent years as a novel microbiological tool in disease and insect pest management. This in-vitro study aimed to determine the effectiveness of different strains (BB252, BB72 and ARSEF-2860) of a hypocreal fungus Beauveria bassiana against TYLCV disease and aphid Myzus persicae. Potted tomato plants exogenously treated with conidial and filtrate suspensions of B. bassiana strains and of their partially purified or purified proteins were exposed to TYLCV inoculum and aphid M. persicae. RESULTS Results showed a significant suppression of TYLCV disease severity index by the exogenous application of conidial, filtrate and protein treatments of all B. bassiana strains and this response was directly proportional to the treatment concentration. Similarly, mean fecundity rate of M. persicae was also significantly reduced by the highest concentration of ARSEF-2860-derived elicitor protein PeBb1, followed by the highest concentrations of BB252- and BB72-derived partially purified proteins. Moreover, these B. bassiana-derived proteins also caused a significant upregulation of most of the plant immune marker genes associated with plant defense. CONCLUSION Overall, the study findings suggest that these B. bassiana strains and their partially purified or purified elicitor proteins could be effective biological tools for the management of TYLCV and aphid infestation on tomato plants. © 2023 Society of Chemical Industry.

Abstract
BACKGROUND Fenugreek (Trigonella foenum-graecum L.) is an annual medicinal and spice crop belonging to the family Fabaceae. The occurrence of a yellow vein disease was recorded in fenugreek in Jodhpur (India) in 2022. The infection of begomoviruses in legume crops results in significant yield loss and major economic loss. The current study reports an association of a novel begomovirus species associated with yellow vein disease in Fenugreek. METHODS AND RESULTS In symptomatic fenugreek plants, geminivirus-like particles were visible under a transmission electron microscope. Further, nucleotide sequence analysis of the rolling circle amplified product revealed 2743 nucleotide DNA-A genome with close relatedness to French bean leaf curl virus (88.21%) and Senna leaf curl virus (87.63%). It was proposed as a new begomovirus species, Fenugreek yellow vein Rajasthan virus. The genome organization suggested the presence of a typical nonanucleotide sequence along with 7 ORFs in DNA-A. A possible recombination event took place in the coat protein (V1) region with Pedilanthus leaf curl virus and Chilli leaf curl virus as major and minor parents. The recombinant virus poses possible threats to several other legume crops. To the best of our knowledge, this is the first report of the association of FeYVRaV with fenugreek yellow vein disease from northwestern India. CONCLUSIONS In conclusion, the presence of a novel begomovirus species associated with yellow vein disease in fenugreek is alarming and needs further studies on its infectivity to prevent its spread to legume crops.

Abstract
BACKGROUND Alphasatellites are small coding DNA satellites frequently associated with a begomovirus/betasatellite complex, where they are known to modulate virulence and symptom development. Two distinct alphasatellites, namely, Cotton leaf curl Multan alphasatellite (CLCuMuA), and Gossypium darwinii symptomless alphasatellite (GDarSLA) associated with Cotton leaf curl Multan virus-India (CLCuMuV-IN) and Ludwigia leaf distortion betasatellite (LuLDB) were found to be associated with yellow mosaic disease of hollyhock (Alcea rosea) plants. In this study, we show that alphasatellites CLCuMuA and GDarSLA attenuate and delay symptom development in Nicotiana benthamiana. The presence of either alphasatellites reduce the accumulation of the helper virus CLCuMuV-IN. However, the levels of the associated betasatellite, LuLDB, remains unchanged. These results suggest that the alphasatellites could contribute to the host defence and understanding their role in disease development is important for developing resistance strategies. METHODS Tandem repeat constructs of two distinct alphasatellites, namely, CLCuMuA and GDarSLA associated with CLCuMuV-IN and LuLDB were generated. N. benthamiana plants were co-agroinoculated with CLCuMuV and its associated alphasatellites and betasatellite molecules and samples were collected at 7, 14 and 21 days post inoculation (dpi). The viral DNA molecules were quantified in N. benthamiana plants by qPCR. The sequences were analysed using the MEGA-X tool, and a phylogenetic tree was generated. Genetic diversity among the CLCuMuA and GDarSLA was analysed using the DnaSP tool. RESULTS We observed a reduction in symptom severity and accumulation of helper virus in the presence of two alphasatellites isolated from naturally infected hollyhock plants. However, no reduction in the accumulation of betasatellite was observed. The phylogenetic and genetic variability study revealed the evolutionary dynamics of these distinct alphasatellites , which could explain the role of hollyhock-associated alphasatellites in plants. CONCLUSIONS This study provides evidence that alphasatellites have a role in symptom modulation and suppress helper virus replication without any discernible effect on the replication of the associated betasatellite.

Abstract
Hollyhock (Alcea rosea, family Malvaceae) is an ornamental plant grown widely in gardens across South Asia. In a bed of ornamental plants near the village of Chakri (Punjab Province, Pakistan) in 2014, hollyhock plants showing two distinct symptom types were identified: yellow vein mosaic and leaf crumple. PCR amplification with universal primers amplified a begomovirus from separate nucleic acid extracts of single plants of each type but amplified a betasatellite only from the plant with the yellow vein mosaic symptoms. No potential begomovirus DNA B component or alphasatellite could be identified in either sample. After cloning, the genome sequences of two viruses, one from a plant of each symptom type, were determined and shown to share 99.9% nucleotide sequence identity with each other but less than 91% nucleotide sequence identity with all previously characterized begomoviruses, with the highest identity (90%) to an isolate of pedilanthus leaf curl virus (PeLCV). This indicates that the two hollyhock plants were infected with a newly identified begomovirus for which the name "hollyhock vein yellowing virus" (HoVYV) is proposed. HoVYV likely has a recombinant origin. The betasatellite showed the highest nucleotide sequence identity to an isolate of cotton leaf curl Multan betasatellite (CLCuMuB), a betasatellite associated with cotton leaf curl disease across Pakistan and northwestern India. These findings add to the diversity of known begomoviruses in South Asia and again highlight the role of hollyhock as a reservoir of the cotton leaf curl begomovirus betasatellite complex. The results also suggest that the yellow vein mosaic symptoms in hollyhock are due to the betasatellite rather than the virus.

Abstract
In India, begomovirus infection causing tomato leaf curl disease (ToLCD) is a major constraint for tomato productivity. Here, we have identified two distinct monopartite begomovirus and betasatellite complexes causing ToLCD in the western part of India. A new monopartite begomovirus (Tomato leaf curl Mumbai virus, ToLCMumV) and betasatellite (Tomato leaf curl Mumbai betasatellite, ToLCMumB) were isolated from the Mumbai sample. A distinct Tomato leaf curl Gandhinagar virus (ToLCGanV) and Tomato leaf curl Gandhinagar betasatellite (ToLCGanB) were identified from the Gandhinagar sample. Both of the cloned begomoviruses were recombinants. The demonstration of systemic infection caused by begomovirus (ToLCGanV or ToLCMumV) alone in N. benthamiana and tomato (a virus resistant variety) emphasizes that they were monopartite begomoviruses. Co-inoculation of cognate begomovirus and betasatellite reduces the incubation period and increases symptom severity. Thus, Koch's postulates were satisfied for these virus complexes. Further, an enhanced accumulation of ToLCGanV was detected in the presence of cognate ToLCGanB, however ToLCMumB did not influence the level of ToLCMumV in the agro-inoculated tomato plants. Our results indicate that the cloned viruses form potential virus resistance breaking disease complexes in India. This necessitates to investigate the spread of these disease complexes to major tomato growing regions in the country.

Abstract
Geminiviridae comprises the largest family of plant viruses which causes severe crop losses in India. The highest pungency chilli Bhut-Jolokia or ghost pepper (Capsicum chinense Jaqc.) hails from North-East region of India and is used in many dishes to add flavors and also for its medicinal value. However, this chilli variety is also affected by viruses leading to crop and economic losses. The present study reports the identification of begomoviruses in the infected chilli Bhut-Jolokia leaf samples collected from eight different places of North-East region (Manipur) of India. The infected leaf samples were screened for the presence of viral genome by rolling circle amplification (RCA) followed by PCR using degenerate primer pairs. The subsequent analyses using restriction fragment length polymorphism and sequencing revealed the presence of Cotton leaf curl Multan virus (CLCuMuV), and Tomato leaf curl Patna betasatellite (ToLCPaB). The findings focus on the phylogenetic relatedness, probable recombinational hot-spots and evolutionary divergence of the viral DNA sequences with the current reported begomoviral genome. To the best of our knowledge, this is the first report showing the presence of CLCuMuV, and associated non-cognate ToLCPaB with leaf curl disease of Bhut-Jolokia chillies. The study reveals potential recombination sites on both viral genome and betsatellite which, during the course of evolution, may have aided the virus to progress and successfully establish infection in chilli plants. Taken together, our results suggest a possible spread of CLCuMuV to the hitherto non-host crop in the North-East region of India.

Abstract
Begomoviruses (family Geminiviridae) cause severe diseases in many economically important crops and non-cultivated plants in the warmer regions of the world. Non-cultivated weeds have been reported to act as natural virus reservoirs. In January 2016, Sida plants with yellow mosaic symptoms were found at the edge of an agricultural field in Gujarat, India. Sequence analysis of the viral genomic components cloned from a diseased Sida plant indicated the presence of a distinct monopartite begomovirus (proposed as sida yellow mosaic Gujarat virus) along with a betasatellite (ludwigia leaf distortion betasatellite) and an alphasatellite (malvastrum yellow mosaic alphasatellite). Our results emphasize that this weed may harbor a begomovirus-alphasatellite-betasatellite complex. This host serves as a potential source of virus inoculum, which can be transmitted by whiteflies to other cultivated crops.
