“…This study provides evidence for the interaction of begomoviruses with unrelated DNA satellites, which evolved new complexes of these begomoviruses in Asia. This may occur across continents, leading to the development of novel viruses ( Sattar et al, 2019 ).…”

Plant viruses are responsible for the most devastating and commercially significant plant diseases, especially in tropical and subtropical regions. The genus begomovirus is the largest one in the family Geminiviridae, with a single-stranded DNA genome, either monopartite or bipartite. Begomoviruses are transmitted by insect vectors, such as Bemisia tabaci. Begomoviruses are the major causative agents of diseases in agriculture globally. Because of their diversity and mode of evolution, they are thought to be geographic specific. The emerging begomoviruses are of serious concern due to their increasing host range and geographical expansion. Several begomoviruses of Asiatic origin have been reported in Europe, causing massive economic losses; insect-borne transmission of viruses is a critical factor in virus outbreaks in new geographical regions. This review highlights crucial information regarding Asia’s four emerging and highly destructive begomoviruses. We also provided information regarding several less common but still potentially important pathogens of different crops. This information will aid possible direction of future studies in adopting preventive measures to combat these emerging viruses.

“…The infectious clone of DNA-A, upon agroinfiltration in plants, developed mild symptoms. It demonstrated that three begomovirus species alone could infect N. benthamiana and chili, turning mild symptoms ( Qadir et al, 2019 ; Sattar et al, 2019 ). However, co-inoculation with betasatellite, symptoms of severe leaf curling, downward curling and vein yellowing were observed ( Table 8 and Figure 3C ).…”

Chili (Capsicum annuum L.) is an important vegetable and spice crop of tropical and subtropical regions. Chili plants showing upward leaf curling, leaf crinkling, and leaf yellowing symptoms, collected from Sikar district of Rajasthan, India, were found to be associated with begomovirus and satellite molecules. The presence of virus was confirmed by PCR using virus-specific primer. The full-length genomic DNA-A of three begomovirus (MM-1, CS-1 and RV-1) and two satellites (MM-2 and MM-3) were cloned which was identified from single symptomatic chili plant. The genome organization of isolated three viruses is similar to those of other Old World monopartite begomoviruses. The comparison of the sequences and closest phylogenetic relationships for the begomoviruses, betasatellite and alphasatellite DNAs revealed that MM-1 was designated as DNA-A of Chili leaf curl virus (ChiLCV), CS-1 is considered to be a new distinct species of Tomato leaf curl Gujrat virus (ToLCGV) whereas RV-1 as a new strain of Cotton leaf curl Multan virus (CLCuMuV). The DNA-A component of ChiLCV showed 8.6%, ToLCGV of 16.6% and CLCuMuV of 7.7% average evolutionary divergence, concomitantly, the betasatellite and alphasatellite molecule had 9.9% and 5.9% overall sequence divergence, respectively. Interestingly, most of the begomoviruses were found to be intra-species recombinants. The dN/dS ratio and Tajima D value of all viral DNA-A component and their associated betasatellite showed their selective control on evolutionary relationships. The nucleotide substitution rates were determined for the DNA-A genomes of ChiLCV (7.22 × 10 −4 substitutions site −1 year −1), CLCuMuV (1.49 × 10 −4 substitutions site −1 year −1), ToLCGV (7.47 × 10 −4 substitutions site −1 year −1), the genome of associated ChiLCB (4.20 × 10 −4 substitutions site −1 year −1) and CLCuMuA (1.49 × 10 −4 substitutions site −1 year −1). Agro-inoculation studies indicate that the presence of DNA betasatellite induce severe symptoms in N. benthamiana and chili, suggesting prerequisite association for typical disease development.

“…Healthy N. benthamiana inoculated with PV showed severe symptoms with leaf curling and stunted leaves with severity index 4 (Fig. 1A and Table 2), following (Sattar et al 2019). The presence of PV was detected with PCR and later with Southern blot hybridization (Fig.…”

“…Additionally, during such interactions, viruses possibly recombine with each other (Hou et al 1998;Sanz et al 2000;Pita et al 2001;Saunders et al 2001) and exchange their genomic components or satellites molecules (Saunders et al 2002;John et al 2008). Such interactions between geminiviruses and heterologous components have been empirically proved in various studies (Sattar et al 2019;Iqbal et al 2020;Shafiq et al 2021).…”

The studies described here were intended to examine the transreplication and interactions abilities of a widespread ToLCNDV, and an emerging begomovirus PeLCV associated with its cognate betasatellite TbLCuB. PeLCV, a monopartite begomovirus, has been characterized from many important crops, vegetables and weeds along with its associated TbLCuB. The DNA-B of bipartite ToLCNDV genome has been successfully transreplicated by the DNA-A of different bipartite begomoviruses, albeit with low frequency. Whether PeLCV can transreplicate DNA-B of ToLCNDV is unknown. To unravel this notion, both these viruses were inoculated to the model Nicotiana benthamiana plants in all possible combinations and the in planta existence of viral components were verified by PCR and Southern blot hybridization. The results demonstrated that PeLCV transreplicated and maintained ToLCNDV DNA-B. Whereas, ToLCNDV DNA-A could not transreplicate TbLCuB. Analyses of Rep proteins structure of ToLCNDV and PeLCV revealed a structural resemblance, whereas putative iteron-binding sequences of PeLCV were compatible with the Rep-binding iterons of ToLCNDV-B. The results suggested that PeLCV and ToLCNDV DNA-B can interact synergistically and can be disastrous under field conditions. © 2021 Friends Science Publishers
