“…Quality and quantity of the extracts were checked on agarose gels and spectrophotometer (Picodrop, Cambridge, UK), respectively. In addition to the cotton leaf samples, two samples from unrelated plants (without any begomoviral infection, previously verified by RCA-PCR) and one sample with Tomato leaf curl Bangladesh virus (ToLCBV) and Tomato leaf curl Bangladesh betasatellite (ToLCBB) infection 31 , collected from a distant geographical location (Tezpur, Assam, India, 26.63°N, 92.8°E) were also processed concurrently throughout the experiments. These samples served as controls during the entire experimental procedures.…”

Cotton leaf curl disease (CLCuD) outbreaks caused by CLCuD associated begomoviruses (CABs) significantly constrain cotton production in India and Pakistan. In comparison to the CABs circulating in Pakistan, molecular epidemiology, evolution and recombination patterns of CABs circulating in India are less studied. In this work, we characterized CAB complex sequences obtained from the most recent outbreak (Punjab, India, 2015), and rigorously analyzed them with reference to GenBank sequences, submitted from India, Pakistan and other neighbouring countries, using contemporary bioinformatics approaches. In this manuscript, we illustrate the detection of a recombinant, phylogenetically distinct clade of Cotton leaf curl Multan virus (CLCuMuV), suggesting rebound of CLCuMuV in this region. Interestingly, we could not detect Cotton leaf curl Kokhran virus-Burewala strain (CLCuKoV-Bu), which was prevalent in this region, until now. Our study thus indicates substitution of the ‘virulent resistance breaking’ CLCuKoV-Bu by the re-emerging CLCuMuV recombinants. Our findings corroborate with that of a very recent study from Pakistan and we here discuss epidemiological links between the CAB complexes reported in these two studies. Taken together, these observations signify a shifting epidemiology of CABs, and seem to correlate with the recent prediction of the ‘third epidemic’ of CLCuD in the Indian subcontinent.

“…Studies on host range of ToLCuGuV revealed the six known host, i.e., Capsicum, Solanum lycopersicum, Nicotiana tabacum, Nicotiana benthamiana (http://www.genom e.jp/virus hostd b/21929 9), Xanthium, a weed (Mubin et al 2012) and cotton (Zaidi et al 2015). In the same way, association of ToLCuBB has also been reported with chilli leaf curl virus (ChiLCuV) on chilli plants (Khan and Khan 2016) and with tomato leaf curl Bangladesh virus on G. niveum plants (Datta et al 2015).…”

Papaya leaf curl is an economically important disease occurring in papaya growing tropical and subtropical areas. Papaya leaf curl virus, a begomovirus, is the main causative agent for the disease, but many other begomoviruses as well as betasatellites have also been reported on papaya leaf curl disease. Rapidly evolving host range of begomoviruses is a major issue for developing successful resistance strategies against begomoviral infection considering their expanding host range and mixed infection. In our study, we have identified the presence of begomovirus and associated satellite molecule on papaya showing severe leaf curl symptoms in Lucknow, India. Analysis of complete DNA-A component of this isolate (MG757245) revealed the highest similarity (91%) with tomato leaf curl Gujarat virus (ToLCuGuV), while sequence data of betasatellite (MG478451) showed maximum (89%) identity with tomato leaf curl Bangladesh betasatellite (ToLCuBB). This is the first report on identification of ToLCuGuV and ToLCuBB coinfecting papaya plants in Lucknow, Uttar Pradesh (India).
