“…Two distinct observations were made while comparing the prevalence of resistance-breaking strains in India when compared to their place of origin (Pakistan). Different CBVs are seen to be associated with a single recombinant betasatellite, CLCuMB, whereas Amrao et al [4,5] report the predominant association of the CLCuMB with only one CLCuBuV. In addition, three conserved mutations were also observed in the C2 gene (1S, 2S and FS) by Amrao et al [4].…”

“…CLCuD in Pakistan is also caused by an array of begomoviruses including cotton leaf curl Alabad virus (CLCuAV), CLCuKoV, CLCuMuV, CLCuBuV, ToL-CNDV and papaya leaf curl virus (PaLCuV) [34]. Recently, during a survey of symptomatic cotton in Sindh (southern Pakistan), cotton leaf curl Gezira virus (CLCuGV), the begomovirus associated with CLCuD in Africa, and a member of a new tentative begomovirus species referred to as Cotton leaf curl Shahdadpur virus (CLCuShV) were identified [5,58].…”

Dominance of resistance-breaking cotton leaf curl Burewala virus (CLCuBuV) in northwestern India

Cotton leaf curl disease (CLCuD) is a major limitation to cotton production on the Indian subcontinent. A survey for viruses causing CLCuD was conducted during the 2009 and 2010 cropping seasons in the northwestern Indian cotton-growing belt in the states of Punjab, Haryana and Rajasthan. Partial sequences of 258 and full-length sequences of 22 virus genomes were determined. This study shows that the resistance-breaking cotton leaf curl Burewala virus (CLCuBuV) is now the dominant virus in many fields. The spread and establishment of the mutant CLCuBuV in northwestern India, the variation in its genomic sequence, its virulence and infectivity, and the implications for cotton breeding are discussed.

“…Recombination is a significant driving force in the evolution of many begomoviruses (Padidam et al 1999). CLCuD-begomoviruses have been shown to have recombinant origin (Amrao et al 2010b;Kumar et al 2010;Sattar et al 2013). Evolution of recombinant betasatellite and their association with resistance breaking of CLCuD in cotton have also been reported (Amin et al 2006;Mansoor et al 2006;Amrao et al 2010b).…”

Cotton leaf curl disease (CLCuD), caused by monopartite begomoviruses and its satellite molecules, is one of the serious constrains in cultivation of cotton in India. In the present study, five CLCuD-begomovirus and its associated satellite molecules were characterized based on rolling circle amplification and sequencing of complete genome. Sequence analysis showed 82-99 % nucleotide identity among them. The phylogenetic analysis and nt identity matrix determined that of the five CLCuD-begomovirus isolates, three IARI-34, IARI-42 and IARI-50 were members of Cotton leaf curl Multan virus (CLCuMuV)-Rajasthan isolates, designated as CLCuMuV-Rajasthan-34 and two, IARI-30 and IARI-45 of Cotton leaf curl Kokhran virus (CLCuKoV)-Burewala isolates, designated as CLCuKoV-Burewala-45. The present CLCuMuVRajasthan-34 is recombinant isolate showing recombination events in IR, C1 and C4 regions of its genome with high probality (P = 9.9 9 10 -10 -3.2 9 10 -6 ). Same species of betasatellite (1371 nt) molecules obtained from both the present isolates was related with cotton leaf curl Multan betasatellite by 89-97 % nt identity. Three alphasatellites (1366-1396 nt) related to Cotton leaf curl Burewala alphasatellite and Gossypium darwinii symptomless alphasatellite by 86 % nt identity were also obtained. This is the first report of appearance of CLCuKoV-Burewala isolate and CLCuD associated alphasatellites in New Delhi. The present study demonstrated that CLCuD in New Delhi is caused by three kinds of variants, two are strains of CLCuMuV and one of CLCuKoV, either by single or mixed infection along with beta-and alphasatellite molecues.

“…CLCuV is most closely related to 'Old World' viruses such as Indian cassava mosaic and tomato yellow leaf curl. Seven diverse species of begomoviruses have been found which is associated with the CLCuD in the Indian subcontinent specifically Cotton leaf curl Multan virus (CLCuMV), Cotton leaf curl Rajasthan virus (CLCuRV), Cotton leaf curl Alabad virus (CLCuAV), Cotton leaf curl Kokhran virus (CLCuKV) and Papaya leaf curl virus (PaLCuV), Cotton leaf curl Bangalore virus (CLCuBV) associated with alphasatellite and betasatellite molecules (Mansoor et al, 2003b;Briddon 2003) and Cotton leaf curl Burewala virus (CLCuBuV) (Amrao et al, 2010).…”
