“…Such promiscuity will undoubtedly facilitate diversification and dissemination of satellites. For example, a single DNA-b is known to be associated with several distinct cotton begomoviruses and a resistance breaking strain of the disease emerging in Pakistan is associated with a recombinant DNA-b (Amin et al, 2006). Also, Sri Lankan cassava mosaic virus, a bipartite begomovirus, has been shown to function as a monopartite begomovirus and alter its host range in the presence of AYVV DNA-b (Saunders et al, 2002).…”

Pseudorecombination studies in Nicotiana benthamiana demonstrate that Ageratum yellow vein virus (AYVV) and Eupatorium yellow vein virus (EpYVV) can functionally interact with DNA-β satellites associated with AYVV, EpYVV, cotton leaf curl Multan virus (CLCuMV) and honeysuckle yellow vein virus (HYVV). In contrast, CLCuMV shows some specificity in its ability to interact with distinct satellites and HYVV is able to interact only with its own satellite. Using an N. benthamiana leaf disk assay, we have demonstrated that HYVV is unable to trans-replicate other satellites. To investigate the basis of trans-replication compatibility, deletion mutagenesis of AYVV DNA-β has been used to localize the origin of replication to approximately 360 nt, encompassing the ubiquitous nonanucleotide/stem–loop structure, satellite conserved region (SCR) and part of the intergenic region immediately upstream of the SCR. Additional deletions within this intergenic region have identified a region that is essential for replication. The capacity for DNA-β satellites to functionally interact with distinct geminivirus species and its implications for disease diversification are discussed.

“…The emergence of new recombinant begomoviruses has recently been found to be associated with the destructive diseases of most economically important crops around the globe (Padidam et al, 1999;Amin et al, 2006). This group of viruses has a high ability for genomic variation independently from their host; however, at the same time, they reveal great geographical dependence.…”

Leaf yellowing and rolling with slight crinkling was observed in radish plants in Oman, indicative of a begomovirus infection. Viral sequences from radish were 99% identical to sequences of Tomato yellow leaf curl virus (TYLCV) and Chilli leaf curl virus (ChiLCV), from Oman. No beta-or alpha-satellites were detected. Infectious clones were developed and infectivity analyses of isolated viruses were done in a model host Nicotiana benthamiana. Both viruses, when inoculated separately, produced typical symptoms; however, symptom severity increased when these viruses were co-inoculated. Southern analyses confirmed that virus accumulation was high when both viruses were inoculated as compared to independent inoculation. Realtime qPCR analyses showed that copy number of both viruses was 1 X 10 6 copies when N. benthamiana plants were inoculated with either TYLCV or ChiLCV; however, the copy number increased to 1 X 10 8 copies when the two viruses were co-inoculated together in N. benthamiana.

“…A newly emerged strain was reported to be cotton leaf curl Burewala virus (CLCuBuV), which was a recombinant of cotton leaf curl Multan virus and cotton leaf curl Kokhran virus. The betasatellite associated with CLCuBuV was also a new strain "Burewala strain", which was a recombinant of CLCuMuB and tomato leaf curl betasatellite (Amin et al, 2006).…”

ABSTRACT. In Pakistan, cotton crop has been under enormous threat of cotton leaf curl disease (CLCuD) over the last four decades. In order to estimate genetic diversity in cotton germplasm CLCuD resistance, we assessed 100 cotton genotypes for their CLCuD resistance/tolerance and other related agronomical traits. Various statistical analytical tools, including correlation analysis, cluster analysis, and principal component analysis (PCA), were used to select the best genotypes. These genotypes can be used in future breeding programs to generate CLCuD resistant varieties. The same set of procedures could be utilized for other diseases in other crops. CLCuD incidence showed a significant negative genotypic correlation with yield-contributing traits followed by a significant negative association for phenotypic correlation. The seed cotton yield showed significant positive genotypic and phenotypic correlations with plant height, number of bolls per plant, and boll 2 M. Javed et al. Genetics and Molecular Research 16 (1): gmr16019446 weight. From the PCA we identified five principal components (PCs) that explained a significant amount of the variance among the variables, which may be used for selection of cotton genotypes with CLCuD resistance. Of the five PCs, the first four contributed more towards the total variability and had eigenvalues greater than one. The cluster analysis showed that the genotypes in one of the clusters performed particularly well with respect to CLCuD tolerance. These genotypes can be utilized for development of varieties with increased CLCuD tolerance.
