Molecular epidemiology of Cucumber mosaic virus and its satellite RNA

Occurrence of Cucumber mosaic virus on Potato and its Transmission to Muskmelon under Potato-Cucurbit Cropping Pattern Followed in Punjab, India

“…Previous studies done by Gracia-Arenal et al, (2000) and Sacristan et al, (2004) revealed that CMV is transmitted in nature by many aphid species in a non-persistent manner. Again CMV is the major virus infecting large number of cucurbits every year grown in Punjab (Kang et al, 2010).…”

Inter- and Intramolecular Recombinations in theCucumber Mosaic VirusGenome Related to Adaptation to Alstroemeria

“…However, a systematic search of available CMV nucleotide sequences did not indicate that potential recombinational events among numerous analyzed CMV strains occur (7). No natural mixed infection and no genetic exchange between CMV subgroup I and II strains were found (17), indicating that most heterologous genetic recombinations seem to be at a competitive disadvantage (18), although a case of natural interspecies recombination between CMV and TAV has been reported (1). More recently, a homologous recombinational event between RNA 1 and RNA 2 or RNA 3 was demonstrated in vivo in subgroup I CMV when transgene sequences were used as donors (8).…”

Diversity of Plant Virus Populations: A Valuable Tool for Epidemiological Studies

“…Analysis of their sequences indicates that both mechanisms contribute significantly to the generation of variability in the evolution and diversification of certain taxonomic groups [11][12][13][14][15][16]. Recombination and reassortment events may involve members of the same plant virus species [17][18][19], members of different species [20][21][22][23][24] or even genus [25]. Genetic exchange by recombination or reassortment may have important epidemiological implications of practical relevance, even more than mutation, as it has been associated to host jumps, host range expansion, changes in virulence, breaking of host resistance and finally, the emergence of new viral plant diseases.…”
