  • Recurrent speciation of a tomato yellow leaf curl geminiVirus in Portugal by recombination
    Scientific Reports, 2019
    Co-Authors: Elvira Fiallo-olivé, Helena P. Trenado, Diamantina Louro, Jesús Navas-castillo
    Abstract:

    Recurrent evolution can involve interspecific interactions, recognized to play a primary role in the diversification and organization of life. Both in the Plant and animal kingdoms, the recurrent formation of allopolyploid species has been described. In the virosphere, recombination between isolates of different species has been shown to be a source of speciation. In this work, complete genome analysis showed that speciation through recombination of an emergent DNA Plant Virus, tomato yellow leaf curl Malaga Virus (genus BegomoVirus , family Geminiviridae ), has occurred independently in Portugal and Spain, confirming previous observations with tomato yellow leaf curl Axarquia Virus, also originated independently in Spain and Italy. These results will guide future research to discover new cases of recurrent emergence of recombinant Virus species in geographical areas where the putative parents co-exist or can be introduced. This will reveal the role that recurrent speciation through recombination plays in the evolution of the virosphere and will help to understand the consequences of this phenomenon on the diversification of life.

  • Subterranean Clover Stunt Virus Revisited: Detection of Two Missing Genome Components
    Viruses, 2019
    Co-Authors: Dennis Knierim, Quentin Barrière, Mark Schwinghamer, Paul Chu, Ioana Grigoras, Heinrich-josef Vetten, Bruno Gronenborn, Stephan Winter, John Thomas, Tatiana Timtchenko
    Abstract:

    Subterranean clover stunt Virus (SCSV) is a type species of the genus NanoVirus in the family Nanoviridae. It was the first single-stranded DNA Plant Virus with a multipartite genome, of which genomic DNA sequences had been determined. All nanoViruses have eight genome components except SCSV, for which homologs of two genome components present in all other nanoVirus genomes, DNA-U2 and DNA-U4, were lacking. We analysed archived and more recent samples from SCSV-infected legume Plants to verify its genome composition and found the missing genome components. These results indicated that SCSV also has eight genome components and is a typical member of the genus NanoVirus.
