Bayesian phylogenetic and recombination analyses of plum pox virus provide a refined vision of its evolutionary history.

ABSTRACT:

Background

The discovery of a plum tree isolate of plum pox virus (PPV, Potyvirus plumpoxi), done in Eastern Albania in 2011 in the frame of an EU-funded survey, which represents a divergent strain named PPV-An, proved to be original and informative for the unraveling of PPV evolutionary history.

Methods

Maximum likelihood and Bayesian phylogenetic methods applied on full-length genomes or selected regions analyzed the affinities of the PPV-An with other PPV strains. Potential recombination events were also evaluated. A refined timeline of PPV evolutionary history integrating recombination events, strains migration and ancestral host state is proposed.

Results

Altogether, the analyses confirm previous hypotheses that PPV-An corresponds to an ancestral, non-recombinant
