Genetic variability and evolutionary dynamics of Tomato black ring virus population
Plant Pathology 70 (6), 1521-1531
Abstract: Tomato black ring virus (TBRV) is an important pathogen infecting a wide range of plant species worldwide. Phylogenetic studies of TBRV have already been conducted, although limited by the use of short genomic regions or a reduced amount of isolates. In the present study, we carried out an exhaustive phylogenetic and population genetic analysis based on the coat protein gene (CP) sequence of 57 TBRV isolates originating from different host plants and European geographic regions (47 isolates from Poland, 8 from Lithuania, one from the UK, and one from Hungary). Moreover, the selective pressure acting on particular codons and coevolution of amino acid residues in the CP were analysed. The results clearly showed that the TBRV population is being shaped by recombination and both positive and purifying selection. The analyses revealed that the placement of TBRV isolates in the phylogenetic trees was nonrandom, with isolates clustering according to host plant families and geographic origin.
