title: Genetic diversity, distant phylogenetic relationships and the occurrence of recombination events among cucumber mosaic virus isolates from zucchini in Poland.
abstract: In recent years, the occurrence of cucumber mosaic virus (CMV) has been noted in zucchini crops in Poland. Beside characteristic isolates, which displayed mosaics and chlorosis on infected plants, new necrotic isolates have also been identified. Here, we analysed the molecular variability of 27 isolates of CMV collected from zucchini in various regions of the country. Sequence and phylogenetic analysis based on the genes encoding the coat (CP) and movement (MP) proteins revealed that the Polish isolates belong to two subgroups: IA and II, with the prevalence of subgroup II. New recombinant variants with an IA-MP/II-CP pattern for RNA3 were also detected.
