Fig. 1. Polyacrylamide gel showing the RFLP patterns of RNA2 fragment of the Strawberry mottle virus isolates amplified with 2SMoV1108F-2SMoV2386R primers digested with BfaI, FauI, HaeIII, HincI, and TaqI restriction enzymes of strawberry samples collected in 2015 in Bulgaria and Poland. Lanes: L – Thermo Scientific GeneRuler 100 bp Plus DNA Ladder, fragment sizes in base pairs (from top to bottom): 3000, 2000, 1500, 1200, 1000, 900, 800, 700, 600, 500, 400, 300, 200, 100. Samples: 1. Unkn-1108, 2. Granda-1108, 3. Markat-1108, 4. Pink-1108, 5. karkas-1108, 6. Pegat-1108, 7. Granat-1108.
Fig. 2. Phylogenic analysis of the RNA2 fragment sequences of the SMoV isolates detected in Poland and nine representative SMoV strains. The SMoV isolates characterized during this study are indicated in bold. Phylogenetic tree was constructed by the maximum likelihood algorithm (MEGA 5.2) and the Kimura 3-parameter nucleotide substitution model in using 1,000 bootstrap replicates. Only bootstrap values higher than 60 are shown. The bar indicates the genetic distance as Kimura units. RNA2 sequence of Satsuma dwarf virus (GenBank accession number: AB009959) was used as the external group.
Table 1. Diversity of the RFLP profiles after digestion of RNA2 fragment of SMoV isolates by BfaI, FauI, HincI, TaqI, and HaeIII enzymes. Designation by A or B or C letters indicates the presence of different restriction patterns for the specific enzyme
