Evaluation of molecular typing methods for some scab-causing Streptomyces strains from Turkey

This study was conducted for identifying phylogenetic relationships between 15 scab-causing Streptomyces species including S. bottropensis, S. europaeiscabiei , S. scabiei , S. stelliscabiei and, other 11 Streptomyces sp. All of the strains were originally isolated from symptomatic potatoes in Erzurum Province, The Eastern Anatolia Region of Turkey. Some morphological and biochemical properties of the strains were defined in our former research. Then, 16 s rRNA regions of them were sequenced. After the sequence data assembly, phylogenetic analyzes were performed. The phylogenetic analyses revealed that the strains are involved in the same major group and, substantially similar to reference strains. Additionally, some subgroup formations were also recorded. Moreover, Repetitive element-based PCR (Rep-PCR), Enterobacterial repetitive intergenic consensus (ERIC-PCR), and BOX-PCR fingerprinting molecular typing methods were used for as molecular typing methods. According to our knowledge, this is the first report on phylogenetic relationships of scab-causing Streptomyces species from Turkey. However, the identification of most pathogenic strains remained at the species level.
