Özet

© 2021, Centenary University. All rights reserved.Tomato (Solanum lycopersicum) is one of the most financially important vegetable crops. It is a species belonging to the Solanaceae family and is cultivated in many countries, including Turkey. The natural presence of ‘Candidatus Phytoplasma solani’ (‘Ca. P. solani’) from the Stolbur group (16SrXII) in tomato plants is extensively characterized based on the 16S rRNA gene worldwide. Tomato plants displaying abnormality and sterility of flower, purpling, and bushy appearance were observed in the Van province, Turkey. DNA extraction from tomato leaves was performed, and the extracted DNA was used to amplify 16S rRNA sequences using universal primer pairs by double PCR assays. After confirming the presence of the probable agent (‘Ca. P. solani’), nested PCR testing was performed using an appropriate primer set amplifying the SecY and Vmp1 genes of the same DNAs. Amplified PCR yields were then cloned into a pGEM T-Easy vector and sequenced by New Generation System (NGS). Sequenced 1438 bp nucleotides for Vmp1 gene (MN104838) and 905 bp nucleotides for SecY gene (MN125054) revealed 97.38% and 100% maximum nucleotide similarity with formerly published Vmp1 and SecY gene sequences of ‘Ca. P. solani’ species belonged to the Stolbur group (16Sr-XII), respectively. According to the phylogenetic tree created using our gene sequences from ‘Ca. P. solani’, Vmp1, and SecY gene sequences showed a highly phylogenetic affinity with the same sequences of the same agent from Serbia and France, respectively. To the best of our knowledge, this study is the first report to reveal the phylogenetic relationships of ‘Ca. P. solani’ in stolbur group (16Sr XII-A) using SecY and Vmp1 genes in the tomato plant in Turkey based on the non-ribosomal genes.
