T-budding grafting technique was successful for phytoplasma transmission from infected sesame and basil plants to healthy periwinkle ( <i>Catharanthus roseus </i>) plants in controlled conditions. Phytoplasmas were detected in pepper, tomato, basil, sesame and bindweed and from some insect samples. Total nucleic acid isolation was accomplished by the CTAB method. Direct and Nested PCR were used employing R16F1/R16R0 and R16F2n/R16R2 primer pairs respectively. <br /> </p> <p>Conclusions: DNA of positive samples were sequenced, and uploaded to Genbank, and were identified as Ca. Phytoplasma trifolii on pepper (MT993358), sesame (MT994434), tomato (MT992754), basil (MT994432), <i>Empoasca </i> sp. (MT994430), <i>Exitianus capicola </i> (MT994433), <i>Euscelidius </i> sp. (MT994431); and as Ca. Phytoplasma solani on binweed (MT993422) and tomato (MT992796). <br /> </p> <p>Significance and Impact of the Study: According to our knowledge, this study is the first to identify and upload to Genbank of Ca. Phytoplasma trifolii on basil and <i>Empoasca </i> sp., <i>Exitianus capicola </i> and <i>Euscelidius </i> sp. as insect vectors of the diseases in Turkey. <br /> </p>}, number={2}, publisher={Hatay Mustafa Kemal University}, organization={Hatay Mustafa Kemal Üniversitesi Bilimsel Araştırma Projeleri Komisyonu tarafından desteklenmiştir}
