| Background Potato production is affected by various abiotic and biotic factors such as viruses, fungi, and bacteria. Viruses are considered the main limiting factor in potato production areas.Methods and Results Leaf samples were collected from potato plants showing signs of viral diseases in ve districts of Tokat province in Turkey. To detect the presence of potato viruses, 418 leaf samples were subjected to an RT-PCR test using virusspeci c primers. One or more viruses were detected in 220 (52.63%) leaf samples tested. PVY was the most prevalent (47.12%), followed by PVS (16.74%), PVX (5.98%), and PLRV (5.26%). The PVX and PLRV infections were found to be few. The most common multiple infections were PVY+ PVS with 6.9% rates. Phylogenetic analysis based on sequence analysis of some positive isolates revealed that all Turkish PVS isolates were grouped with the PVSO cluster. Two PVY isolates were clustered with Group PVYN-WI, and one isolates clustered with PVYNNTN isolates in the phylogenetic tree. Regarding nucleotide sequence similarity of the CP region, PVX isolates were divided into two major groups (Group I and Group II). Turkish PVX isolates were grouped within Group I that including isolates referred to as type X. According to phylogenetic analysis of PLRV isolates, Turkish isolates were clustered into two major groups. Six PLRV isolates belong to Group 1 and one isolate was clustered Group 2. |
