Abstract
In this study, Tobacco mild green mosaic virus (TMGMV) infection was investigated in pepper crops from two regions having high economical importance in Turkey. A total of 397 leaf and fruit samples showing mosaic, yellowing, mottling, and pitting symptoms were collected to test by double antibody sandwich ELISA (DAS-ELISA) using polyclonal antiserum. DAS-ELISA results indicated that 97 out of all tested samples (24.4%) were found to be infected with TMGMV. Samples resulting positive for TMGMV infection were used to amplify the virus coat protein (CP) gene sequences with specific primers by RT-PCR for further molecular characterization of the virus isolates. A comparison of the CP sequences of the virus isolates revealed that the identity of nucleotides ranged between 97.2 and 100%, and the amino acid similarity ranged between 96.8 and 100% among themselves. To the best of our knowledge, this is the first report of TMGMV infection in Capsicum annuum in Turkey.
