Occurrence and molecular characterization of alfalfa mosaic virus in eggplant in Serbia
In the 2018-19 growing season, a total of 51 leaves of eggplant plants grown under field conditions were collected randomly from nine private gardens at four different localities in the Province of Vojvodina. Eggplants with nearly 40% of plants showing bright yellow to white mosaic or mottling of le...

| Sumario: | In the 2018-19 growing season, a total of 51 leaves of eggplant plants grown under field conditions were collected randomly from nine private gardens at four different localities in the Province of Vojvodina. Eggplants with nearly 40% of plants showing bright yellow to white mosaic or mottling of leaves were found throughout the inspected fields (gardens). The collected samples were analyzed for the presence of alfalfa mosaic virus (AMV), cucumber mosaic virus (CMV) and potato virus Y (PVY) using commercial double-antibody sandwich (DAS)-ELISA kits. Serological analysis of eggplant samples revealed the presence of AMV in 80.39% collected samples. None of the analyzed samples was positive for CMV and PVY. The virus was successfully mechanically transmitted to test plants including Nicotiana benthamiana, Chenopodium quinoa, C. amaranticolor, as well as eggplant seedlings, confirming the infectious nature of the disease. The presence of AMV in eggplants was further verified by reverse transcription-polymerase chain reaction (RT-PCR) and sequencing, using the primers CP AMV1 and CP AMV2 that amplify part of the coat protein (CP) gene. The phylogenetic analysis showed that Serbian AMV isolates grouped into a separate well-supported group together with AMV isolates from Italy, Croatia and previously characterized isolates from Serbia. To our knowledge, this is the first report of AMV infection of eggplant in Serbia. |
