Incidence of Viruses Infecting Tomato and Their Natural Hosts in the Southeast and Central Regions of Iran

Abstract

A survey was conducted to determine the incidence of Cucumber mosaic virus (CMV), Beet curly top virus (BCTV), Tomato yellow leaf curl virus (TYLCV), Tomato chlorotic spot virus (TcSV), Potato virus Y (PVY), Potato virus S (PVS), Tomato spotted wilt virus (TSWV), Tomato ringspot virus (TRSV), Tomato aspermy virus (TAV), Arabis mosaic virus (ArMV), Tobacco streak virus (TSV), Tomato bushy stunt virus (TBSV), Tobacco mosaic virus (TMV), and Tomato mosaic virus (ToMV) on tomato (Solanum lycopersicum) in the major horticultural crop growing areas in the southeast and central regions of Iran. A total of 1,307 symptomatic leaf samples from fields and 603 samples from greenhouses were collected from January 2003 to July 2005 in five southeastern and central provinces of Iran. Samples of symptomatic plants were analyzed for virus infection by enzyme-linked immunosorbent assay (ELISA) using specific polyclonal antibodies. ArMV and CMV were the most frequently found viruses, accounting for 25.6 and 23.4%, respectively, of the collected samples. BCTV, TSWV, TMV, PVY, ToMV, and TYLCV were detected in 6.1, 5.8, 5.6, 5, 4.8, and 1.6% of the samples, respectively. TBSV, TAV, TSV, PVS, and TRSV were not detected in any of the samples tested. Double and triple infections involving different combination of viruses were found in 13.9 and 1.7% of samples, respectively. This is the first report of PVY and ArMV as viruses naturally infecting tomato in Iran. Infection of tomato plants with PVY and ArMV was confirmed. Six out of 20 plant species belonging to six genera, growing in tomato fields or in the nearby areas, were found infected with TSWV, TMV, PVY, and CMV.

A global invasion by the thrip, Frankliniella occidentalis: Current virus vector status and its management

“…In July 1998, TSWV was identified from Pittosporum tobira shrubs with foliar ring spots, mild mosaic, and tip necrosis symptoms in a nursery in the Sharon Valley of Israel (Gera et al ., ), and later from several vegetables (Gera et al ., ). Similarly, the virus was also detected from potatoes in 1998 in Iran (Pourrahim et al ., ), and subsequently from soybeans, tomatoes, and cucurbits (Golnaraghi et al ., ; Massumi et al ., , ). TSWV has also been isolated from many important vegetable crops in Jordan and Lebanon (Anfoka et al ., ; Abou‐Jawdah et al ., ).…”

First report of Tobacco mild green mosaic virus infecting tomato in Iran

“…Iran is amongst the seven top producers of tomato (Solanum lycopersicum) in the world with an approximate production of 4,826,396 tonnes yearly (Faostat, 2009) (Massumi et al, 2009). However, Tobacco mild green mosaic virus (TMGMV), already reported in pepper in Asia (Choi et al, 2002;Li & Chang, 2005) has not been identified in Iran yet.…”
