| Abstract: | Surveys to identify virus diseases affecting garlic ( Allium sativum ), onion ( Allium cepa ) and Persian leek ( Allium ampeloprasum var. persicum ) were conducted from 1999 to 2002. Surveys covered different regions of Iran (Tehran different vegetable markets, farmer fields and cultivation areas], Noushahr, Chalous, Roudbar, Sari, Hamadan, Touyserkan, Ghazvin and Jiroft). A total of 2045 (1285 garlic, 525 onion and 230 leek) samples showing symptoms of virus infection were collected and tested by ELISA; and in some cases tests were also confirmed by immunoelectron microscopy (IEM) for the presence of Allium viruses. ELISA results showed that the following viruses were detected: Onion yellow dwarf virus (OYDV), Leek yellow stripe virus (LYSV) (genus Potyvirus , family Potyviridae ), Garlic common latent virus (GarCLV), Shallot latent virus (SLV) (genus Carlavirus ), Garlic virus D (GarV-D), Garlic virus B (GarV-B) and Garlic virus C type (GarV-C) (genus Allexivirus ). None of the samples reacted with antibodies to Shallot yellow stripe virus (SYSV) genus Potyvirus , family Potyviridae ), Shallot virus X (ShVX) and Garlic virus A (GarV-A, genus Allexivirus ). GarCLV, SLV, GarV-D, GarV-B and GarV-C are reported for the first time from Allium crops in Iran. |
