| occurrence and distribution of lettuce mosaic disease in tehran province from iran. | lettuce mosaic virus (lmv) cucumber mosaic virus (cmv) and tomato spotted wilt virus (tswv) were identified in fields of tehran province. in this study 452 leaf samples were collected from the fields throughout the tehran province during 2002 and 2003. distribution of lettuce mosaic virus (lmv), cucumber mosaic virus (cmv), tomato spotted wilt virus (tswv)and arabis mosaic virus (armv) was determined with das-elisa. percentage of single infection to lmv. cmv or tswv was 20.58, 15.93 and 9.96% re ... | 2004 | 15756832 |
| biological and molecular characterization of lettuce mosaic virus from tehran province in iran. | in this study, lettuce samples having lmv infection symptoms were collected from tehran fields during 2003. samples tested for lmv infection by immuno printing. three positive samples in immuno printing collected and their characteristics were determined. in mechanical inoculation, these isolates produced symptoms on chenopodium quinoa, c. amaranticolor, gomphrena globosa, nicotiana benthamiana, lactuca sativa cv. mantilia and cv. terocadero (which contains the mol1 resistance gene and susceptib ... | 2004 | 15756833 |
| comparison of biological and molecular characterization of iranian lettuce mosaic virus isolates. | lettuce mosaic virus (lmv) is one of the most damaging viruses in lettuce and endive cultivating regions. in order to review the characteristics of different lmv isolates of iran during 2004-2005 samples were collected from lettuce fields in esfahan, ghom, khorasan, khuzestan and tehran provinces. all of the isolates were detected by lmv polyclonal antiserum (as-0155, dsmz germany) in elisa and tipa tests. biological purification was done for the lmv isolates and then they were maintained and pr ... | 2006 | 17390892 |
