Identification and Partial Characterization of Viral Agent of Lettuce Big Vein in Tehran Province
Background and Aims: The causal agents of viral lettuce big vein disease are two viruse, Lettuce big vein associated virus (Varicosavirus) and Mirafiori lettuce virus (Ophiovirus). These viruses have coat proteins of similar size but have different morphologies and serologically unrelated.The purpose of this study was to distinguish and detect LBVaV and MiLV in lettuce fields in Tehran Province...

متن کاملMutants of downy mildew resistance in Lactuca sativa (lettuce).
As part of our investigation of disease resistance in lettuce, we generated mutants that have lost resistance to Bremia lactucae, the casual fungus of downy mildew. Using a rapid and reliable screen, we identified 16 distinct mutants of Latuca sativa that have lost activity of one of four different downy mildew resistance genes (Dm). In all mutants, only a single Dm specificity was affected. Ge...
متن کاملIntrogression of Crop Alleles into Wild or Weedy Populations
The evolutionary significance of introgression has been discussed for decades. Questions about potential impacts of transgene flow into wild and weedy populations brought renewed attention to the introgression of crop alleles into those populations. In the past two decades, the field has advanced with considerable descriptive, experimental, and theoretical activity on the dynamics of crop gene ...
متن کاملDetection of Varicosavirus and Ophiovirus in Lettuce Associated with Lettuce Big-Vein Symptoms in Brazil
During surveys undertaken from 1998 to 2003 in the major vegetable growing areas of the city of São Paulo green belt, lettuce (Lactuca sativa) and endive (Cichorium endivia) plants were observed, which showed chlorotic thickening of foliar veins, defective growth and, in some cases, failure to form complete heads. Biological and serological [DAS-Enzyme linked immunosorbent assay (Elisa)] tests ...
