Phenotypic and Molecular Screening of Tomato Germplasm for Resistance to Tomato Yellow Leaf Curl Virus
Tomato yellow leaf curl virus (TYLCV) is a major tomato virus in tropical and subtropical regions. In this study, 134 accessions of Solanum lycopersicum and six accessions of Solanum peruvianum were assessed for resistance to an Iranian isolate of TYLCV. Plants were inoculated using whiteflies (Bemisia tabaci) and the reaction of plants was evaluated based on either disease symptoms or viral DN...
متن کاملPhylogenetic analysis and genetic variation of Tomato yellow leaf curl virus based on the V1 gene in Iraq
Tomato yellow leaf curl virus (TYLCV) is a supreme pathogen in tropical and subtropical areas. During 2014-2015, a total of 393 tomato samples showing Tomato yellow leaf curl disease (TYLCD) symptoms were collected from six different provinces of Iraq. In serological assays, 55 out of 393 samples (14%) reacted positively with TYLCV-specific antibodies .The presence of TYLCV was verified in 21 (...
متن کاملNatural recombination between Tomato yellow leaf curl virus-is and Tomato leaf curl virus.
The complete genome sequences (2791 and 2793 nt) of isolates of Tomato yellow leaf curl virus-Is (TYLCV-Is) from Spain (SP72/97) and Portugal (Port2/95) were determined. These isolates are closely related to TYLCV-Is isolates reported in Japan (Japan-A and Japan-S) and Israel (Israel/Mild). Comparison of all sequenced isolates of TYLCV-Is showed that part of the genome comprising the intergenic...
متن کاملThe Tomato Yellow Leaf Curl Virus Resistance Genes Ty-1 and Ty-3 Are Allelic and Code for DFDGD-Class RNA–Dependent RNA Polymerases
Tomato Yellow Leaf Curl Virus Disease incited by Tomato yellow leaf curl virus (TYLCV) causes huge losses in tomato production worldwide and is caused by different related begomovirus species. Breeding for TYLCV resistance has been based on the introgression of multiple resistance genes originating from several wild tomato species. In this study we have fine-mapped the widely used Solanum chile...
