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 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 کاملDevelopment of a Scale for Evaluation of Tomato yellow leaf curl virus Resistance Level in Tomato Plants.
ABSTRACT We have developed a scale of differential hosts that enables the determination and comparison of level of resistance to Tomato yellow leaf curl virus (TYLCV) expressed by resistant tomato lines or by individual plants in a segregating population. The scale is composed of seven different homozygous tomato genotypes that exhibit different levels of TYLCV resistance, ranging from fully su...

متن کاملPyramiding of genes conferring resistance to Tomato yellow leaf curl virus from different wild tomato species
Tomato (Solanum lycopersicum) production in tropical and subtropical regions of the world is limited by the endemic presence of Tomato yellow leaf curl virus (TYLCV). Breeding programmes aimed at producing TYLCV-resistant tomato cultivars have utilized resistance sources derived from wild tomato species. So far, all reported breeding programmes have introgressed TYLCV resistance from a single w...
