In this study, it was attempted to determine the resistance of different tomato lines spotted wilt virus (TSWV), yellow leaf curl (TYLCV), and root-origin nematodes (Meloidogyne spp.) using molecular DNA markers. For purpose, out 96 be tested, Sw5-2 for ripening Ty3P6-25 (TYLCV) marker Mi23, which determines root-knot spp.), were used by PCR. Ty3P6-25, that TYLCV, found susceptible (rr) in 34 l...

Tomato yellow leaf curl virus (TYLCV), a member of the genus Begomovirus, is responsible for one of the most devastating viral diseases in tomato-growing countries and is becoming a serious problem in many subtropical and tropical countries. The climate in Korea is getting warmer and developing subtropical features in response to global warming. These changes are being accompanied by TYLCV, whi...

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...

Tomato production in the Mediterranean region and elsewhere is under constant threat of the whitefly-transmitted begomoviruses that cause Tomato yellow leaf curl disease (TYLCD). Sequencing has indicated that the generic ‘TYLCV’ includes a large number of viruses and strains. We studied the distribution of the tomato yellow leaf curl disease-associated viruses in Egypt, Israel, Jordan and Leban...

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 (...

In this study, we investigated the tritrophic interactions among a persistently transmitted plant virus, Tomato yellow leaf curl virus (TYLCV), its insect vector, the sweetpotato whitefly Bemisia tabaci, and a parasitoid, Encarsia formosa Gahan, one of the most extensively used biological control agents. As an emerging invasive pest worldwide, the two most damaging whiteflies are B. tabaci B an...

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...

For many insect-vectored plant viruses, the relationship between feeding behavior and vector competence may prove integral to an understanding of the epidemiology of the resulting plant disease. While plant-infecting viruses are well known to change host plant physiology in a way that makes them more attractive to vectors, viral manipulation of the vectors themselves has only recently been repo...

Glick E., Levy Y., Gafni Y. (2009): The viral etiology of tomato yellow leaf curl disease – a review. Plant Protect. Sci., 45: 81–97. Tomato yellow leaf curl disease (TYLCD) is one of the most devastating plant diseases in the world. As a result of its continuing rapid spread, it now afflicts more than 30 tomato growing countries in the Mediterranean basin, southern Asia, Africa, and South, Cen...
