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...

Tomato yellow leaf curl virus and root-knot nematodes cause diseases in tomato that can lead to heavy production losses. Resistance genes against both pathogens are available and used in breeding. Molecular markers for resistance gene alleles greatly enhance selection of resistant plants in breeding. In order to make marker-assisted selection for the most commonly used resistance genes in tomat...

The spread of Tomato yellow leaf curl virus (TYLCV) was accompanied by the formation of coat protein (CP) aggregates of increasing size in the cytoplasm and nucleus of infected tomato (Solanum lycopersicum) cells. In order to better understand the TYLCV-host interaction, we investigated the properties and the subcellular accumulation pattern of the non-structural viral protein V2. CP and V2 are...

Tomato yellow leaf curl disease (TYLCD) is a severe threat to tomato crops worldwide and is caused by Tomato yellow leaf curl virus (TYLCV) and several other begomoviruses (genus Begomovirus, family Geminiviridae). Host plant resistance is the best TYLCD control method but limited sources of resistance are available. In this study, two Solanum habrochaites TYLCD-resistance sources, EELM-388 and...

ویروس پیچیدگی زرد برگ گوجه فرنگی (tomato yellow leaf curl virus, tylcv)از جمله بیمارگرهای مخرب گوجه فرنگی است و باعث خسارت اقتصادی در سراسر جهان می شود. به دلیل تنوع و گستردگی این بیمارگر در ایران ردیابی ویروس برای کنترل آن ضروری است. از آنجائیکه روش الایزا (elisa) enzyme-linked immunosorbent assay روشی مناسب برای تشخیص ویروسها در سطوح وسیع است آماده سازی آنتی ژن مورد نیاز برای فرآیند تولید آنت...

Seven field populations of Xiphinema americanum sensu lato from California's major agronomic areas were tested for their ability to transmit two nepoviruses, including the prune brownline, peach yellow bud, and grapevine yellow vein strains of tomato ringspot virus and the bud blight strain of tobacco ringspot virus. Two field populations transmitted all isolates, one population transmitted all...

Geminiviruses are characterized by a circular, single-stranded DNA genome and twinned icosahedral particles. Begomoviruses (whitefly-transmitted geminiviruses) are a major constraint to crop production worldwide. In Brazil, tomato-infecting begomoviruses emerged as serious pathogens over the last 10 years, due to the introduction of a new biotype of the insect vector. Tomato yellow spot virus (...

Tomato yellow leaf curl virus (TYLCV) is one of the most well-known tomato-infecting begomoviruses and transmitted by Bemisia tabaci. Seed transmission has previously been reported for some RNA viruses, but TYLCV has not previously been described as a seed-borne virus. In 2013 and 2014, without whitefly-mediated transmission, TYLCV was detected in young tomato plants germinated from fallen frui...

Evidence for the involvement of a Bemisia tabaci GroEL homologue in the transmission of tomato yellow leaf curl geminivirus (TYLCV) is presented. A approximately 63-kDa protein was identified in B. tabaci whole-body extracts using an antiserum raised against aphid Buchnera GroEL. The GroEL homologue was immunolocalized to a coccoid-shaped whitefly endosymbiont. The 30 N-terminal amino acids of ...
