Open AccessTaking advantage of a pathogen: understanding how a virus alleviates plant stress response
The simplicity of Tomato yellow leaf curl virus (TYLCV) genome, encoding six proteins only, contrasts with the complexity of its impact on tomato plants. In this review, we discuss our understanding of how TYLCV ...

Interactions Between the Whitefly Bemisia tabaci and Begomoviruses: Biological and Genomic Perspectives
Begomoviruses are an emerging group of plant viruses, exclusively transmitted by the whitefly Bemisia tabaci in a persistent-circulative manner. Despite the economic importance of both, very little is known about...

The Involvement of HSP70 and HSP90 inTomato Yellow Leaf Curl Virus Infection in Tomato Plants and Insect Vectors
Cellular chaperones HSP70 and HSP90 are involved in Tomato yellow leaf curl virus (TYLCV) infection. TYLCV is a begomovirus transmitted by the whitefly Bemisia tabaci to tomato and other crops. In infected tomato...

A developmentally regulated lipocalin-like gene is overexpressed in Tomato yellow leaf curl virus-resistant tomato plants upon virus inoculation, and its silencing abolishes resistance
To discover genes involved in tomato resistance to Tomato yellow leaf curl virus (TYLCV), we previously compared cDNA libraries from susceptible (S) and resistant (R) tomato lines. Among the genes preferentially ...

Bemisia tabaci – Tomato Yellow Leaf Curl Virus Interaction Causing Worldwide Epidemics
Tomato yellow leaf curl virus (TYLCV) is a begomovirus that threatens tomato production worldwide. TYLCV is transmitted in a circulative manner by the whitefly Bemisia tabaci. Once ingested, TYLCV wa...

Tomato yellow leaf curl virus infection of a resistant tomato line with a silenced sucrose transporter gene LeHT1 results in inhibition of growth, enhanced virus spread, and necrosis
To identify genes involved in resistance of tomato to Tomato yellow leaf curl virus (TYLCV), cDNA libraries from lines resistant (R) and susceptible (S) to the virus were compared. The hex...

The Whitefly Genome – White Paper: A Proposal to Sequence Multiple Genomes of Bemisia tabaci
The whitefly, Bemisia tabaci (Gennadius 1889), complex (Brown et al. 1995) can cause extensive damage to crop and ornamental plants. Damage can be biotype specific, including induction of physiological disorders ...

Chapter
Mutualistic and Dependent Relationships with Other Organisms
Whiteflies in general – and Bemisia tabaci in particular – are involved in complex interactions with the host plant, various microorganisms and arthropods (herbivores and natural enemies). These relationships are...

Silencing of a single gene in tomato plants resistant to Tomato yellow leaf curl virus renders them susceptible to the virus
A reverse-genetics approach was applied to identify genes involved in Tomato yellow leaf curl virus (TYLCV) resistance, taking advantage of two tomato inbred lines from the same breeding program—one susceptible (...

Open AccessParasitization by the wasp Eretmocerus mundus induces transcription of genes related to immune response and symbiotic bacteria proliferation in the whitefly Bemisia tabaci
The whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), and the viruses it transmits, are a major constraint to growing vegetable crops worldwide. Although the whitefly is often controlled using chemica...

Horizontal transmission of begomoviruses between Bemisia tabaci biotypes
We have previously shown that the monopartite Tomato yellow leaf curl virus (TYLCV), a begomovirus (family Geminiviridae, genus Begomovirus) infecting tomato plants can be transmitted in a gender-dependent manner...

International Networks to deal with Tomato Yellow Leaf Curl Disease: the Middle East Regional Cooperation Program
Management of this disease has mainly involved methods for reducing the vector population; and in many cases, this was primarily by the application of insecticides. Tomatoes with resistance to Tomato yellow leaf ...

Chapter
Biotic and Abiotic Stress Responses in Tomato Breeding Lines Resistant and Susceptible to Tomato Yellow Leaf Curl Virus
In the eyes of a tomato grower, resistance to TYLCV, as opposed to susceptibility, is defined by the absence of, or mild, disease symptoms, and acceptable yield. In resistant cultivars and breeding lines, the ...

Chapter
Interactions of Tomato Yellow Leaf Curl Virus with its Whitefly Vector
Whiteflies cause damages to many economically important agricultural crops because of their feeding habits and their begomovirus transmissions. The whitefly Bemisia tabaci is a genetically diverse group, which in...

Open AccessDerivation of species-specific hybridization-like knowledge out of cross-species hybridization results
One of the approaches for conducting genomics research in organisms without extant microarray platforms is to profile their expression patterns by using Cross-Species Hybridization (CSH). Several different stu...

Open AccessWhitefly (Bemisia tabaci) genome project: analysis of sequenced clones from egg, instar, and adult (viruliferous and non-viruliferous) cDNA libraries
The past three decades have witnessed a dramatic increase in interest in the whitefly Bemisia tabaci, owing to its nature as a taxonomically cryptic species, the damage it causes to a large number of herbaceous p...

The DNA-B of the non-phloem-limited bean dwarf mosaic virus (BDMV) is able to move the phloem-limited Abutilon mosaic virus (AbMV) out of the phloem, but DNA-B of AbMV is unable to confine BDMV to the phloem
Abutilon mosaic virus (AbMV) and bean dwarf mosaic virus (BDMV) are two phylogenetically related bipartite begomoviruses. While AbMV is restricted to phloem, BDMV spreads to non-phloem tissues. Cell-to-cell and ...

Comparison of Resistance to Tomato Leaf Curl Virus (India) and Tomato Yellow Leaf Curl Virus (Israel) among Lycopersicon Wild Species, Breeding Lines and Hybrids
The objective of this study was to screen wild and domesticated tomatoes for resistance to Tomato yellow leaf curl virus, Israel (TYLCV-Is) and Tomato leaf curl virus from Bangalore isolate 4, India (ToLCV-[Ban4]...
