Tomato yellow leaf curl (TYLC) and tomato leaf curl (ToLC) diseases are serious constraints to tomato production in Mali and other countries in West Africa. In 2003 and 2004, samples of tomato showing virus-like symptoms were collected during a survey of tomato virus diseases in Mali. Three predominant symptom phenotypes were observed: (1) TYLC/ToLC (stunted upright growth and upcurled leaves with interveinal yellowing and vein purpling), (2) yellow leaf crumple and (3) broccoli or bonsai… Expand
A severe symptom phenotype in tomato in Mali is caused by a reassortant between a novel recombinant begomovirus (Tomato yellow leaf curl Mali virus) and a betasatellite.
TLDR
Results indicate that TYLCMLV causes tomato yellow leaf curl disease throughout West Africa, whereas TYLC MLV and CLCuGB represent a reassortant that causes the severe symptom phenotype in tomato. Expand
Molecular characterization of a new begomovirus and divergent alphasatellite from tomato in Cameroon
TLDR
The aim of this research was to determine etiology and to carry out the first molecular characterization of the suspected begomoviral causal agent(s) and associated ssDNA satellites in tomato crops in West Africa. Expand
Two genetically related begomoviruses causing tomato leaf curl disease in Togo and Nigeria differ in virulence and host range but do not require a betasatellite for induction of disease symptoms
TLDR
Replication and systemic spread of ToLCTGB in tomato was mediated by ToLCKuV-TG and ToLCNGV; however, the betasatellite had no effect on disease symptoms induced by either begomovirus and did not appear to play a role in ToLCD. Expand
Complete sequences of tomato leaf curl Palampur virus isolates infecting cucurbits in Iran
TLDR
It is reported here that an ongoing TLCD and TYLCD epidemic in Iran is caused by variants of tomato leaf curl Palampur virus (ToLCPMV), a newly proposed begomovirus species previously only detected in India. Expand
Characterization of a New World Monopartite Begomovirus Causing Leaf Curl Disease of Tomato in Ecuador and Peru Reveals a New Direction in Geminivirus Evolution
TLDR
It is established that ToLDeV is an emergent NW monopartite begomovirus that is causing ToLCD in Ecuador and Peru, and evidence is presented that it emerged from the DNA-A component of a NW bipartite progenitor via convergent evolution and recombination. Expand
Rasta Disease of Tomato in Ghana is Caused by the Pospiviroids Potato spindle tuber viroid and Tomato apical stunt viroid.
TLDR
PSTVd and TASVd isolates from Ghana induced rasta symptoms in the highly susceptible tomato cultivar Early Pak 7 and mild or no symptoms in Glamour, and symptomless infections in a number of other solanaceous species. Expand
Phenotypic and molecular screening of some tomato germplasm for resistance to tomato yellow leaf curl virus disease in Ghana
TLDR
The results suggested that accessions that indicated symptoms of the disease on the field but had no TYLCV DNA amplification could be due to other viruses or virus strain. Expand
The Viral Etiology of Tomato Yellow Leaf Curl Disease - A Review
TLDR
This paper provides an overview of the most outstanding achievements in TYLCV research that may lead to more effective control strategies and describes the recent finding of a suppressor of gene silencing encoded by one of theTYLCV-Isr genes. Expand
Roles and interactions of begomoviruses and satellite DNAs associated with okra leaf curl disease in Mali, West Africa.
TLDR
It is established that OLCD in Mali is caused by a complex of monopartite begomoviruses and a promiscuous betasatellite with an associated parasitic DNA1 satellite. Expand
Variation in the susceptibility of tomato (Lycopersicon solanum L.) genotypes to tomato yellow leaf curl virus (TYLCVD) infections at coastal savannah and forest zones of Ghana
TLDR
The whitefly population was significantly affected by genotype by environment interaction indicating variation of white fly population from location to location. Expand

Tomato yellow leaf curl virus in the Dominican Republic: Characterization of an Infectious Clone, Virus Monitoring in Whiteflies, and Identification of Reservoir Hosts.
TLDR
The complete nucleotide sequence of a full-length infectious clone of an isolate of Tomato yellow leaf curl virus (TYLCV) from the Dominican Republic was determined and established that TYLCV-[DO] is a bonafide TY LCV isolate, and provided further evidence for the introduction of the virus from the eastern Mediterranean. Expand
A worldwide survey of tomato yellow leaf curl viruses
TLDR
Results were supported by DNA and protein sequence comparison, which indicate that tomato geminiviruses fall into three main clusters representing viruses from 1) the Mediterranean/Middle East/African region, 2) India, the Far East and Australia, and 3) the Americas. Expand
Tomato Yellow Leaf Curl Virus
TLDR
Tomato plants with various levels of resistance have been genetically engineered by expressing functional as well as dysfunctional viral genes, and by antisense RNA and post-translational gene-silencing strategies. Expand
Tomato yellow leaf curl virus: a whitefly-transmitted geminivirus with a single genomic component.
TLDR
Effective whitefly-mediated transmission of the virus from agroinoculated plants to test plants demonstrated that the cloned molecule carries all the information needed for virus replication, systemic infection, and transfer by whiteflies. Expand
Solanum nigrum: an indigenous weed reservoir for a tomato yellow leaf curl geminivirus in southern Spain
TLDR
Results indicate the importance of S. nigrum as a weed host/reservoir for a TYLCV and its possible role in the spread of this virus within Europe. Expand
Introduction of Tomato Yellow Leaf Curl Virus in Florida and Implications for the Spread of This and Other Geminiviruses of Tomato.
TLDR
A number of regulatory procedures, as well as field management practices, were implemented in the 1997-98 production season to minimize the movement of TYLCV-Is within and out of the state. Expand
Occurrence of whitefly-transmitted geminiviruses in crops in Burkina Faso, and their serological detection and differentiation
Summary Whitefly-transmitted geminiviruses were found to be associated with four diseases of crop plants in Burkina Faso: cassava mosaic, okra leaf curl, tobacco leaf curl and tomato yellow leafExpand
Nucleotide sequences from tomato leaf curl viruses from different countries: evidence for three geographically separate branches in evolution of the coat protein of whitefly-transmitted geminiviruses.
TLDR
Comparison of the four CP sequences deduced here with those of 18 WTGs previously studied indicated that their relationships can be represented by a tree with three branches that are unrelated to plant host species but which contains viruses from the Americas, Africa to the Middle East, and Asia to Australia, respectively.

A single-stranded DNA molecule approximately 1350 nucleotides in length is identified which, when coinoculated with the begomovirus to cotton, induces symptoms typical of CLCuD, including vein swelling, vein darkening, leaf curling, and enations. Expand
