Evidence that dicot-infecting mastreviruses arep articularly prone to inter-species recombination and have likely been circulating in Australia for longer than in Africa and the Middle East
Viruses of the genus Mastrevirus (family Geminiviridae) are transmitted by leafhoppers and infect either mono- or dicotyledonous plants. Here we have determined the full length sequences of 49 dicot-infecting mastrevirus ...
Reliable high-throughput Phenotyping Tools to assess Adaptive Traits for Wheat in Drought Environments
This project successfully demonstrated the value of ICARDA’s elite drought nurseries for the CWANA region and highlighted the opportunity to breed for specific adaptations. The great environmental diversity of the CWANA ...
First report of Cotton leafroll dwarf virus affecting chickpea (Cicer arietinum L.) in Uzbekistan
Chickpea (Cicer arietinum L.; family Fabaceae) plants with symptoms typical of virus infection (chlorosis, stunting, necrosis, yellowing, and reddening) were collected during disease surveys in June 2012 (386 samples from ...
Distribution and identification of luteovirids affecting chickpea in Sudan
In Sudan yellowing viruses are key production constraints in pulse crops.
Field surveys were carried out to identify luteovirids affecting chickpea crops in the
major production regions (Gezira Scheme and River Nile State). ...
Molecular diversity of Chickpea chlorotic dwarf virus in Sudan: High rates of intra-species recombination – a driving force in the emergence of new strains
In Sudan Chickpea chlorotic dwarf virus (CpCDV, genus Mastrevirus, family Geminiviridae) is an important pathogen of pulses that are grown both for local consumption, and for export. Although a few studies have characterised ...
Molecular Marker Information in the Analysis of Multi‐Environment Trials Helps Differentiate Superior Genotypes from Promising Parents
The statistical analysis of multi-environment trial data aims to provide reliable and accurate predictions of genotype performance across the target environments and information on specific performance from the interaction ...
Molecular Diagnosis of Viruses Causing Yellowing and Stunting Symptoms Affecting Pulse Crops in Central West Asia and North Africa Countries
Viruses causing yellowing and stunting are the most important virus diseases affecting pulses in many regions of the world, and were considered for many years to be caused mainly by infection with beet western yellows virus ...
First Report of Cucurbit aphid-borne yellows virus Affecting Chickpea (Cicer arietinum L.) in Sudan
A total of 204 chickpea samples with symptoms typical of virus infection including stunting, yellowing, necrosis, reddening, and tip wilting were collected during February 2013 and March 2015 from 14 chickpea fields located ...
Genetic diversity and recombination between turnip yellows virus strains in Australia
Disease outbreaks caused by turnip yellows virus (TuYV), a member of the genus Polerovirus, family Luteoviridae, regularly occur in canola and pulse crops throughout Australia. To understand the genetic diversity of TuYV ...
Comparison of serological and molecular methods for diagnosis of viruses causing yellowing and stunting symptoms for the pulse crops
The diagnosis of plant viruses that belong to the families Solemoviridae and Tombusviridae, which cause yellowing and stunting symptoms, is very complicated due to the serological cross-reactivity among these viruses. The ...
