Assessment of codivergence of Mastreviruses with their plant hosts

BMC Evolutionary Biology, 2008
Background Viruses that have spent most of their evolutionary time associated with a single host lineage should have sequences that reflect codivergence of virus and host.

Localization of Tobacco Yellow Dwarf Virus Replication Using the In Plant Activation (INPACT) Expression Platform

Viruses, 2020
Geminiviruses and their diseases are a considerable economic threat to a vast number of crops worldwide. Investigating how and where these viruses replicate and accumulate in their hosts may lead to novel molecular resistance strategies.

Recombination hotspots and host susceptibility modulate the adaptive value of recombination during maize streak virus evolution

BMC Evolutionary Biology, 2011
Background Maize streak virus -strain A (MSV-A; Genus Mastrevirus, Family Geminiviridae), the maize-adapted strain of MSV that causes maize streak disease throughout sub-Saharan Africa, probably arose between 100 and 200 years ago via homologous ...

Distribution and identification of luteovirids affecting chickpea in Sudan

Phytopathologia Mediterranea, 2021
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).

Genomic Analysis of the Natural Population of Wheat dwarf virus in Wheat from China and Hungary

Journal of Integrative Agriculture, 2012
During the last decade, the leafhopper transmitted Wheat dwarf virus (WDV) has become a serious problem both in northwestern China and Hungary. In order to study the molecular diversity and population structure of WDV in these two countries, 39 Chinese ...

Mapping of QTLs associated with recovery resistance to streak virus disease in maize

Annals of Agricultural Sciences, 2018
Maize streak virus (MSV, genus Mastrevirus, family Geminiviridae), vectored by the leafhoppers (Cicadulina sp.), is the most economically important viral disease of maize endemic to Sub-Saharan Africa and its offshore islands. Yield losses due to MSV are

Viable chimaeric viruses confirm the biological importance of sequence specific maize streak virus movement protein and coat protein interactions

Virology Journal, 2008
Background A variety of interactions between up to three different movement proteins (MPs), the coat protein (CP) and genomic DNA mediate the inter- and intra-cellular movement of geminiviruses in the genus Begomovirus.

Evolutionary time-scale of the begomoviruses: evidence from integrated sequences in the Nicotiana genome. [PDF]

PLoS ONE, 2011
Despite having single stranded DNA genomes that are replicated by host DNA polymerases, viruses in the family Geminiviridae are apparently evolving as rapidly as some RNA viruses. The observed substitution rates of geminiviruses in the genera Begomovirus

Characterization of a Divergent Strain of Miscanthus Streak Virus from Miscanthus sacchariflorus Using High-Throughput Sequencing Data

PhytoFrontiers
A novel and divergent strain of Miscanthus streak virus (MiSV) was isolated from Miscanthus sacchariflorus from South Korea. The complete genome of this MiSV is 2,675 nt, which is predicted to include four open reading frames on the virus and ...

Functional Transcomplementation between Wheat Dwarf Virus Strains in Wheat and Barley

Viruses, 2019
Wheat dwarf virus, transmitted by the leafhopper Psammotettix alienus in a persistent, non-propagative manner, infects numerous species from the Poaceae family. Data associated with wheat dwarf virus (WDV) suggest that some isolates preferentially infect
