Molecular and Biological Characterization of a Trackable Illinois Isolate of Barley yellow dwarf virus-PAV

Cloning and Expression of the Coat Protein Gene of Barley Yellow Dwarf Virus-PAV in Escherichia coli

Sequence characterization of Barley yellow dwarf virus – OYV

Barley yellow dwarf (BYD)-associated viruses are economically important in a wide range of cereals and grasses worldwide. These viruses belong to family Luteoviridae and are efficiently transmitted by aphids in a circulative and non-propagative manner. BYD-associated viruses have a genome of single-stranded positive sense RNA (+ssRNA). Even if isolates of BYD-associated viruses from different p...

Dynamics of Molecular Evolution and Phylogeography of Barley yellow dwarf virus-PAV

Barley yellow dwarf virus (BYDV) species PAV occurs frequently in irrigated wheat fields worldwide and can be efficiently transmitted by aphids. Isolates of BYDV-PAV from different countries show great divergence both in genomic sequences and pathogenicity. Despite its economical importance, the genetic structure of natural BYDV-PAV populations, as well as of the mechanisms maintaining its high...

Barley yellow dwarf virus in barley crops in Tunisia: prevalence and molecular characterization

A field survey was conducted in Tunisia in the North-Eastern regions (Bizerte, CapBon and Zaghouan), the North-Western region (Kef) and the Central-Eastern region (Kairouan) during the 2011/2012 growing season, in order to determine the incidence and the geographic distribution of Barley yellow dwarf virus (BYDVs) in barley fields. Tissue blot immunoassays (TBIA) showed that BYDV was most commo...
