| two distinct mechanisms regulate luteovirus transmission efficiency and specificity at the aphid salivary gland. | barley yellow dwarf luteovirus (bydv) particles are transmitted by aphids in a species-specific manner. transmission to plants requires that the virus particles be transported across the basal lamina and plasmalemma of the accessory salivary gland (asg). to characterize the role of the asg basal lamina in regulating bydv transmission, five aphid species were microinjected with purified new york isolates bydv-pav or -rpv. both viruses associated specifically only with the asg basal lamina. the ab ... | 1997 | 9049397 |
| vector specificity of barley yellow dwarf virus (bydv) transmission: identification of potential cellular receptors binding bydv-mav in the aphid, sitobion avenae. | two proteins (sam35 and sam50) isolated from head tissues of the aphid vector, sitobion avenae, were identified as potential receptors for barley yellow dwarf virus mav isolate (luteoviridae) based on mav virus overlay assays and immunoblots of urea sds 2-d gels. an anti-idiotypic antibody (mav4 anti-id) that mimics an epitope on mav virions and competes with mav in antibody binding assays also bound to sam50 and sam35 and to six additional proteins including a groel homolog. no mav-binding prot ... | 2001 | 11448166 |
| influence of aphid species and barley yellow dwarf virus on soft red winter wheat yield. | yield loss in soft red winter wheat, triticum aestivum l., caused by aphid-transmitted barley yellow dwarf virus (family luteoviridae, genus luteovirus, bydv) was measured over a 2-yr period in central missouri. rhopalosiphum padi (l.) was the most common and economically important species, accounting for > 90% of the total aphids. schizaphis graminum (rondani), rhopalosiphum maidis (fitch), and sitobion avenae (f.) made up the remainder of the aphids. aphid numbers peaked at wheat stem elongati ... | 2005 | 16539127 |
| variation in transmission efficiency among barley yellow dwarf virus-rmv isolates and clones of the normally inefficient aphid vector, rhopalosiphum padi. | the rmv strain of barley yellow dwarf virus (bydv-rmv) is an unassigned member of the luteoviridae that causes barley yellow dwarf in various cereal crops. the virus is most efficiently vectored by the aphid rhopalosiphum maidis, but can also be vectored with varying efficiency by r. padi and schizaphis graminum. field collections of alate aphids migrating into the emerging winter wheat crop in the fall of 1994 in central new york identified a high proportion of r. padi transmitting bydv-rmv. th ... | 2001 | 18944037 |
| transmission, characterization, and serology of a luteovirus associated with yellow leaf syndrome of sugarcane. | abstract a previously uncharacterized luteovirus was associated with one form of yellow leaf syndrome (yls), a widespread disease of sugarcane (saccharum sp.). the virus was named sugarcane yellow leaf luteovirus (scylv), and was identified in major sugarcane-producing areas of the world. typical disease symptoms were reproduced when scylv was transmitted by melanaphis sacchari or rhopalosiphum maidis from infected to healthy sugarcane, suggesting that this virus may be the causal agent of one f ... | 2000 | 18944599 |
| the complete nucleotide sequence of the genome of barley yellow dwarf virus-rmv reveals it to be a new polerovirus distantly related to other yellow dwarf viruses. | the yellow dwarf viruses (ydvs) of the luteoviridae family represent the most widespread group of cereal viruses worldwide. they include the barley yellow dwarf viruses (bydvs) of genus luteovirus, the cereal yellow dwarf viruses (cydvs) and wheat yellow dwarf virus (wydv) of genus polerovirus. all of these viruses are obligately aphid transmitted and phloem-limited. the first described ydvs (initially all called bydv) were classified by their most efficient vector. one of these viruses, bydv-rm ... | 2013 | 23888156 |
