differential impacts of virus diversity on biomass production of a native and an exotic grass host.	pathogens are common and diverse in natural communities and have been implicated in the success of host invasions. yet few studies have experimentally measured how pathogens impact native versus exotic hosts, particularly when individual hosts are simultaneously coinfected by diverse pathogens. to estimate effects of interactions among multiple pathogens within host individuals on both transmission of pathogens and fitness consequences for hosts, we conducted a greenhouse experiment using califo ...	2015	26230720
epidemiology and integrated management of persistently transmitted aphid-borne viruses of legume and cereal crops in west asia and north africa.	cool-season food legumes (faba bean, lentil, chickpea and pea) and cereals (bread and durum wheat and barley) are the most important and widely cultivated crops in west asia and north africa (wana), where they are the main source of carbohydrates and protein for the majority of the population. persistently transmitted aphid-borne viruses pose a significant limitation to legume and cereal production worldwide. surveys conducted in many countries in wana during the last three decades established t ...	2009	19152820
molecular diversity of the coat protein-encoding region of barley yellow dwarf virus-pav and barley yellow dwarf virus-mav from latvia and sweden.	the sequence variability of barley yellow dwarf virus-pav (pav) and barley yellow dwarf virus-mav (mav) was studied by comparing 502 nucleotides from the coat protein-encoding region of six isolates from latvia and four from sweden. the diversity within mav was low (>97% sequence identity), also when compared to isolates from usa and china. in contrast, the variability among pav isolates was greater and phylogenetic analysis including isolates of a wide geographic origin detected two major clust ...	2004	15045570
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
