wheat cultivar-specific disease synergism and alteration of virus accumulation during co-infection with wheat streak mosaic virus and triticum mosaic virus.triticum mosaic virus (trimv), the type member of the newly proposed poacevirus genus, and wheat streak mosaic virus (wsmv), the type member of tritimovirus genus of the family potyviridae, infect wheat naturally in the great plains and are transmitted by wheat curl mites. in this study, we examined the ability of these viruses to infect selected cereal hosts, and found several differential hosts between trimv and wsmv. additionally, we examined the interaction between wsmv and trimv in three wh ...201020128696
genetic characterization of north american populations of the wheat curl mite and dry bulb mite.the wheat curl mite, aceria tosichella keifer, transmits at least three harmful viruses, wheat streak mosaic virus (wsmv), high plains virus (hpv), and triticum mosaic virus (trimv) to wheat (triticum aestivum l.) throughout the great plains. this virus complex is considered to be the most serious disease of winter wheat in the western great plains. one component of managing this disease has been developing mite resistance in wheat; however, identification of mite biotypes has complicated deploy ...201223156180
in vitro transcripts of wild-type and fluorescent protein-tagged triticum mosaic virus (family potyviridae) are biologically active in wheat.triticum mosaic virus (trimv) (genus poacevirus, family potyviridae) is a recently described eriophyid mite-transmitted wheat virus. in vitro rna transcripts generated from full-length cdna clones of trimv proved infectious on wheat. wheat seedlings inoculated with in vitro transcripts elicited mosaic and mottling symptoms similar to the wild-type virus, and the progeny virus was efficiently transmitted by wheat curl mites, indicating that the cloned virus retained pathogenicity, movement, and w ...201526214124
the effect of temperature, relative humidity, and virus infection status on off-host survival of the wheat curl mite (acari: eriophyidae).the wheat curl mite, aceria tosichella keifer, is an eriophyid pest of wheat, although its primary economic impact on wheat is due to the transmission of wheat streak mosaic (wsmv), wheat mosaic (also known as high plains virus), and triticum mosaic (trimv) viruses. these viruses cause significant annual losses in winter wheat production throughout the western great plains. temperature and humidity are factors that often influence arthropod survival, especially during dispersal from their hosts, ...201526470294
wheat genotypes with combined resistance to wheat curl mite, wheat streak mosaic virus, wheat mosaic virus, and triticum mosaic virus.the wheat curl mite, aceria tosichella keifer, (wcm) is a global pest of bread wheat that reduces yields significantly. in addition, wcm carries wheat streak mosaic virus (wsmv, family potyviridae, genus tritimovirus), the most significant wheat virus in north america; high plains wheat mosaic virus (hpwmov, genus emaravirus, formerly high plains virus); and triticum mosaic virus (trimv, family potyviridae, genus poacevirus). viruses carried by wcm have reduced wheat yields throughout the u.s. g ...201728087646
population dynamics of the wheat curl mite (acari: eriophyidae) during the heading stages of winter wheat.the wheat curl mite (aceria tosichella keifer) is the only known vector of three viruses in wheat-wheat streak mosaic virus, wheat mosaic virus, and triticum mosaic virus. the economic impact of this disease complex is linked to the presence of suitable hosts prior to winter wheat maturing in early summer and the movement of wheat curl mite from wheat to oversummering hosts prior to wheat harvest. previous research has documented the prevalence and density of mite populations on maturing wheat h ...201728334133
multiple categories of resistance to wheat curl mite (acari: eriophyidae) expressed in accessions of aegilops tauschii.the wheat curl mite, aceria tosichella keifer, is an important pest in the western plains of the united states as well as in most major wheat-growing regions of the world. this mite is a vector of the economically important diseases wheat streak mosaic virus (wsmv), triticum mosaic virus (trimv), and high plains virus (hpv). this study looked at seven accessions of aegilops tauschii (coss) schmal to determine if they exhibit antibiosis, tolerance, and/or antixenosis to the wheat curl mite using ...201223356085
