wheat streak mosaic virus (wsmv) causes extensive economic damage to wheat (triticum aestivum l.) in many regions of the world. the present study was conducted to find out if the variations in biochemical changes in reaction to wsmv infection in f2 generation of either potentially resistant (adl-cross) or susceptible (marvdasht) cultivars are genetically inherited. a factorial experiment was em...
McMechan, A. J., Tatineni, S., French, R., and Hein, G. L. 2014. Differential transmission of Triticum mosaic virus by wheat curl mite populations collected in the Great Plains. Plant Dis. 98:806-810. Wheat is an important food grain worldwide and the primary dryland crop in the western Great Plains. A complex of three wheat curl mite (WCM)-transmitted viruses (Wheat streak mosaic virus, High p...
North American and Eurasian isolates of Wheat streak mosaic virus (WSMV; genus Tritimovirus) and Oat necrotic mottle virus (ONMV; genus Rymovirus) were examined. Nine WSMV isolates differentially infected oat, barley, inbred maize line SDp2 and sorghum line KS56. The WSMV isolates clustered into groups based on phylogenetic analyses of the capsid protein (CP) cistron and flanking regions. WSMV ...
This review examines current knowledge on the prevalence of weeds and feral grass specie as possible reserves plant viruses in agroecosystems Ukraine. Studies concerning mainly virus infection wheat barley distributed agrosystems cereal crops their impact epidemiology have been summarized this paper. In addition, great attention is focused primary sources main causative agents viral diseases, n...
background and aims: to evaluate the effect of temperature on wheat streak mosaic virus (wsmv) resistance phenotype, through total protein, phenol, and peroxidase activity in bread wheat, a factorial experiment was conducted using adl-cross (resistant) and marvdasht (susceptible) cultivars. materials and methods: results showed that incubation at 32c changed the gene expression for resistance ...
Viral determinants and mechanisms involved in extension of host range of monocot-infecting viruses are poorly understood. Viral coat proteins (CP) serve many functions in almost every aspect of the virus life cycle. The role of the C-terminal region of Wheat streak mosaic virus (WSMV) CP in virus biology was examined by mutating six negatively charged aspartic acid residues at positions 216, 28...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Cross-protection and vector transmission bottlenecks have been proposed as mechanisms facilitating genetic isolation of sympatric viral lineages. Molecular markers were used to monitor establishment and resolution of mixed infections with genetically defined strains of wheat streak mosaic virus (WSMV). Two closely related WSMV strains from the U.S. (Type and Sidney 81) exhibited reciprocal cros...
Monopartite members of the family Potyviridae utilize three virus-encoded proteinases to cleave the viral polyprotein into mature proteins. The amino-terminal region of the viral polyprotein is autolytically cleaved by the P1 proteinase. A domain required for P1 proteinase activity of Wheat streak mosaic virus (WSMV) was mapped using a series of templates with nested 3'-truncations or 5'-deleti...
