Wheat streak mosaic virus (WSMV) is an eriophyid mite-transmitted virus of the genus Tritimovirus, family Potyviridae. Complete deletion of helper component-proteinase (HC-Pro) has no effect on WSMV virulence or disease synergism, suggesting that a different viral protein suppresses RNA silencing. RNA silencing suppression assays using Nicotiana benthamiana 16C plants expressing GFP were conduc...

Knowledge of crop abiotic and biotic stress is important for optimal irrigation management. While spectral reflectance and infrared thermometry provide a means to quantify crop stress remotely, these measurements can be cumbersome. Computer vision offers an inexpensive way to remotely detect crop stress independent of vegetation cover. This paper presents a technique using computer vision to de...

Abstract Wheat streak mosaic virus (WSMV) is a common wheat causing economic losses to production in the Great Plains of North America. Reproducible inoculation WSMV by mechanical methods essential evaluate resistance breeding lines and relies on successful infectivity particles. We used reverse transcription-quantitative PCR (RT-qPCR) for absolute quantification viral genome copy numbers both ...

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 be...

Current gene introgression-based approaches have made only modest progress toward the goal of developing Canadian wheat cultivars with strong resistance to Fusarium head blight (FHB). Re-examining comparisons of gene induction in resistant and susceptible nearisogenic lines of ‘Sumai 3’, a well-established source of FHB resistance, suggested that resistance was conditioned by effective expressi...

Problems associated with annual grain agriculture, such as soil erosion and water and air pollution, indicate that reliance on annual grain production is a fundamental problem of current agricultural practice (23). Annual plant roots are less efficient micromanagers of water, soil, and soil nutrients than their perennial counterparts, resulting in nutrient and pesticide contamination of water s...

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 32C changed the gene expression for resistance ...

The Palouse Prairie of eastern Washington was identified in the 1997 USDA National Resources Inventory as one of the most highly erodible areas in the United States. It is estimated that 10% of the original topsoil in eastern Washington has been lost since cultivation began in the region in the late 1800s (32). Furthermore, runoff from agricultural land reduces water quality in streams and rive...
