Wheat Streak Mosaic Virus Coat Protein Is A Host-Specific Long-Distance Transport Determinant In Oat, Satyanarayana Tatineni
Wheat Streak Mosaic Virus Coat Protein Is A Host-Specific Long-Distance Transport Determinant In Oat, Satyanarayana Tatineni
Department of Plant Pathology: Faculty Publications
Viral determinants involved in systemic infection of hosts by monocot-infecting plant viruses are poorly understood. Wheat streak mosaic virus (WSMV, genus Tritimovirus, family Potyviridae) exclusively infects monocotyledonous crops such as wheat, oat, barley, maize, triticale, and rye. Previously, we reported that WSMV CP amino acids 36–84 are expendable for systemic infection of wheat, maize, barley and rye. In this study, the role of coat protein (CP) in systemic infection of oat by WSMV was examined by using a series of viable deletion mutants. WSMV bearing deletions within or encompassing all of amino acids 36–57 efficiently infected oat, indicating that …

Wheat Production, Gretchen Sassenrath, D. E. Shoup, R. Lollato
Kansas Agricultural Experiment Station Research Reports
Wheat production in southeast Kansas is often limited due to high rainfall during the harvest. In some years, this high rainfall can exacerbate disease pressure, especially fungal infections. This study presents results from a test of fungicide applications to control Fusarium head blight (FHB) or scab in poor quality wheat.
Wheat Variety Response To Seed Cleaning Method And Pesticide Seed Treatment Following A Growing Season With Severe Infestation Of Fusarium Head Blight, R. Lollato, R. Maeoka, B. R. Jaenisch, A. De Oliveira Silva
Wheat Variety Response To Seed Cleaning Method And Pesticide Seed Treatment Following A Growing Season With Severe Infestation Of Fusarium Head Blight, R. Lollato, R. Maeoka, B. R. Jaenisch, A. De Oliveira Silva
Kansas Agricultural Experiment Station Research Reports
Fusarium head blight (scab) is a common concern in eastern and central Kansas. Wheat seed quality might be compromised following a growing season with severe infestation of scab. Our objectives were to evaluate the effects of variety, seed cleaning method, and seed treatment, on wheat stand establishment and yield following a growing season where scab was severe. A trial was established during the 2015-16 growing season using seed harvested from the 2014-15 growing season, which was characterized by severe infestation of scab. Three commonly grown wheat varieties with differing levels of scab resistance (Everest, SY Wolf, and WB Grainfield) were …
Characterization Of Pyrenophora Tritici-Repentis In Wheat And Rye To Study Tan Spot Susceptibility And Insights Into Its Relationship With Stem Rust Resistance, Sidrat Abdullah
Electronic Theses and Dissertations
Tan spot, caused by the ascomycete fungus, Pyrenophora tritici-repentis (Ptr), is a major foliar fungal disease of wheat worldwide. To date, Ptr isolates have been grouped into eight races based on the production of three host selective effectors (toxins), Ptr ToxA, ToxB, and ToxC, which are associated with necrosis and chlorosis symptoms on wheat differential lines. In order to see the correlation between stem rust resistance and tan spot susceptibility in 1970’s, to know the pathogen virulence profile, and explore the sources of tan spot resistance, we recovered isolates from wheat and rye and evaluated wheat and rye lines with …
Value Of Fungicide Application In Wheat Production In Southwest Kansas, A. J. Foster, R. Lollato, M. Vandeveer, E. D. De Wolf
Value Of Fungicide Application In Wheat Production In Southwest Kansas, A. J. Foster, R. Lollato, M. Vandeveer, E. D. De Wolf
Kansas Agricultural Experiment Station Research Reports
During the past several years, applying fungicide to wheat has become a more common practice. The availability of cost-effective generic fungicides, as well as the positive yield responses often reported, seem to be the potential drivers for the adoption of such practices by producers. We conducted a wheat fungicide trial in Garden City, KS, to answer the following questions: 1) Do fungicide applications pay? And 2) Can remote sensing technology be used to quantify the efficacy of different fungicide products? The study consisted of two wheat varieties sown on September 29, 2015 (Oakley CL, highly resistant to stripe rust; and …
