        Glyphosate-resistant (GR) kochia (kochia scoparia) has become more common throughout the Western Great Plains, and has now been reported to exist as far south as Texas up to Canada. Further evolution of GR kochia threatens ...

      • Wheat stem sawfly oviposition preference and survivorship on winter wheat and downy brome 

        Author(s):Altilmisani, Nuha Mustafa, author; Peairs, Frank, advisor; Ode, Paul, advisor; Bjostad, Louis, committee member; Byrne, Patrick, committee member
        Date Issued:2016
        Format:born digital; doctoral dissertations
        The wheat stem sawfly Cephus cinctus Norton (Hymenoptera: Cephidae) is a major economic pest of wheat in the United States can decrease the yield and grain quality. Wheat stem sawfly infests both cultivated and uncultivated ...

      • Phylogenetic analysis of Xanthomonas translucens & genome-enabled diagnostic tools for pathogens of cereals and non-cereals 

        Author(s):Langlois, Paul, author; Leach, Jan, advisor; Jahn, Courtney, committee member; Steingraeber, David, committee member
        Date Issued:2016
        Format:born digital; masters theses
        Prevalence of Xanthomonas translucens, which causes bacterial leaf streak (BLS) in cereal crops and bacterial wilt in forage and turfgrass species, has increased in many regions in recent years. Because the pathogen is ...

      • Transcriptome and secretome of two pythium species during infection and saprophytic growth 

        Author(s):Ibarra Caballero, Jorge Rafael, author; Tisserat, Ned A., advisor; Leach, Jan, committee member; Hess, Ann, committee member; Jahn, Courtney, committee member
        Date Issued:2016
        Format:born digital; doctoral dissertations
        In the first part of this dissertation, I describe how we obtained and analyzed the full complement of transcripts –the transcriptome- and the set of secreted proteins –the secretome- of Pythium irregulare and Pythium ...

      • Detecting durable resistance to rice bacterial blight 

        Author(s):Delorean, Emily Elizabeth, author; Leach, Jan, advisor; Verdier, Valerie, committee member; Argueso, Cris, committee member; Brick, Mark, committee member
        Date Issued:2016
        Format:born digital; masters theses
        The productivity of rice, a staple crop worldwide, is limited by pathogens such as Xanthomonas oryzae pv oryzae (Xoo). Controlling yield loss to the resulting disease, bacterial blight, is most effective through growing ...

      • Decreased dicamba transport due to increased flavonoid biosynthesis: a candidate dicamba resistance mechanism 

        Author(s):Pettinga, Dean J., author; Gaines, Todd A., advisor; Ward, Sarah, committee member; Sloan, Daniel, committee member
        Date Issued:2016
        Format:born digital; masters theses
        Resistance to dicamba (a synthetic auxin herbicide) has been documented in Kochia scoparia (L.) Schrad. populations since 1994, but the molecular mechanisms of observed resistance cases remain elusive. An RNA-Seq approach ...
