Regional whole plant and molecular response of Kochia scoparia to glyphosate
Author(s):Wiersma, Andrew
Date Issued:2012
Format:born digital; masters theses
Globally, glyphosate (Roundup®) resistant weeds pose a serious challenge to modern agricultural practices that utilize glyphosate for weed control, including Roundup Ready® cropping regimes. Locally, glyphosate resistant ...
EPSPS gene duplication in Palmer amaranth: relative fitness, inheritance, and duplication mechanism of the glyphosate resistance trait
Author(s):Giacomini, Darci A.
Date Issued:2015
Format:born digital; doctoral dissertations
Glyphosate resistant (GR) Palmer amaranth (Amaranthus palmeri S. Wats.) is a weedy plant species that has invaded agricultural fields in at least 25 states, raising the cost of weed control to more than 4x the original ...
Decreased dicamba transport due to increased flavonoid biosynthesis: a candidate dicamba resistance mechanism
Author(s):Pettinga, Dean J.
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 ...
Physiological responses of onion germplasms to Iris yellow spot virus and onion thrips (Thrips tabaci)
Author(s):Boateng, Charles Osei
Date Issued:2012
Format:born digital; doctoral dissertations
Onion (Allium cepa L.) is the most economically important monocot outside of the grasses. Onion thrips (Thrips tabaci), a cosmopolitan and polyphagous insect, infests and damages onion crops grown between sea level and ...
Genetics and genomics of herbicide resistant Kochia scoparia L., The
Author(s):Patterson, Eric L.
Date Issued:2018
Format:born digital; doctoral dissertations
Weed genomics resources lag behind other plant biology disciplines despite larger annual crop losses occurring due to weeds than to plant pathogens or invertebrate pests. To date only a handful of weed genomes are assembled, ...
Investigating the impact of soil type, soil moisture, and soil surface residue cover on the efficacy of Diflufenican
Author(s):Effertz, Andrew David
Date Issued:2021
Format:born digital; masters theses
Diflufenican is a pre-emergent and early post-emergent herbicide that inhibits phytoene desaturase, an essential enzyme in the biosynthesis of carotenoids. It has been used effectively in overseas markets such as Europe ...
Investigating fluroxypyr resistance in Bassia scoparia
Author(s):Todd, Olivia
Date Issued:2021
Format:born digital; doctoral dissertations
Synthetic auxin herbicides are designed to mimic indole-3-acetic acid (IAA), an integral plant hormone affecting cell growth, development, and tropism. Recent developments in synthetic auxin herbicide research have produced ...
Protoporphyrinogen oxidase: origins, functions, and importance as an herbicide target site
Author(s):Barker, Abigail
Date Issued:2021
Format:born digital; doctoral dissertations
Protoporphyrinogen IX oxidase (PPO)-inhibiting herbicides are effective tools to control a broad spectrum of weeds, including those that have evolved resistance to glyphosate. Their utility is being threatened by the ...
