DNA fingerprinting and genome mapping in meadowfoam

Creator:: Katengam, Sureeporn
Abstract:: Marker information in the new oilseed crop, meadowfoam, is limited. Molecular markers to facilitate meadowfoam breeding and cultivar improvement are not available. The knowledge of genetic relationships among recent germplasm is not known. The objectives of this study were (i) to gain an understanding of genetic diversity and relationship patterns...

Gene flow from transgenic glyphosate-resistant creeping bentgrass (Agrostis stolonifera L.) at the landscape level

Creator:: Zapiola, Maria Luz
Abstract:: Creeping bentgrass (Agrostis stolonifera L.) is an outcrossing, small- seeded, perennial grass that can establish outside of cultivation and has several compatible relatives. Glyphosate is a nonselective, broad spectrum, herbicide. Transgenic glyphosate-resistant (GR) creeping bentgrass (GRCB) was developed by The Scotts Company and Monsanto, but is still under USDA-APHIS regulated...

Small broomrape (Orobanche minor) management using wheat (Triticum aestivum) as a false host

Creator:: Al-thahabi, Salam A.
Abstract:: Small broomrape (Orobanche minor) is an obligate, chlorophyll-lacking parasite that parasitizes red clover (Trifolium pratense) roots. This study was conducted to develop and implement an integrated, biologically based control program for small broomrape by using wheat as a false host to reduce the soil seed bank. The relationship between temperature...

Potential impacts of canola (Brassica napus L.) on vegetable seed production in the Willamette Valley of Oregon

Creator:: Quinn, Michael P.
Abstract:: In the Willamette Valley of Oregon, a combination of the need for rotational crops and an increased desire for biofuel production created interest in planting Brassica napus (canola). However, questions were raised arisen over the potential damage canola production could have on the preexisting Brassica vegetable seed industry. To address...

Vernalization requirements and seed dormancy of jointed goatgrass (Aegilops cylindrica)

Creator:: Fandrich, Lynn
Abstract:: Jointed goatgrass (Aegilops cylindrica Host) infestations in winter wheat (Triticum aestivum L.) production regions of the central and western USA result in severe economic losses in the wheat market. Field and greenhouse studies were conducted to determine the vernalization requirements of winter wheat, spring wheat, jointed goatgrass, and wheat by...

Hybridization between imidazolinone-resistant wheat (Triticum aestivum L.) and jointed goatgrass (Aegilops cylindrical Host.) and selection pressure impacts on proportion of resistance alleles

Creator:: Martins, Bianca Asssis Barbosa
Abstract:: Imazamox-resistant wheat (Clearfield®) cultivars carry the Imi1 gene, which confers resistance to the imidazolinone (IMI) herbicide imazamox. Imazamox provides selective control of jointed goatgrass and other weeds in IMI-resistant wheat. Imi1 gene flow between IMI-resistant wheat and jointed goatgrass may occur via hybridization and backcross events. In 2009 and 2010,...

Microbial and biochemical dynamics of ectomycorrhizal mat and non-mat forest soils

Creator:: Kluber, Laurel A.
Abstract:: Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

The link between nitrogen cycling and soil microbial community composition in forest soils of western Oregon

Creator:: Boyle, Stephanie A.
Abstract:: The objectives of this thesis were to examine the links between soil microbial community composition and function using the nitrogen (N) cycle as a model for these interactions and to assess the impact of environmental factors such as microclimate, vegetation type, and nutrient availability on microbial diversity and N transformations...
