Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...

Identifying the Parameters for Wheat Pollen Electroporation Transformation

Creator:: Liu, Jiang
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world. It has been and continues to be one of the main sources of food for humans and animals. Although traditional wheat breeding has contributed greatly to the improvement of wheat both in productivity and biotic/abiotic stress...

Soil community dynamics in sagebrush and cheatgrass-invaded ecosystems of the northern Great Basin

Creator:: DeCrappeo, Nicole M.
Abstract:: Sagebrush steppe ecosystems in the Great Basin have become increasingly threatened by the proliferation of cheatgrass (Bromus tectorum L.), an invasive annual grass. Diverse sagebrush and perennial bunchgrass landscapes can be converted to homogenous cheatgrass grasslands mainly through the effects of fire. Although the consequences of this conversion are well...

Altered precipitation regime affects the function and composition of soil microbial communities on multiple time scales

Creator:: Zeglin, L. H., Bottomley, Peter J., Jumpponen, A., Rice, C. W., Arango, M., Lindsley, A., McGowan, A., Mfombep, P., and Myrold, D. D.
Abstract:: Climate change models predict that future precipitation patterns will entail lower-frequency but larger rainfall events, increasing the duration of dry soil conditions. Resulting shifts in microbial C cycling activity could affect soil C storage. Further, microbial response to rainfall events may be constrained by the physiological or nutrient limitation stress...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...

Investigation of hop downy mildew through association mapping and observations of the oospore

Creator:: Parker, Thomas B.
Abstract:: Hop downy mildew is a devastating disease affecting hop requiring expensive fungicide applications throughout the growing season. Plant resistance is highly desirable and theorized as being decidedly quantitative with dominance and epistasis involved in resistance. An association mapping approach using a mixed-model was used to identify AFLP markers associated with...

Evaluating Field Production Issues by Investigating Grain Dormancy and Plant Segregation Patterns in Soft White Winter Wheat

Creator:: McCarthy, Christy A.
Abstract:: Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:: Bedoshvili, David
Abstract:: Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...
