Advances in Freshwater Cyanobacterial Genomics

Creator:: Brown, Nathaniel M.
Abstract:: Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

Genomic Resource Development for European Hazelnut (Corylus avellana L.)

Creator:: Rowley, Erik R.
Abstract:: European hazelnut (Corylus avellana L.) is an important crop Oregon's Willamette Valley, producing 99% of the hazelnuts grown in North America and brings over US $60 million dollars to the region annually. Hazelnuts are rich in fiber and vitamins, as well in demand by consumers due to their popularity as...

Mapping of quantitative trait loci for malting quality in a winter X spring barley (Hordeum vulgare, L.) cross

Creator:: Oziel, Adeline M.
Abstract:: Making quality and winterhardiness in barley are "ultimate" phenotypes composed of component, quantitatively inherited traits. A 69-point genome map of the seven chromosomes of barley was used, in conjunction with multi-environment phenotypes for grain yield and malting quality, to determine the chromosome locations of quantitative trait loci (QTLs). A combined...

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...

Simple sequence repeat marker development and fingerprinting in Cuphea lanceolata Ait. and C. viscosissima Jacq

Creator:: Karmarkar, Vidyadhar M.
Abstract:: Microsatellites or simple sequence repeats (SSRs) are highthroughput sequence based DNA markers that have been exploited as tools for measuring genetic distance and diversity in evolutionary studies, protection of intellectual property, genetic resource conservation management, cultivar identification and molecular breeding of crop plants. We isolated and sequenced 1095 clones from...

Identification of quantitative trait loci underlying kernel extra-softness and related traits by linkage and association mapping in wheat (Triticum aestivum L.)

Creator:: Wang, Guomei
Abstract:: Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...

Comparative Genomics of Freshwater Bloom-Forming Cyanobacteria and Associated Organisms

Creator:: Driscoll, Connor B.
Abstract:: The advent of improved DNA sequencing technologies has allowed the analysis of various microbial communities. Bloom-forming freshwater cyanobacteria can produce toxins and taste-and-odor compounds that can negatively affect drinking water supplies. Here, I have employed second- and third-generation sequencing technologies to characterize bloom-forming freshwater cyanobacterial genomes and their associated heterotrophic...

Alternative splicing in the obligate biotrophic oomycete pathogen, Pseudoperonospora cubensis

Creator:: Cumbie, Jason S.
Abstract:: Oomycetes are some of the most devastating pathogens, causing upwards of billions of dollars of damage each year to plants. They also diminish ecological diversity and health through the destruction of trees and shrubs. The genome sequence of Pseudoperonospora cubensis, an obligate plant pathogen and causative agent of downy mildew...

The genetics of winterhardiness in barley : perspectives from genome-wide association mapping

Creator:: von Zitzewitz, Jarislav
Abstract:: Fall-planted barley makes the best use of available precipitation in the Pacific Northwest of the United States. This growth habit is also suitable to many other areas of the world. A prerequisite for production in most of these areas is tolerance of low temperature during the vegetative growth stages. Fall-planted...

Development and application of genomic DNA based methods for the identification and characterization of marine bacterioplankton

Creator:: Lanoil, Brian D.
Abstract:: A series of experiments was performed to determine the feasibility of genomic DNA-based methods for ecological and physiological studies of dominant bacteria from complex natural systems. Two approaches, bacterial chromosomal painting (BCP) and environmental genomics (EG), were evaluated for the potential to identify and enumerate specific bacterial groups in situ...
