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...

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...

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...

Molecular and genetic analyses of genome variability in Ustilago hordei

Creator:: Agnan, Jacqueline
Abstract:: Pulsed-field gel electrophoresis (PFGE) of the strains representing the 14 races of U. hordei, the causal agent of covered smut on barley, revealed extensive polymorphism in chromosome length and number. The purpose of this study was to determine by two approaches the exact chromosome number for each U. hordei race,...

Repeated sequences associated with inversions and length mutations in the chloroplast genomes of Pseudotsuga and Pinus

Creator:: Hipkins, Valerie D.
Abstract:: To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...

Evidence that the Potyvirus P1 Proteinase Functions in trans as an Accessory Factor for Genome Amplification

Creator:: Verchot, Jeanmarie and Carrington, James C.
Abstract:: The tobacco etch potyvirus (TEV) polyprotein is proteolytically processed by three viral proteinases (NIa, HC-Pro, and P1). While the NIa and HC-Pro proteinases each provide multiple functions essential for viral infectivity, the role of the P1 proteinase beyond its autoproteolytic activity is understood poorly. To determine if P1 is necessary...

Walking tree heuristics for biological string alignment, gene location, and phylogenies

Creator:: Oregon State University. Dept. of Computer Science, Cull, Paul, 1943-, Holloway, James Lee, and Cavener, Jeffrey Douglas
Abstract:: Basic biological information is stored in strings of nucleic acids (DNA, RNA) or amino acids (proteins). Teasing out the meaning of these strings is a central problem of modern biology. Matching and aligning strings brings out their shared characteristics. Although string matching is well-understood in the edit-distance model, biological strings...

Marker development, genome mapping, and cloning of candidate disease resistance genes in sunflower, Helianthus annuus L

Creator:: Gedil, Melaku Ayele
Abstract:: The level of polymorphisms of many biochemical and DNA markers are low in cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA markers is limited. Molecular markers have not been developed for the most important diseases of sunflower, such as downy mildew. The objectives of this study were...

Fine structure of the virus genome in a marine filamentous brown algae, Feldmannia

Creator:: Lee, Amy M.
Abstract:: Viruses or viruslike particles of eukaryotic algae are ubiquitous in aquatic habitats, however, suprisingly little is known about them. The research presented here focused on one such virus which infects a multicellular filamentous brown alga of the genus Feldmannia. Although preliminary studies had been performed on the genome structure of...

A comparison of simulated annealing and genetic algorithms for the genome mapping problems

Creator:: Gunnels, John A.
Abstract:: The data used for the construction of genome maps is imperfect, therefore the mapping of a physically linear structure must take place in a very uneven feature space. As the number of genes to be ordered grows, it appears to be impractical to use exhaustive search techniques to find the...
