Advances in molecular systematics of clavicipitaceous fungi (Sordariomycetes: Hypocreales)

Creator:: Kepler, Ryan M.
Abstract:: Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The...

Phylogenetic Estimation and Ancestral State Reconstruction of Rubus (Rosaceae) using Target Capture Sequencing

Creator:: Carter, Katherine A.
Abstract:: Hybridization, polyploidy, and apomixis have made phylogenetic estimation in Rubus challenging. I used target capture to sequence approximately 1000 low copy nuclear loci and the chloroplast genome for 94 accessions representing the genus Rubus and distributed worldwide. Species phylogenies were estimated using two coalescent based methods, ASTRAL-II and SVDQuartets, and...

From fossils to phylogenies

Creator:: Goodwin, Baylee N., Besser, August D., and Ramsey, Stephen A.
Abstract:: The research question address in this study is, “To what extent will the use of hands-on activities for introducing concepts in bioinformatics promote student engagement in after-school STEM club settings?” It is hypothesized that high school students' engagement in hands-on bioinformatics activities promotes their awareness of, and interest in, STEM...

Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

Creator:: Kanda, Kojun
Abstract:: In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

Studies on the centromere-specific histone, CenH3, of Neurospora crassa and related ascomycetes

Creator:: Phatale, Pallavi A.
Abstract:: In eukaryotes, the defined loci on each chromosome, the centromeres, accomplish the critical task of correct cell division. In some organisms, centromeres are composed of a euchromatic central core region embedded in a stretch of heterochromatin and the inheritance and maintenance of centromeres are controlled by dynamic epigenetic phenomena. Although...

Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus

Creator:: Syring, John V.
Abstract:: Data from nuclear ribosomal internal transcribed spacer regions (nrITS) and chloroplast DNA (cpDNA) have failed to resolve phylogenetic relationships in Pinus. To provide greater interspecific resolution, five low-copy nuclear genes were developed from mapped conifer anchor loci. Four genes were sequenced from species representing all Pinus subsections. Individual loci do...

Microsatellite marker development and molecular characterization in highbush blueberry (Vaccinium corymbosum L.) and Vaccinium species

Creator:: Boches, Peter
Abstract:: Pre-existing Expressed Sequence Tag (EST) libraries (1,305 sequences) and a newly constructed microsatellite-enriched genomic library (136 clones) from the V. corymbosum cultivar 'Bluecrop' were screened for unique Simple Sequence Repeat (SSR)-containing sequences. Our goal was to develop a set of robust SSR markers for use in managing the National Clonal...

Characterization of the pathogenicity and phylogeny of members of the Rhodococcus genus

Creator:: Creason, Allison L.
Abstract:: Plant pathogenic Rhodococcus species are persistent pathogens able to cause severe growth deformities on a large range of hosts. The most well studied species, R. fascians is predicted by current models to synthesize a mixture of cytokinins that act to directly perturb the hosts' hormone balances, which results in abnormal...

Systematics of Pacific Northwestern species of the genus Gymnomyces inferred from nuclear ribosomal DNA internal transcribed spacer sequences

Creator:: Whitbeck, Kristen L.
Abstract:: Gymnomyces is an ectomycorrhizal basidiomycete genus in the family Russulaceae estimated to contain less than 50 species worldwide, with 23 species known to occur in the Pacific Northwest. Gymnomyces species are common in Pacific Northwest forests that include Pseudotsuga, Abies, Tsuga, and Quercus. They produce sequestrate (truffle-like) sporocarps with ornamented...

Species identification of Klamath Basin suckers (Pisces : Catostomidae) and an assessment of hybridization using anonymous nuclear loci

Creator:: Wagman, David Wolfe
Abstract:: Low copy number anonymous nuclear loci were used to search for species markers in four species of Klamath Basin suckers. We sequenced 28 randomly chosen loci representing 10,421 bp; 21 loci were similar to sequences in GenBank. Eight fixed sequence differences were found among Klamath species. Locus 120 contained rare...
