Repetitive DNA profiles in Bembidion (Coleoptera : Carabidae) show variation in genomic architecture within and between closely related species

Creator:: Barton, Lindsey M.
Abstract:: The ribosomal cistron (rDNA cistron) is a tandemly repeated region in the genome that encodes for the necessary subunits to form ribosomes, complex molecules responsible for the assembly of amino acids into proteins. They are found within all cellular organisms, and evolve at relatively constant rates, making them ideal for...

Experimental Evolution of Roundup Resistance in Outcrossing Populations of Saccharomyces cerevisiae

Creator:: Hanson, Chloe C.
Abstract:: Evolve & Resequence (E&R) experiments subject laboratory populations to environments controlled by investigators, who then document the phenotypic and genomic changes that take place over many generations. These experiments provide powerful tools for testing of a wide variety of evolutionary questions, especially questions about the nature of adaptive traits. While...

Consequences of Cryopreservation in Diverse Strains of Saccharomyces cerevisiae

Creator:: Wing, Kieslana M.
Abstract:: Experimental evolution is a tool that allows us to measure changes in populations over time in controlled, novel environments. Microbial evolution experiments use cryopreservation – storage at -80°C in glycerol media – to archive experimental populations. Research with Escherichia coli suggests that cryopreservation conditions can affect cell viability and that...

Rapid evolution of post-transcriptionally regulated RESTORER OF FERTILITY-LIKE genes in the genus Arabidopsis

Creator:: Jogdeo, Sanjuro
Abstract:: The Pentatricopeptide Repeat (PPR) gene family produces RNA-binding proteins that target organellar transcripts. The PPR family is expanded in land plants, with nearly 450 genes identified in Arabidopsis thaliana. In plants with a Cytoplasmic Male Sterility (CMS) phenotype, members of the PPR family can act as a RESTORER OF FERTILITY...

Metabolic and Immune Responses in Cnidarian-Symbiodiniaceae Symbiosis and Dysbiosis

Creator:: Sawiccy, Valeri
Abstract:: Coral reefs, found in tropical regions, are renowned for their rich biodiversity and their contributions to ecological, cultural, and economic aspects worldwide. The success of coral reefs hinges on the symbiotic partnership between corals and their dinoflagellate algae, from the family Symbiodiniaceae. The algae reside within the coral host’s gastrodermal...

Phylogenomics and Evolution of Ground Beetles, with an Emphasis on the Speciose Tribes Chlaeniini and Bembidiini (Coleoptera: Carabidae)

Creator:: Pflug, James M.
Abstract:: In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...

Genomic Investigations of Diversity within the Milkweed Genus Asclepias, at Multiple Scales

Creator:: Weitemier, Kevin A.
Abstract:: At a time when the biodiversity on Earth is being rapidly lost, new technologies and methods in genomic analysis are fortunately allowing scientists to catalog and explore the diversity that remains more efficiently and precisely. The studies in this dissertation investigate genomic diversity within the milkweed genus, Asclepias, at multiple...

Onset and breakdown of cnidarian-dinoflagellate symbiosis : a survey of the host transcriptomic response and characterization of the sphingosine rheostat during symbiont colonization and hyperthermal stress

Creator:: Kitchen, Sheila Ann
Abstract:: The symbiosis between cnidarians, such as corals and sea anemones, and photosynthetic dinoflagellates belonging to the genus Symbiodinium spp. is one of the most productive in the marine environment. This mutualistic endosymbiosis allow reef-building corals to lay down the foundation of coral reef ecosystems, which supports a highly biodiverse community...

The impact of the number of kinetochore microtubules on the rate of chromosome segregation

Creator:: Duan, Yunhan
Abstract:: Successful cell division requires proper chromosome movement, including accurate congression to the metaphase plate and proper segregation to spindle poles. Errors that occur in either event can cause chromosome aneuploidy in daughter cells, which may lead to cell death, genetic diseases and cancers (Matson and Stukenberg,2012, Compton, 2000). The force...

Plastome phylogenomics in the genus Pinus using massively parallel sequencing technology

Creator:: Parks, Matthew Benjamin
Abstract:: This thesis summarizes work completed over the previous four years primarily focusing on chloroplast phylogenomic inquiry into the genus Pinus and related Pinaceae outgroups using next-generation sequencing on Illumina platforms. During the time of our work, Illumina sequence read lengths have essentially been limited to 25 to 100 base pairs,...
