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...

Identification and Functional Characterization of Genes that Regulate Biomass Production, Floral Development, and Leaf Senescence in Populus Species using Genetic Engineering and Bioinformatics Tools

Creator:: Lu, Haiwei
Abstract:: This dissertation is comprised of four studies on different elements of Populus biotechnology and genomic science: 1) growth improvement by recombinant DNA (rDNA) modification of gibberellin (GA) metabolism; 2) gene editing using zinc-finger nucleases (ZFNs); 3) induction of floral sterility by RNA interference (RNAi) of AGAMOUS (AG) gene homologs; and...

Metabolism of one carbon (C1) and methylated compounds in SAR11 bacteria

Creator:: Sun, Jing
Abstract:: SAR11 Alphaproteobacteria are the most abundant aerobic chemoheterotrophs in ocean surface waters. Previous studies have indicated SAR11 cells play an important role in marine carbon cycling and consume up to half of some common dissolved organic compounds, such as amino acids. During sequencing of the first SAR11 genome, genes for...

Analysis of coproporphyrinogen III oxidase in maize : the genes, their expression, and the localization of their products

Creator:: Williams, Pascale M.
Abstract:: Coproporphyrinogen III oxidase (CPX) is an enzyme involved in the biosynthesis of tetrapyrroles, catalyzing the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen IX. In bacteria and yeast this enzyme is cytosolic, in animals it is mitochondrial, and in each it functions to produce heme. However, in all plants investigated, the...

The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

Creator:: Smith, Daniel P.
Abstract:: Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...

Endogenous and antiviral RNA silencing pathways in Arabidopsis

Creator:: Chapman, Elisabeth J.
Abstract:: RNA silencing pathways are required for a wide variety of processes in most eucaryotes. In plants, small-interfering RNA (siRNA) arising from transposons and other repetitive sequences is associated with heterochromatin formation and maintenance. MicroRNAs and trans-acting siRNAs encoded at discrete loci function as negative regulators of gene expression by triggering...

Pyoluteorin as a signaling molecule regulating secondary metabolite production and transport genes in Pseudomonas fluorescens Pf-5

Creator:: Brodhagen, Marion L.
Abstract:: A major factor in the ability of Pseudomonas fluorescens Pf-5 to act as a biological control agent is its production of antibiotics, including pyoluteorin (PLT), 2,4-diacetylphloroglucinol (2,4-DAPG) and pyrrolnitrin (PRN). The data provided in this thesis demonstrate that the presence of any of these antibiotics in the extracellular milieu affects...

From ALS to Antibodies: New Techniques in Mass Spectrometry-Based Proteoform Characterization

Creator:: Meeuwsen, Joseph C.
Abstract:: Altogether, this dissertation highlights the value of mass spectrometry-based analysis of intact proteins for solving problems related to understanding disease mechanisms and developing new therapeutics. Mutations to the antioxidant enzyme Cu, Zn Superoxide Dismutase (SOD1) perturb protein structure in vivo to cause 2-5% of amyotrophic lateral sclerosis (ALS) cases. Metal-deficient...

Functional Characterization and Classification of Genes Essential to Flower Induction, Flower Development, and Seed Development in Populus and Eucalyptus

Creator:: Elorriaga, Estefania
Abstract:: This dissertation consists of four studies of Populus and Eucalyptus biotechnology and genomic science: 1) induction of floral sterility by tapetal expression of the ribonuclease Barnase in Populus; 2) CRISPR Cas9-mediated gene editing targeting LEAFY (LFY) and AGAMOUS (AG) homologs in Populus; 3) induction of floral sterility by CRISPR Cas9...
