Metabolic engineering of cyanobacteria to optimize photobiological hydrogen production

Creator:: Luterra, Markael
Abstract:: Photobiological hydrogen production -- the use of photosynthesis to split water into hydrogen and oxygen -- presents an opportunity for efficient and large-scale solar biofuel development. One of the major challenges in this area is competition for reductant between the hydrogen-evolving hydrogenase enzyme and other metabolic pathways. In this work...

Advances in expression of heterologous protein products by Streptococcus gordonii

Creator:: Warren, Travis Kent
Abstract:: Streptococcus gordonii is a bacterial species that naturally colonizes the oral cavity of most healthy humans. It resides in the mouth as an adherent to dental surfaces and, with few exceptions, does not cause disease in individuals it inhabits. It possesses qualities that encourage its use as a vector to...

Genetics of partial incompatibility and improvement of haploid production in Hordeum vulgare L. x H. bulbosum L. crosses

Creator:: Chen, Fu-chiang and Chen, Fuqiang
Abstract:: The production of barley (Hordeum vulgare L.) haploids by crossing with H. bulbosum is a widely used tool in breeding and genetics. Certain barley genotypes have low seed set in this interspecific cross, a phenomenon known as partial incompatibility. Haploid production efficiency and gamete sampling are important issues with the...

Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

Stability of reporter gene expression and RNAi in transgenic poplars over multiple years in the field under vegetative propagation

Creator:: Li, Jingyi
Abstract:: Stable expression of transgenes is required for commercial uses of genetically engineered trees. To better understand the stability of transgene expression under field conditions, we studied transgene expression and RNA interference (RNAi)-induced transgene suppression in 2,480 transgenic poplars (460 transgene insertion events) over three years. Stability of expression was assessed...

Exploration of the feasibility of developing a winter hardy 'Marion' blackberry through genetic engineering

Creator:: Meng, Rengong
Abstract:: Experiments focusing on plant growth regulators’ concentrations and combination, mineral salt formulations and TDZ pretreatment formations were conducted to optimize in vitro shoot regeneration from leaf and petiole explants of 'Marion' blackberry. Optimum shoot formation was obtained when stock plants were incubated in TDZ pretreatment medium for three weeks before...

Factors affecting adventitious shoot formation and expression of microprojectile-introduced DNA in Douglas-fir cotyledons

Creator:: Goldfarb, Barry
Abstract:: Our goal was to develop knowledge that will enable insertion of foreign genes into Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] trees. This required improvement of a tissue culture system for producing adventitious shoots from cotyledons, and study of factors affecting gene delivery, expression, and analysis. Administering a short-duration, concentrated liquid pulse...

From the Oregon Wolfe Barley to fall-sown food barley : markers, maps, marker-assisted selection and quantitative trait loci

Creator:: Chutimanitsakun, Yada
Abstract:: Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...

Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

Creator:: Park, Eung-Jun
Abstract:: Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

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...

Silencing the Agrobacterium tumefaciens oncogenes

Creator:: Pitrak, Jennifer
Abstract:: Crown gall disease is an agricultural problem caused by the soil-borne bacterium, Agrobacterium tumefaciens. A. tumefaciens oncogenes cause transformed plant cells to overproduce the hormones, auxin and cytokinin. High hormone levels cause unorganized plant cell growth resulting in a gall. Control of crown gall disease is difficult because after plant...

Port-Orford-cedar and Phytophthora lateralis : grafting and heritability of resistance in the host, and variation in the pathogen

Creator:: McWilliams, Michael G.
Abstract:: Port-Orford-cedar (Chamaecyparis lawsoniana) is a forest tree native to a small area of Oregon and California. A root disease caused by Phytophthora lateralis causes widespread mortality of Port-Orford-cedar. This dissertation examines three important elements of the Port-Orford-cedar P. lateralis pathosystem related to breeding for disease resistance: use of resistant rootstocks...

Functional decreases in hydraulic and mechanical properties of field-grown transgenic poplar trees caused by modification of the lignin synthesis pathway through downregulation of the 4-coumarate:coenzyme A ligase gene

Creator:: Voelker, Steven L.
Abstract:: Society uses massive quantities of wood fiber in production of paper, and demand for fiber is projected to increase further as production of biofuels from fermentation of plant cellulosic materials increases. Because these end uses generally require the costly step of removing of lignin, wood with reduced or more easily...
