Utilizing Mitotalens To Investigate Large Repeats In The Arabidopsis Thaliana Mitochondrial Genome, Cambelle Johnson
Honors Theses
Mitochondria are a silly place to store the genetic code. In spite of the ever-present threat of oxidative DNA damage, plant mitochondrial genomes are expansive in size and include noncoding repeat sequences, a small number of which are greater than 1kilobase (kb), known hereafter as “large repeats” (LR). This theme of one or more large repeat pairs is shared across most flowering plants, lending to the belief that they somehow contribute to the plant’s fitness. These repeats exhibit high rates of rearrangement and recombination. Studying repeats in vivo could have large scale implications in hybrid crop production enhancement including eliminating …
Exploring Gene Expression Patterns For Resilient Maize Lines Under Nitrogen Stress, Alice Guo
Exploring Gene Expression Patterns For Resilient Maize Lines Under Nitrogen Stress, Alice Guo
Honors Theses
Nitrogen plays a major role in the proper growth and development of maize and is therefore essential to crop production, being the most critical nutrient for achieving optimal yield. In previous field and greenhouse studies, we have found maize lines that differ in their resiliency to nitrogen stress. To identify the potential genomic regions associated with the differences in nitrogen deficiency resilience, Genome-Wide Association Studies (GWAS) were conducted. Based on a previous study, the most consistently resilient maize inbred lines within the Goodman-Buckler diversity panel have been identified as the lines A619 and A661, while the non-resilient inbred lines have …
Targeting Transgenic Proteins To The Mitochondria In Plants, Susan Qudus, Jeffrey P. Mower
Targeting Transgenic Proteins To The Mitochondria In Plants, Susan Qudus, Jeffrey P. Mower
Honors Theses
Cytoplasmic male sterility (CMS) in plants can convert an individual into female through sterilization of the male reproductive parts, creating an inability to produce functional pollen. In nature, this is advantageous for genetic diversity and producing progeny with unique genes that may be beneficial in evolution. For agriculture, this method is preferential for selection of desirable traits in crops when cross breeding. CMS is typically caused by genes in the mitochondrial DNA (mtDNA), such as novel open reading frames (ORFs) that form after imperfect repair of double-stranded breaks in the mtDNA. Specific CMS genes vary among various plant species. It …
Inheritability Of Ciprofloxacin-Induced Mitochondrial Mutations From Parental To Offspring Generation Using Quantitative Polymerase Chain Reaction, Rose Mccoy
Honors Theses
In all eukaryotes, mitochondria are known as the powerhouse of the cell (Siekevitz, 1957). In plants, however, their mitochondrial genome is especially strange. Plant mitochondrial genomes are extremely large and contain both linear and circular subgenomic DNA fragments. Plant mitochondrial genomes undergo a significant amount of mutations in the form of rearrangements. However, it is not known how often these rearrangements are inherited by the next generation. It is thought that plant cells that are still dividing have higher rates of DNA repair, such as double-strand break repair, to ensure the quality of that plant lineage. As follows, it is …
Genetic Diversity And Distinctness Of Wild Nebraska Hops And Hop Cultivars (Humulus Lupulus L.), Megan Franklin
Genetic Diversity And Distinctness Of Wild Nebraska Hops And Hop Cultivars (Humulus Lupulus L.), Megan Franklin
Honors Theses
Background Commercial hop (Humulus lupulus) cultivars that are being grown in the Midwest are not performing as successfully as when they are grown in the Pacific Northwest, the region to which they are adapted. To increase adaptation to the Midwest environment, one strategy is to draw from the genetic pool of wild native Midwest hops, which have developed genes that allow them to grow successfully in this environment. Wild hop plants that are genetically distinct from commercial cultivars are likely to have more adaptations, such as pest/disease resistance and drought tolerance, which can be bred into commercial lines. The …
