Ferric Reductases And Transporters That Contribute To Mitochondrial Iron Homeostasis, Anshika Jain
Ferric Reductases And Transporters That Contribute To Mitochondrial Iron Homeostasis, Anshika Jain
Theses and Dissertations
Iron (Fe) is the fourth most abundant element in the Earth’s crust, yet the availability of Fe to plants is often limited. This is because in most soil types, Fe precipitates as ferric-oxyhydroxy complexes, making it unavailable for uptake by plants. While the mechanisms involved in Fe uptake from the soil are relatively well understood, the mechanisms involved in its further distribution to the aerial portion of the plant and to subcellular compartments are not fully understood. During Fe deprivation, plants up-regulate root Fe acquisition machinery. How plants sense Fe deprivation and tie the Fe status of the plant to …

Mitochondrial Replication From Embryogenesis To Early Adulthood, In Dui Species, Mytilus Galloprovincialis, Ellen Blenn Richardson
Theses and Dissertations
Eukaryotes typically inherit mitochondria strictly maternally. There are however a group of bivalve molluscs that inherit different mitochondrial genomes from each parent. The paternally inherited mtDNA (M-type) is localized to, and dominates over the maternally inherited mtDNA (F-type) in the gonads of the male offspring, but is not normally retained in any tissue of the female offspring. This process is termed Double Uniparental Inheritance (DUI). Using quantitative PCR (qPCR), this study examines mtDNA replication compared to total DNA replication through embryonic stages of development and into early adulthood of the DUI species, Mytilus galloprovincialis. Results indicate that up through the …
