Carbon cycling and priming of soil organic matter decomposition in a forest soil following glucose additions

Creator:: Diaz, David D.
Abstract:: Soils are a globally significant carbon (C) pool and have the potential to respond to elevated CO2 and environmental changes through positive feedback cycles that enhance the turnover of soil organic matter (SOM). Understanding the mechanisms governing the turnover of SOM is particularly important for modeling the fate of C...

Identifying the Parameters for Wheat Pollen Electroporation Transformation

Creator:: Liu, Jiang
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world. It has been and continues to be one of the main sources of food for humans and animals. Although traditional wheat breeding has contributed greatly to the improvement of wheat both in productivity and biotic/abiotic stress...

Advances in the Analysis of Biogeochemical Interfaces: NanoSIMS to Investigate Soil Microenvironments

Creator:: Mueller, Carsten W., Weber, Peter K., Kilburn, Matt R., Hoeschen, Carmen, Kleber, Markus, and Pett-Ridge, Jennifer
Abstract:: Since a NanoSIMS high-resolution secondary ion mass spectrometry instrument was first used for cosmochemistry investigations over a decade ago, both interest in NanoSIMS and the number of instruments available have significantly increased. However, SIMS comes with a set of challenges that are of both technical and conceptual nature, particularly for...

Long-term Impacts of Nitrogen Fertilizer, Tillage and Crop Residue on Soil and Plant Nutrients in Winter Wheat Cropping Systems Under Dryland Conditions

Creator:: Shiwakoti, Santosh
Abstract:: Agricultural practices influence the nutrient dynamics of soil and plants, which may take more than a decade to be expressed in the drylands. The nutrient supplying capacity of soil is a crucial component of sustainable agriculture, and hence, this study can play an important role in policy making for the...

Microbial community dynamics associated with rhizosphere carbon flow

Creator:: Butler, Jessica L.
Abstract:: The cycling of root-deposited photo synthate (rhizodeposition) through the soil microbial biomass is widely recognized as a critical component of ecosystem functioning. Little is currently known about the flow of photosynthate through the microbial biomass however. My research goal was to examine if and how the flow of root-deposited photo...

Litter controls of microbial community composition and function in forest soils

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Comparative Genomics of Different Races of Columbia Root-knot Nematode and Development of Molecular Markers Linked to Corky Ringspot Resistance in Potato

Creator:: Hu, Shengwei
Abstract:: On a global scale, potato (Solanum tuberosum L.) plays an important role in tackling the threat of food insecurity due to its high yield and broad global acceptance. However, pathogens threaten potato production, causing direct yield loss and rendering potatoes tubers unmarketable. Breeding new cultivars that carry multiple resistances is...

Calcium Ion Transport via Seeping Flow Events through Epikarst Microfissures

Creator:: Windom, Lisa M.
Abstract:: Solute transport models in karst groundwater must consider variable and complex flow regimes. Within fissures less than 2 mm in aperture, during unsaturated flow events, seeping flow may flow as films or under capillary tension as a capillary rivulet. This project focuses on exploring the mass transport characteristics of seeping...

Development of a 10,000 Locus Genetic Map of the Sunflower Genome Based on Multiple Crosses

Creator:: Bowers, John E., Bachlava, Eleni, Brunick, Robert L., Rieseberg, Loren H., Knapp, Steven J., and Burke, John M.
Abstract:: Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across...
