Molecular Phylogenetic Studies In Rosaceae, Christopher S. Campbell

University of Maine Office of Research Administration: Grant Reports

This project will investigate the evolutionary relationships within the large and important rose family. This group of plants contains numerous commercially valuable fruits (apples, pears, strawberries, cherries, peaches, plums, blackberries, and raspberries) and many horticulturally significant plants (roses, cotoneaster, lady's mantle, bridle-wreath, flowering quince, fire-thorn, cinqfoil, and others). Despite the large and important role that these plants play in our daily lives and scientific interest, we do not have a clear view of the evolutionary relationships of members of the family. A primary reason for this situation is that insufficient evidence has been accumulated to adequately address the problem. A …

Study Of Conidia Production And Transmission Of Beauverza Bassiana (Balsamo) Vuill. In Colorado Potato Beetle (Leptinotarsa Decemlineata), Silvia Fernandez

Electronic Theses and Dissertations

This work is an investigation of:( 1) mortality of the Colorado potato beetle (CPB), Leptinotarsa decemlineata (Say), under different modes of exposure to the pathogen Beauveria bassiana (Bals.) Vuill., (2) host and environmental factors affecting sporulation, production, and viability of B. bassiana conidia from infected cadavers of CPB larvae, and (3) transmission of the disease in CPB populations. The research leads to an improved understanding of the process of transmission of B. bassiana in CPB populations. This may enhance its use as a biological control agent for this pest insect. The highest rate of mortality of CPB larvae (77 percent) …

Characterization Of Biochelators, Membrane Redox Systems, And Quinone Reductases From Wood Degrading Basidiomycetes, Weihong Qi

Electronic Theses and Dissertations

Biodegradation of wood by brown rot fungi is dependent upon a non-enzymatic system involving Fenton chemistry. Iron biochelators with molecular weights lower than 1kD are important components in this process. Phenolate biochelators drive a hydroxyl radical generating Fenton reaction by reducing ferric iron. Biochelators may be mineralized or alternately, in some cases oxidized biochelators may be regenerated via a quinone redox cycle. Electron donors for this postulated regeneration have not been identified. Extracellular cellobiose dehydrogenase has also been found to drive the Fenton reaction by generating ferrous iron and hydrogen peroxide. This research compared the production of biochelators and the …
