A study of the interaction between alfalfa (Medicago sativa) and one of its fungal pathogens, Colletotrichum trifolii.
(2001)
The alfalfa/C. trifolii interaction follows a gene-for-gene interaction for race-cultivar specificity where in general, products of host resistance genes providing resistance to the fungus are interacting with direct or ...
Cloning, characterization, expression and localization of inosine-5'-monophosphate dehydrogenase (IMPDH) cDNA/mRNA in soybean (Glycine max) nodules.
(2000)
The technique of in situ hybridization was used to localize the IMPDH mRNA in soybean nodules. Mature nodules were fixed in 4% paraformaldehyde and 0.25% glutaraldehyde, dehydrated and embedded in Paraplast. Sections of ...
The reduction of uranium by sulfate-reducing bacteria in the terrestrial subsurface and a pure culture bacterium.
(2002)
The microbial reduction of uranium was investigated in a contaminated aquifer and with a pure culture model organism, Desulfovibrio vulgaris Hildenborough. The concentrations of Fe(III), U(VI), nitrate and sulfate were ...
THE ROLES AND MECHANISTIC FUNCTIONS OF NUCLEAR FACTOR Y TRANSCRIPTION FACTORS IN PLANTS
(2019-05)
Transcriptional regulation is a central component of biology whose importance cannot be overstated. From basal transcription of genes necessary for the physical make-up of a cell, to differential gene expression in response ...
Cell-cell interactions in Myxococcus xanthus.
(2004)
Myxococcus xanthus, a Gram-negative, rod-shaped, nonpathogenic soil bacterium has been used as a model organism for many years for research on developmental behavior such as multicellular morphogenesis, signal transduction. ...
ECOSYSTEM RESPONSES TO CLIMATE VARIABILITY AND MANAGEMENT PRACTICES: DROUGHT ASSESSMENT (REMOTE SENSING), FIELD MEASUREMENTS (EDDY COVARIANCE) AND MODELING (DNDC)
(2017-12-15)
Climate variability and management practices in isolation or in combination influence the properties of ecosystems and the flows of energy and materials through them. The goal of this dissertation is to better understand ...
Bacillus mojavensis and Bacillus subtilis require DNA or deoxyribonucleosides for anaerobic growth.
(2004)
Bacillus mojavensis strain JF-2 grows to an A600 of 0.8 to 1.0 in aerobic medium E but growth in this medium under strict anaerobic conditions is difficult to establish and replicate. Anaerobic growth of JF-2 was not ...
Cytosolic delivery of mutant forms of toxin B from Clostridium difficile facilitates characterization of the intracellular activities of large clostridal toxins.
(2002)
Clostridia are gram-positive spore-forming organisms responsible for a variety of diseases in both humans and animals Three species of Clostridia- Clostridium difficile, Clostridium sordellii and Clostridium novyi- produce ...
AN INVESTIGATION INTO THE INFLUENCE OF SUBSURFACE GEOCHEMISTRY ON MICROBIAL COMMUNITIES IN AN UNCONFINED CONTAMINATED AQUIFER
(2018)
Microorganisms account for ~ 90 gigatons of carbon in terms of global biomass and are important drivers of elemental cycling especially in oligotrophic subsurface environments. Subsurface ecosystems remain poorly characterized ...
