A strain of the phytopathogenic bacterium Pseudomonas syringae
pv. phaseolicola, a pathogen of common bean Phaseolus vulgaris,
harbors a 150 kilobase pair (kb) plasmid pMC7105. In one strain,
LR719, pMC7105 is stably integrated in the bacterial chromosome.
Imprecise excision of the pMC7105 replicon has been shown to result
in the...
The Baculoviridae is a family of DNA viruses which are obligate
pathogens for a variety of insects. Baculovirus strains came to the
attention of researchers because they provided a nonchemical
alternative for the biological control of insect pests of agriculture
and forestry (Ignoffo, 1968); however, recently they have been studied...
Sequence-specific PCR markers were derived from one new and eight previously identified random amplified polymorphic DNA (RAPD) markers for the purpose of identifying grape (Vitis) rootstocks. The markers were developed because the RAPD assay was found to be inconsistent and the original RAPD markers unreliable. Southern hybridization analysis of the...
The objective of this dissertation is to introduce low-cost processing methods for the fabrication of ZnO transparent thin-film transistors (TTFTs). A novel method for depositing ZnO body layers via spin-coating of a zinc nitrate-based spin solution is presented. The processing conditions of spin-coated ZnO are optimized to produce continuous and...
A biosystematic investigation of Cryptogramma section
Cryptogramma in western North America has been directed towards
resolution of two separate taxonomic questions.
Results of this research support the hypothesis that a
previously undescribed diploid (2n = 30 II) taxon, C. cascadensis, is
present along with the common and widespread C. acrostichoides....
A novel method for detecting the peptidase activity of clinically relevant peptidases was investigated using solid-contact electrochemical polyion sensors under chronopotentiometric control. Complete instrumental control over ion-extraction was accomplished by incorporating a lipophilic electrolyte into the ion-selective membrane; the sensors had no intrinsic ion-exchange capabilities. The sensors were used to...
Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo
blight of Phaseolus vulgaris L., have been examined for
the presence of circular duplex deoxyribonucleic acid
(DNA)....
