Developing a Plant-Based Vaccine Against the Respiratory Syncytial Virus (Rsv)
… promoter and the terminator regions from PG were sequenced. BLASTn analysis reveals sequence homology to genes involved in ethylene production, pigment synthesis, and transcriptional control.

Identification of host proteins targeted by the flax rust effector protein AvrL567
… were truncated proteins. Two of them showed low sequence homology to fungal proteins, three putative interactors had low sequence homology to plant proteins and three had no sequence homology to any known protein. At the time of this project, neither the flax nor the flax rust genome had been …

A phylogenetic study of the genus Campylobacter
… by comparison of the partial 16S ribosomal RNA sequences determined using reverse transcriptase and oligonucleotide primers specific for regions in the 16S rRNA molecule. These species formed three distinct RNA sequence homology groups. We propose that the following species remain in the genus …

A study of DNA-DNA interactions during bacteriophage lambda integrative recombination
… either the top strand or the bottom strand sequences of the bacterial attachment site (attB) with or without base substitutions in the core region were chemically synthesized. Annealed oligodeoxynucleotide attB sites containing sequences with perfect base pairs or one mismatched base …

Sex-Associated Mitochondrial Genes: Tools for Understanding Unionid Reproduction and Development
… and F-ORF mitochondrial DNA were cloned and sequenced, and PCR was used to test for the presence of M-ORF and F-ORF genes within spermatozoa. F-ORF was not detected within sperm of V. pleasii despite previous reports of the protein product of F-ORF within sperm of V.ellipsiformis. M-ORF was …

Overexpression of the Hmp Gene in Esherichia Coli and Its Effect on Growth Rate
… for a protein that has extensive amino acid sequence homology with the N-terminal sequence of the Vitreoscilla sp. hemoglobin-like protein (Vhb), and the C-terminal has extensive sequence homology to the ferredoxin NADP⁺ reductase family. The hmp gene was shown to be regulated by oxygen …

Determination of Structure-Function Relationships in the Cytochrome Bo Oxidase From Escherichia Coli
… of oxidases with a high degree of amino acid sequence homology and other structural similarities. The identifying structural feature of this oxidase superfamily is the presence of a heme-copper binuclear center. Functionally, these enzymes have in common the ability to carry out the four …

Cloning and characterization of E2F6, a novel member of the E2F transcription factor family
… progression through the cell-cycle. Based upon sequence homology and functional properties, the E2F group can be subdivided into two subclasses (E2F1, 2, 3 versus E2F4 and 5). The work detailed in this study focuses on the cloning and characterization of a novel E2F family member, E2F6. E2F6 …

Investigation of XvSap promoters from the resurrection plant, Xerophyta viscosa
… The shortened promoters displayed no significant sequence homology to any other known plant promoter, besides XvPSap1. In addition to the shortened promoters, a newly discovered full length XvPSap2 promoter, showing a 56.41% homology with XvPSap 1 was also assessed in this study.

Developing synthetic, minimal promoters in Saccharomyces cerevisiae
… multi-gene pathway. Furthermore, their high sequence homology provides the organism the opportunity to perform homologous recombination resulting in undesirable gene deletions. For these reasons, there is a critical demand for short promoters with low sequence homology to the organism’s …

Molecular genetic manipulation and characterization of the high-potential chain of cyclic electron transport in Rhodobacter sphaeroides
… by a single amino-terminal, transmembrane helix. Sequence homology with dioxygenase subunits binding a spectrally similar 2FE-2S cluster, suggests the fully conserved residues of the cytochrome bc$\sb{1}$ and b$\sb{6}$f sequences ligating the iron-sulfur cluster may be the first and third …

Natural Selection on S-Linked Genes in Turnera (Passifloracease)
… in Turnera, average nucleotide diversity and sequence polymorphism measures were found to be elevated in two S-linked genes (AP2D and RNABP), suggesting the possible occurrence of balancing selection at these or closely-linked loci. Limited trans-species polymorphisms were identified in …

Development of A High-Throughput System For Screening of Anti-Prion Molecules
… My results show that regardless of sequence homology, prion strains are differentially responsive to known protein misfolding inhibitors. Continual optimization of PMCA towards a high-throughput system may be used not only for screening therapeutic agents but also for diagnosis.</p>

Molecular characterization of the binding site of nematode GABA-A receptors
… GABA receptor that has a relatively low overall sequence homology to mammalian GABA receptors but is very similar to the UNC-49 receptor found in the free living nematode Caenorhabditis elegans. However, the nematode receptors do exhibit different sensitivities to GABA which may be linked to …

The circadian Control of DNA end Resection
… and the repair of the lesion using a homologue sequence (Homology-Directed Repair, HDR). The choice between these two pathways is crucial for cell fitness and is controlled by an exquisite regulatory system. In this thesis, we uncovered a novel role for the circadian clock in the regulation of …

Upstream conserved sequence element that regulates TIM-3 induction in CD4+ T cell
… that regulatory DNA regions show nucleotide sequence homology between species, four conserved non-coding sequences (CNS -29, CNS -53, CNS -56 and CNS -63) were analyzed by comparison human TIM-3 upstream DNA sequences with mouse and cow counterparts. Only at CNS -63, H3K4 dimethylation that …

A Mutational Analysis of Bacteriophage Lambda Site-Specific Recombination (In Vitro, Dna-Dna Interaction, Protein, Oligonucleotide-Directed)
… of mutations within the 15 base "core" region of sequence homology demonstrated that homology dependent DNA-DNA interactions only occur within the 7-base "overlap" region where strand exchange occurs. In vitro recombination analyses with mutant att sites further demonstrated that the homology …

Comparative analysis of the promoters of the CyI-CyIIa-CyIIb actin gene cluster in the sea urchin Strongylocentrotus purpuratus
… transcription start site was subcloned and sequenced. Sites of protein-DNA interaction were identified using DNaseI footprinting. Comparisons of this data with that previously obtained for CyI and CyIIb showed that while CyI and CyIIb share an identical CArG (or serum response element) and …
