Genetic Marker-Assisted Management of Virginia Sport Fishes
Molecular genetic markers can be used to assess genetic diversity, assign parentage, quantify inbreeding, and demonstrate structuring of populations across a system. Striped Bass Morone saxatilis, and Walleye Sander vitreus, are widely sought gamefishes in the Commonwealth of Virginia. Striped Bass …

Toward genetic marker-assisted improvement of aquaculture stocks
… quantitative trait loci (QTL) detection and marker-assisted selection (MAS) to genetic improvement of aquaculture species. Genes affecting aquaculture performance, or quantitative trait loci (QTLs}, can be mapped in relation to naturally-occuring genetic markers. Knowledge of linkages between …

Genetic marker analysis of three major carbohydrates in soybean seeds
… in soybean. However, little is known about the genetics of these quantitative traits. Recombinant inbred lines (RIL) were developed from the interspecific hybridization between a Glycine max breeding line (V71-370) and a Glycine soja plant introduction (PI407162). The 308 RILs, each parent, and …

Genetic marker frequency differences among strains of goldfish, Carassius auratus
… DNA fingerprinting were used to assess molecular genetic variation within and between strains of goldfish, Carassius auratus. Genetic variation observed both within and between strains was low using both methods. using isozyme markers, mean heterozygosity (0.0% - 4.4%) and percent polymorphic loci …

Identification of fecal pollution sources of karst waters by a combination of Bacteroidales genetic marker, bacterial indicators, and environmental variables
… were detected with a higher number of fecal biomarkers than rural spring systems. However, correlation between traditional bacterial indicators and fecal contamination determined by Bacteroidales-based MST was weak. Among all the environmental parameters examined, Escherichia coli, Cl-, and ORP …

Clarification of the Genetic Nature of Sugary Enhancer, an Endosperm Character in Sweet Corn
… in segregating populations. What is needed is a genetic marker which can readily and easily identify kernels containing se. To create a genetic marker system linked to the se gene, the chromosomal location of se in the maize (Zea mays L.) genome must first be determined.

Think ‘Zebra’
… date, all but one have at least one identified genetic marker. In 2021, researchers at the Medical University of South Carolina announced they may have found the first genetic marker for Hypermobile Ehlers-Danlos Syndrome (hEDS). This subtype is the most common and is commonly believed to be …

ΜΕΛΕΤΗ ΤΩΝ ΑΝΤΙΓΟΝΩΝ ΙΣΤΟΣΥΜΒΑΤΟΤΗΤΟΣ (HLA) ΣΤΟ ΣΥΝΔΡΟΜΟ ΑΔΑΜΑΝΤΙΑΔΗ-BEHCET
… LEADS TO THE CONCLUSION THAT POSSIBLY THERE IS A GENETIC BASIS WHICH PREDETERMINES THE SUSCEPTIBILITY OF ADAMANDIADES-BEHCET'S DISEASE AND ALSO THAT THE HLA-B5 ANTIGEN CONSTITUTES THE GENETIC MARKER OF THIS DISEASE.

Evolution in the genus Arum: a comparative analysis of morpohological and genetic variation.
Testing the correlation of morphological and genetic marker variation enables the investigation of evolutionary processes. Knowledge of evolutionary processes can be used to identify those morphological characters that could be used to produce evolutionary meaningful taxonomies. This thesis aims to …

The Population Genetics Of The Wood Frog, Rana Sylvatica, Across Its Geographic Range
<p>This study aimed to determine the level of genetic variation across the continental-wide range of the wood frog, Rana sylvatica. Levels of genetic differentiation between sampled populations were investigated as was the possible locations of glacial refugia for this species. DNA microsatellites …

An experimental investigation into the mechanisms of bacterial evolution
… (qPCR) to provide real-time enumeration of genetic marker abundance within bacterial populations. Second, I will focus on horizontal gene transfer in <em>E. coli</em> occurring through a process called conjugation. By fitting the qPCR data to a resource limited, logistic growth model, I will …

The Application of Molecular Genetics to the Conservation Management of Quolls, Dasyurus Species (Dasyuridae:Marsupialia)
… thesis I use two independent and highly variable genetic marker systems, the mitochondrial DNA (mtDNA) control region and nuclear microsatellites, to explore various aspects of conservation genetics relevant to the management of quolls. These aspects include an examination of the phylogenetic or …

Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
… was overcome by the use of an isolate-specific genetic marker. Black streaking in vines, a symptom commonly used as a method of disease assessment, was shown to be prone to false positives, as the fungus was not isolated from 65% of positive samples. Infected rootstock mother-vines were a source …

Structural variation at soybean loci regulating small RNAs and seed color
… RNA-Seq and genomic re-sequencing coupled with genetic marker information, a 129 bp deletion was discovered in a gene (Glyma.11G190900) encoding a member of the argonaute family of proteins (AGO5) that identifies the k1 mutation and leads to a non-functional protein.

High-resolution time series reveals differential behaviors of closely-related microbes in coastal communities
… of these cycles. From careful analyses of the genetics and behaviors of isolates we know that very closely related microbes can vary in their potential for growth, defense from predation, and ability to compete and cooperate for resources. However in surveys of the environment, most studies …
