Genetic diversity in Neospora caninum
… disorders and death in dogs. Biological diversity within the species N. caninum isolates has not been studied in detail. Limited differences were reported using several genetic approaches such as sequencing of ribosomal DNA. Mini- and microsatellite DNA markers have recently been reported …

Genetic diversity of Anopheles mosquitoes
This thesis presents two projects related to the genetic diversity of Anopheles mosquitoes. The first project concerns the development and application of sequence based species assignment methods for any species in the genus. The second project discusses the population structure of the major …

Genetic diversity of midwestern oat germplasm
… segregates per trait and generalized genetic variance were calculated for each mating. Four measures of genetic distance between the parents were calculated: geneological distance, Euclidean distance based upon principal components, and the distance measures proposed by Hanson and …

Genetic diversity of the chB6 alloantigen
… acid translation. These results suggest greater genetic diversity of the chB6 locus than previously appreciated. Furthermore, rt-PCR was used to clone the turkey homologue of chB6. The results presented here are the beginnings of a larger study to examine chB6’s role in B cell development that …

Causes and consequences of genetic diversity in pinnipeds
The rise of empirical population genetics and more recently the genomic revolution have given us the tools to explore completely new questions in ecology and evolution. Based on only a single temporal sample of individuals, genetics now allows us to glimpse into the demographic history of a species …

Effects of Culverts on Brook Trout Genetic Diversity
… maximize spawning and growth. Brook trout were genetically analyzed using a suite of 13 microsatellite loci above 7 culverts with varying levels of passability classified through a physical protocol. While most sites were not found to have losses in genetic diversity, populations above culverts …

Genetic Diversity and Camptothecin Variation in Camptotheca Decaisne
… objectives of this study are (1) to reveal the genetic diversity of Camptotheca and to identify taxa with RAPD markers; (2) to determine the camptothecin (CPT) variations within and among different populations and taxa, with tissues, season, and age; and (3) to determine the effects of …

Genetic diversity of African isolates of Toxoplasma gondii
… the current research is to analyse thelevel of genetic variation among local African T. gondii isolates in relation to theirphenotype (genotype phenotype relationships). In this study, multi-locus nested PCRsequence analysis of seven Ugandan T. gondii isolates was applied using nine …

Genetic diversity and population structure of Vaccinium vitis-idaea
Developing an understanding of the levels of diversity present at stages across the domestication continuum is key to retaining, or eventually introducing, diversity into domesticated plant lineages. There are special challenges associated with achieving this for perennial crops and their wild …

Investigation of Swine Influenza Virus Genetic Diversity and Evolution
… in epitopes, also occurs with influenza viruses. Genetic and antigenic analysis of SIV identified neutralizationresistant isolates which contained a conserved N144 in the hemagglutinin (HA) gene present only in neutralization-resistant strains (chapter 3). N144 lies in a predicted Nlinked …

Marker development and genetic diversity in saccharum and miscanthus
… that hinders genomic their research. For genetic mapping and genome assembly, a large number of DNA markers are needed. Due to the relatedness of these two species, markers can be designed that work in them both. Chapter one deals with an SSR marker analysis in sugarcane, and Chapter 2 …

Metabolomic profiles of Oryza sativa and influence of genetic diversity
… is a useful tool to assess the influence of genetics on total metabolite variation in the cooked grain. Cooked rice metabolite profiles for 10 diverse varieties were determined using ultra performance liquid chromatography coupled to mass spectrometry (UPLC-MS) on aqueous-methanol extracts. A …

Analysis of genetic diversity of Melampsora larici-populina in Iceland
Ræktun alaskaaspar á Íslandi hófst árið 1944 og hefur hún reynst það tré sem skilar hröðustum vexti hérlendis og mestum afköstum við kolefnisbindingu. Fram til ársin 1999 var alaskaösp nánast laus við skaðvalda en þá greindist asparryð, Melampsora larici-populina í fyrsta sinn hérlendis. …

Mining the Genetic Diversity of the Pathogenic Protozoan, Neospora caninum
… underlying question therefore, is what is the genetic basis of virulence within the species, and consequently, how can such information be exploited in vaccine development? Thus far, conventional techniques have been employed to study the intraspecies genetic diversity associated with 𝘕. …

Genetic Diversity in Native and Invasive <i>Rubus </i>(Rosaceae)
… species are an increasing threat to biological diversity as well as a leading cause of recent species’ extinctions. Invasives spread quickly and efficiently, and the U.S spends millions of dollars annually in the control and eradication of these species. More information is necessary in order to …

Phenotypic and Genetic Diversity in the Sea Urchin Lytechinus Variegatus
<p>Diversity in coloration is a common phenomenon in marine invertebrates, although the ecological significance of the diversity is often unknown. Patterns of geographic variability, particularly with respect to color phenotypes, are evident in many organisms and may provide visual evidence of …
