Using the psba Gene as a Measure in Determining the Phylogenetic Relationship among Bryophytes.
<p>The evolution of land plants, particularly the origin of land plants, had long been an issue of concern to biologists. Bryophytes were widely accepted as the first land plants to have emerged during the evolution of land plants (Kenrick 1997, Mishler 1994). But, the phylogeny of the groups …

On the phylogenetic relationship of South African species of Cladophora (Chlorophyta) based on the 26S (LSU) gene region
… The aims of this study were to provide a robust phylogenetic tree describing the relationship between members of the genus Cladophora and related taxa and to determine the origins of South Africa's estuarine species of Cladophora. After DNA extraction and cycle sequencing of products, sequences …

Calculating the structure-based phylogenetic relationship of distantly related homologous proteins utilizing maximum likelihood structural alignment combinatorics and a novel structural molecular clock hypothesis
Dendrograms establish the evolutionary relationships and homology of species, proteins, or genes. Homology modeling, ligand binding, and pharmaceutical testing all depend upon the homology ascertained by dendrograms. Regardless of the specific algorithm, all dendrograms that ascertain protein …

Isolation and Purification of Ribosomal Rnas of Euglena Gracilis; Their Evolutionary Significance as Determined by Oligonucleotide Catalogue Analysis
… This level of homology may indicate a phylogenetic relationship between this chloroplast and various prokaryotic organisms. Therefore, this study, involving the technique of oligonucleotide 'fingerprinting', was undertaken to study the phylogenetic relatedness of the Euglena chloroplast …

Phylogenetic Relationships and Character Evolution of the Neotropical Butterfly Genus Hamadryas (Nymphalidae: Biblidinae)
… within the genus, however no hypothesis of their phylogenetic relationship was proposed. The present dissertation provides a step further into the understanding of this fascinating group of butterflies not only by proposing the first phylogenetic hypothesis for the genus based on morphological and …

A study of the molecular variability of some South African isolates of tobacco necrosis virus
The relationship of various tobacco necrosis viruses, isolated from various crops and other sources in South Africa was determined. An isolate from avocado was chosen for partial characterisation to confirm that it was a member of the Necrovirus group of plant viruses. TNV was detected in potatoes …

Ecological Conservatism and Traits Predict Introduction Risk and Co-Occurrence for the Flora of Chicago
… We also found that traits such as life span, phylogenetic relationship, and wetland affinity were associated with C-score while breeding system and diaspore mass were not. In chapter 2, we examine what traits are associated with non-native introduction and post introduction invasion. We found …
