Abstract:
Many factors may explain why certain transposable elements (TEs) spread in some species and not others. On the one hand, they include processes that affect the rate of transposition, such as differences in the regulation of expression; on the other hand, they include characteristics of a genome that affect the consequences of transposition. In particular genome size may have an effect: a genome that is large due to non-essential repetitive DNA may be permissive for TE movement, as insertion events are less likely to be deleterious. Genome size may also help explain the pattern of TE distributi

Four aspects of horizontal genetic transfer during heterokaryon formation were examined in the asexual pathogen Fusarium oxysporum f.sp. cubense (Foe): 1) variability based on method of heterokaryon formation 2) differences in nuclear and mitochondrial inheritance 3) the occurrence of recombination without nuclear fusion 4) the occurrence of horizontal genetic transfer between distantly related isolates. The use of non- pathogenic strains of Fusarium oxysporum as biocontrol agents warrants a closer examination at the reproductive life cycle of this fungus, particularly if drag resistance or pa

Abstract:
Horizontal gene transfer (HGT) is one of the man driving forces of evolution in prokaryotes, and can also promote within-strain variation of bacterial species. The genomes of three previously sequenced Bacteroides fragilis strains, NCTC9343, 638R and YCH46 displayed evidence of extensive HGT, demonstrated by the presence of 28 divergent capsular polysaccharide-associated biosynthesis loci. The genomes of a further four B. fragilis strains, LS66, GNAB92, RD48 and BE1 were sequenced and analysed. Genomic comparisons of BE1 and GNAB92 with NCTC9343, 638R and YCH46 identified ten new divergent pol

Horizontal gene transfer (HGT) is now indisputably the predominant driving force, if not the sole force, behind speciation and the evolution of novelty in bacteria. Of all mechanisms of horizontal gene transfer (HGT), conjugation, the contact-dependent plasmid-mediated transfer of DNA from a bacterial donor to a recipient cell, is probably the most universal. First observed between bacteria, conjugation also mediates gene transfer from bacteria to yeast, plant and even animal cells.

Background: Genetic recombination is a driving force in genome evolution. Among viruses it has a dual role. For genomes with higher fitness, it maintains genome integrity in the face of high mutation rates. Conversely, for genomes with lower fitness, it provides immediate access to sequence space that cannot be reached by mutation alone. Understanding how recombination impacts the cohesion and dissolution of individual whole genomes within viral sequence space is poorly understood across double-stranded DNA bacteriophages (a.k.a phages) due to the challenges of obtaining appropriately scaled g

Bacteria's ability to pass entire genes between one another, a process called Horizontal Gene Transfer (HGT), has a major impact on bacterial evolution.

This thesis builds on that project, by improving our ability to identify gene families --- groups of genes in different strains that are related. Previously, similarity was measured only by comparing two genes' DNA sequences, ignoring their positions on the organism's DNA. Here, we lever

Recent studies suggest that horizontal gene transfer (HGT) plays an important role in niche adaptation in some eukaryotes and may be a major evolutionary force in unicellular lineages.

The dinoflagellates are a diverse group of mostly marine eukaryotes that have a propensity for both HGT and plastid endosymbiosis. Many dinoflagellates are predators and can ac

This study is the first to define the S. violaceoruber species group and shows that a number of named species including S. coelicolor, S. lividans and S. griseoruber, amongst others, to be the same species, forming a tight clade in a multigene analysis. Comparisons were made to strains of S. grisells to determine the overall similarity in the context of studying horizontal gene transfer of the streptomycin biosynthetic gene cluster. All type strains grouping with S. violaceorllber-are considered to be synonyms of this species. Phylogenetic analysis was done using the house-keeping genes 16S rR

Abstract:
Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Biology, 2006.<br>"February 2006."<br>Includes bibliographical references.<br>Horizontal gene transfer plays an important role in bacterial evolution. Although acquisition of foreign DNA can be beneficial to cells, it can also be detrimental. Therefore, cells that possess mechanisms to regulate horizontal gene transfer likely have a competitive advantage. Similarly, several mobile genetic elements possess mechanisms that regulate transfer. This regulation maintains stability and promotes dissemination of the element, thereby ensu

Abstract:
Experimental evolution has been used to investigate both general and specific evolutionary processes. More recently, it has also been used to resolve protein-protein interactions. Viruses assemble through a series of protein-protein interactions which must remain more favorable than any competing off-pathway reaction. By constructing chimeric viruses with genes or segments of genes from another species, foreign elements are introduced into this system of assembly. Characterization of the resulting chimeras provides information about which proteins interact, the protein-protein interacting inte
