Download or read book Lateral Gene Transfer in Evolution written by Uri Gophna and published by Springer Science & Business Media. This book was released on 2013-07-20 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the phenomenon of lateral gene transfer has been known since the 1940's, it was the genomics era that has really revealed the extent and many facets of this evolutionary/genetic phenomenon. Even in the early 2000s with but a handful of genomes available it became clear that the nature of microorganisms is full of genetic exchange between lineages that are sometimes far apart. The years following this saw an explosion of genomic data, which shook the "tree of life" and also raised doubts about the most appropriate species concepts for prokaryotes. This book attempts to represent the many-fold contributions of LGT to the evolution of micro and, to an extent, macro-organisms by focusing on the areas where the Editor felt it had the largest impact: metabolic innovations and adaptations and speciation.

Available in PDF, EPUB and Kindle. Book excerpt: Provided here is an up-to-date survey of gene transfers in the main natural habitats, with a special reference to genetically engineered microorganisms.In the first of five sections technical approaches of gene transfer in the natural environment are developed. These emphasize the use of modernmethodologies for the detection of recombinant bacteria in natural waters and soil, using DNA or rRNA probes and PCR technology. The three following sections deal with various aspects of gene transfer in aquatic environments, terrestrial habitats and human and animal gut. These include transfer of plasmidic or chromosomal markers through either conjugation, mobilization, transformation or transduction processes. Also covered are factors influencing survival of cells harbouring the transferred genes in these environments. The last section is devoted to an examination of scientific and ethical problems related to the release of genetically engineered microorganisms.

Download or read book Modeling the Kinetics of Bacterial Horizontal Gene Transfer in Low nutrient Aquatic Environments written by Chad Crain and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The study presented in this dissertation focuses on characterizing the rates of horizontal gene transfer (HGT) by conjugation in Gram-negative bacteria under nutrient-limiting conditions. The HGT rates and frequencies of different Gram-negative mating pairs were evaluated and quantified experimentally. Escherichia coli S17-1 was used as a donor strain, while recipient bacteria were Acinetobacter calcoaceticus and E. coli DH5[alpha], Cupriavidus necator JMP134, Pseudomonas aeruginosa PAO1, Burkholderia vietnamiensis G4. A broad-host-range green fluorescence protein (GFP) reporter system, using plasmids pMMB190 and pRK-Km (a pRK415 derivative) was constructed for visual detection and quantification of HGT events under different conditions.The primary data generated in the various mating experiments were used as empirical input data to run a batch HGT kinetics model. The developed mathematical model was derived from a system of mass action rate expressions to predict the increase in transconjugant species under surface and planktonic mating conditions. The model is driven largely by unique intrinsic rate coefficients of gene transfer (k(z)) that were determined for different mating pairs. The nutrient-limiting conditions used in the experiments allowed for gene transfer kinetics to be observed and quantified, largely in the absence of growth, so that gene transfer would not be overestimated. The results of this study indicate that gene transfer varies considerably between donor and recipient mating pairs, and is markedly enhanced in surface-associated incubations ranging from 5.56 x 104 to 3.70 x 102 transconjugants per minute, compared to 2.8 x 102 to 1.56 x 101 per minute under planktonic conditions. The kinetics of gene transfer in most mating pairs appeared to lag at earlier time points ( 3 hours), but increased markedly after 8 hours for surface incubations. Isogenic mating pairs (e.g. E. coli) demonstrated much higher rates of gene transfer under both incubation conditions, despite possessing the slowest growth rates compared to non-isogenic mating pairs (e.g. E. coli with Cupriavidus necator JMP134, Pseudomonas aeruginosa PAO1 or Burkholderia vietnamiensis G4).The results of the various modeling simulations suggest that gene transfer kinetics using the developed mass-action-based model is sufficient for predicting the rate of gene transfer of a bulk mating population for different species when accounting for growth. The accuracy is driven by unique intrinsic rate terms (k(z)) that are expressed for individual mating pairs. Variability of k(z) terms was seen in short mating incubations, but these terms converged to uniform values at later times ( 6 hours). The uniform k(z) values provide accurate predictions of transconjugant increases during simulations, as confirmed by primary experimental data. The combination of k(z) terms along with transport equations can be reduced to a simplified two-equation model for evaluating the distribution and transport of transconjugant species in subsurface aquatic environments. Moreover, transport dynamics of mating pair species can be further characterized using confocal microscopy to generate real-time datasets. Based on the comparison between primary confocal data and simulations from the two-equation model, the Happel sphere-in-cell model is not predictive of species transport and distribution at pore-scale levels, because the model is far too idealized. Based on visual data generated with the HGT reporter system, single-cell gene transfer can be detected and quantified in real time under static and dynamic conditions and evaluated under nutrient-limiting conditions to confirm model predictions.

Download or read book Genetically Engineered Organisms Wildlife and Habitat written by National Research Council and published by National Academies Press. This book was released on 2008-11-03 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first commercial introduction of transgenic corn plants in 1995, biotechnology has provided enormous benefits to agricultural crop production. Research is underway to develop a much broader range of genetically engineered organisms (GEOs), including fish, trees, microbes, and insects, that could have the potential to transform fields such as aquaculture, biofuels production, bioremediation, biocontrol, and even the production of pharmaceuticals . However, biotechnology is not without risk and continues to be an extremely controversial topic. Chief among the concerns is the potential ecological effects of GEOs that interact with wildlife and habitats. The U.S. Geological Survey (USGS) is charged with providing scientific advice to inform federal agencies that manage wildlife and their habitats. USGS has identified biotechnology as one of its major challenges for future research. Seeing an opportunity to initiate a dialogue between ecologists and developers of GEOs about this challenge, the USGS and the National Research Council (NRC) held a two-day workshop in November of 2007, to identify research activities with the greatest potential to provide the information needed to assess the ecological effects of GEOs on wildlife and habitats. The workshop, designed to approach the research questions from a habitat, rather than transgenic organism, perspective, is summarized in this book.
Download or read book Aquatic Genomics written by N. Shimizu and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a scientific pursuit there is continual food for discovery and wonder. M. Shelley (1818) Genomic analysis of aquatic species has long been overshadowed by the superb activity of the human genome project. However, aquatic genomics is now in the limelight as evidenced by the recent accomplishment of fugu genome sequencing, which provided a significant foundation for comparative fish genomics. Undoubt edly, such progress will provide an exciting and unparalleled boost to our knowl edge of the genetics of aquatic species. Thus, aquatic genomics research has become a promising new research field with an impact on the fishery industry. It is notewor thy that the Food and Agriculture Organization (FAO) of the United Nations has projected that current global fisheries production will soon become insufficient to supply the increasing world population and that aquaculture has a great potential to fulfill that demand. This book, Aquatic Genomic. ~: Steps Toward a Great Future, was designed as a collection of advanced knowledge in aquatic genomics and biological sciences. It covers a variety of aquatic organisms including fish, crustaceans, and shellfish, and describes various advanced methodologies, including genome analysis, gene map ping, DNA markers, and EST analysis. Also included are discussions of many sub jects such as regulation of gene expression, stress and immune responses, sex differ entiation, hormonal control, and transgenic fishes.
