Gene Transfer via Transformation in Soil/Sediment Environments “parasites”: bacteriophages can transport genes (transduction) and plasmids can promote DNA transfer during cell contact (conjugation). The third parasexual process is genetic transformation during which free DNA is taken up by cells. This DNA uptake is controlled by bacterial genes located on the

DNA Binding to Various Clay Minerals and Retarded Enzymatic Degradation of DNA in a Sand/Clay Microcd nucleic acids (for review see Stotzky 1986). In view of the evaluation of an environmental gene transfer by genetic transformation it is important to examine the interaction of free DNA with soil particles. It is our concept to start the examination by using microcosms with model soil and then gra

Characterization of Natural Transformation of the Soil Bacteria , and , by Chromosomal and Plasmid Dnes by free DNA among a natural microbial population requires several steps including (i) the release of functional DNA from donor cells, (ii) the persistence of extracellular DNA, (iii) the development of competence in the milieu of the natural environment, (iv) the uptake of free DNA into a compet

Interactions between Actinophage and their Streptomycete Hosts in Soil and the Fate of Phage Borne G, soil is rapidly colonized by growing mycelia, and the subsequent reduction of nutrients results in spore formation. The spore stage acts as a desiccation and phage-resistant dispersal mechanism. The combination of mycelial growth and dispersal of spores through soil are significant in the spread o

Steven Dymarkowski MD, PhD,Hilde Bosmans PhDison. Having in mind to use . as a containment system for the release of recombinant DNA in the environment, this bacteria was also used as a recipient in a study to establish a model system assaying the intergeneric transmission and expression of cloned genes in soil samples (Top et al. 1990).
