The pathogens causing these infections can acquire antibiotic resistance genes in a process termed horizontal gene transfer (HGT). HGT is a common event in the human gut microbiome, that is, the microbial ecosystem of the human intestinal tract. HGT in the gut microbiome can occur via different...
5.6Horizontal Gene Transfer Genetic mutationscan occur in response to an environmental exposure, or during reproduction. In microbes, there is an additional mechanism forgeneticmutation: the acquisition of DNA in a process calledhorizontal gene transfer. Horizontal gene transfer (also known as l...
To confirm the possibility of such horizontal gene transfer from the cell culture medium, we repeated these experiments using goat serum instead of FBS (Fig.2). As noted in the experiments with FBS, mouse genomic DNA, mRNA, or plasmid DNA andE. coligenomic DNA were detected as expected (Fig...
This is the first example of ubiquitin being produced by a prokaryote.Transduction by bacteriophages is one mechanism by which horizontal gene transfer canoccur and can also be a useful tool for genetic manipulation. Fifteen potentially new B.fragilis-specific bacteriophages were isolated from filtered...
Our results suggest that the horizontal transfer of retrotransposons can occur through the incorporation of RNA intermediates delivered via EVs and may have important implications for the intercellular regulation of gene expression and gene function....
To explore the conditions for stabilization of microbial diversity, we developed a simple mathematical model consisting of two competing populations that could exchange a single gene allele via horizontal gene transfer (HGT). We found that, although in a fixed environment, with unbiased HGT, the sys...
Horizontal gene transfer may have helped to form the domain eukaryota, has caused antibiotic resistance to occur, and has allowed organisms to infect our bodies. Read Horizontal Gene Transfer | Definition, Mechanism & Examples Lesson Recommended for You Video: What Is Trisomy? - Definition & ...
The problem of horizontal transfer is not unique to cultural evolution. In biology, horizontal gene transfer (HGT) occurs in bacteria, which recombine by transferring part of the DNA from one microbe to another. Similar to linguistic borrowing, this violates the assumptions of tree-based phylogeneti...
These results confirm that the Mer operon is key to Hg tolerance, and the tolerance can be transferred to other low-tolerant strains via horizontal gene transfer. Fig. 10 Minimum inhibition concentration (MIC) assay shows the gain of Hg tolerance in LT strains transformed with plasmid from A...
Horizontal gene transfer (HGT), the movement of heritable materials between distantly related organisms, is crucial in eukaryotic evolution. However, the scale of HGT in choanoflagellates, the closest unicellular relatives of metazoans, and its possible roles in the evolution of animal multicellularity...
