Sentences with phrase «bacterial gene transfer»

Not exact matches

«Recombinant DNA technology», «DNA cloning», «molecular cloning» or «gene cloning» all describe the process of transferring a DNA fragment from one organism to a self - replicating genetic element (a cloning vector) such as a bacterial plasmid, enabling the fragment to be propagated in an alien host.

They note that targeting inflammation to treat infections offers an advantage over antibiotic therapy, as the former hinders gene transfer and the evolution of pathogens, while the latter promotes bacterial evolution and, ultimately, antibiotic resistance.

Three options are on the table: tweak cereals so that they form symbiotic partnerships with rhizobia as legumes do; colonise cereal roots with other types of nitrogen - fixing bacteria; or transfer the bacterial genes that make fertiliser directly into the crop plants.

This information may help to predict which other bacterial species might participate in this form of gene transfer, and to identify just how widespread the phenomenon is.

Wick continues: «Our study shows that fungal hyphae not only provide soil bacteria with an excellent infrastructure, but also a potential hot spot for bacterial horizontal gene transfer.

«Antibiotics don't promote swapping of resistance genes: Bacterial resistance spreads through population dynamics, not an increase in gene transfers.»

Bacteria share DNA with other organisms with which they come into contact, so an antibiotic - resistant gene can transfer from one type of bacterium to another, and a bacterial cell can become resistant to numerous antibiotics at once.

Their research, published in January, shows that bacteriophages can rapidly accelerate the evolution of human pathogens by transferring genes from one bacterial species to another.

You are what you eat: a gene transfer ratchet could account for bacterial genes in eukaryotic nuclear genomes.

Phylogenomic analysis identifies evidence for lateral gene transfer of bacterial genes into the E. histolytica genome, the effects of which centre on expanding aspects of E. histolytica's metabolic repertoire.

Horizontal transfer of genes of bacterial origin has contributed to some of the metabolic differences in these parasites, and a number of novel potential drug targets have been identified.
