Gene transfer agent
A phage-like agent from Rhodobacter capsulates species which can transfer DNA from the donor host to recipient cells.
Gene transfer Incorporation of new DNA into and organism's cells, usually by a vector such as a modified virus. Used in gene therapy.

[edit] Gene transfer
Organisms can generally inherit genes in two ways: from parent to offspring (vertical gene transfer), or by horizontal or lateral gene transfer, in which genes jump between unrelated organisms, ...
Gene transfer
The transfer of genes into a cell by any of a number of different methods available.

Gene
The term coined by Johannsen (1909) for the fundamental physical and functional unit of heredity.
Lateral Gene Transfer
Bacteria possess several methods for lateral gene transfer (also called horizontal gene transfer), the transmission of genes between individual cells.
Horizontal gene transfer: Transmission of DNA between species, involving close contact between the donor's DNA and the recipient, uptake of DNA by the recipient, and stable incorporation of the DNA into the recipient's genome.
Gene transfer from one cell to another brought about by a virus. The phenomenon was first described by Lederberg, Lederberg, Zinder and Lively (1952) with reference to Salmonella typhimurium, ...
Horizontal gene transfer The passing of pieces of DNA (plasmids) between species that provide a selective advantage in particular environments.
Gene therapy is an experimental form of treatment that uses gene transfer of genetic material into the cell of a patient to cure the disease.
This suggests that there is a significant level of "gene sharing" between bacterial species; this is called horizontal gene transfer.
The identification of similar sequences (including many genes) in two distantly related organisms, but not in other members of one of the clades, has led to the theory that these sequences were acquired by horizontal gene transfer.
Ballistic particle-mediated gene transfer. Complementary DNA molecules are adsorbed to gold particles and shot by a pressure gas jet into tissues or culture cells.

reticulation -- Joining of separate lineages on a phylogenetic tree, generally through hybridization or through lateral gene transfer. Fairly common in certain land plant clades; reticulation is thought to be rare among metazoans.
Transgenic pigs have also been produced by fertilizing normal eggs with sperm cells that have incorporated foreign DNA. This procedure, called sperm-mediated gene transfer (SMGT) may someday be able to produce transgenic pigs that can serve as a ...
F Factor (Fertility Factor): Transmissible plasmid (episome) in bacteria (such as E. coli) that acts as a sex factor. It is a circular DNA about 94 kb long. Conjugation and chromosomal gene transfer occur from F+ (male) to F- (female) bacterium.
