Gene transfer

There are many different reasons for gene transfer: for example, attempting to treat disease by supplying patients with therapeutic genes. There are also many possible ways to transfer genes.

Phylogenetic analyses indicate that Drosophila P elements have been transferred horizontally (Ref).
Horizontal transfer is also called lateral gene transfer and may account for 10 to 50% of all the genes in a bacterial or archaeal genome.

Gene transfer
Organisms can generally inherit genes in two ways. 1. By speciation (vertical gene transfer). Meaning from parent to offspring. 2. By Horizontal or lateral gene transfer.

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, ...

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 is invoked to explain how there is often extreme similarity between small portions of the genomes of two organisms that are otherwise very distantly related. Horizontal gene transfer seems to be common among many microbes.

By their very nature, phylogenetic trees hide any hybridization and lateral gene transfer (Woese 2002) that may have taken place. For these reasons, the proposed PhyloCode (see External Link below) does not assume a tree structure.

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 ...

(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.
