Investigation of horizontal gene transfer in poplar/Amanita muscaria ectomycorrhizas.
Fine roots of forest trees form together with certain soil fungi symbiotic structures (ectomycorrhizas), where fungal hyphae are in intimate contact with plant cells. Due to root cell degeneration, plant DNA is released and could be taken up by the fungus. The possibility that horizontal gene transfer might result in a risk for the environment should be evaluated before a massive release of gen...
متن کاملHorizontal Gene Transfer
Horizontal gene transfer (HGT) is the movement of genetic information between organisms, a process that includes the spread of antibiotic resistance genes among bacteria (except for those from parent to offspring), fueling pathogen evolution. Many resistance genes evolved long ago in natural environments with no anthropogenic influence but these genes are now rapidly spreading to and among huma...
متن کاملInferring Horizontal Gene Transfer
Horizontal or Lateral Gene Transfer (HGT or LGT) is the transmission of portions of genomic DNA between organisms through a process decoupled from vertical inheritance. In the presence of HGT events, different fragments of the genome are the result of different evolutionary histories. This can therefore complicate the investigations of evolutionary relatedness of lineages and species. Also, as ...
متن کاملHorizontal gene transfer in plants.
Horizontal gene transfer (HGT) has played a major role in bacterial evolution and is fairly common in certain unicellular eukaryotes. However, the prevalence and importance of HGT in the evolution of multicellular eukaryotes remain unclear. Recent studies indicate that plant mitochondrial genomes are unusually active in HGT relative to all other organellar and nuclear genomes of multicellular e...
متن کاملHorizontal Gene Transfer in Evolution
The concept of horizontal or lateral gene transfer (the non-genealogical transmission of genetic material between organisms) was introduced in 1990s to explain the observed incongruence in phylogenetic reconstructions using different genes. Today, horizontal gene transfer is accepted as an important force modulating evolution of Bacteria, Archaea and unicellular eukaryotes, and evidence is risi...
