Transposable elements and the plant pan-genomes.
The comparative sequencing of several grass genomes has revealed that transposable elements are largely responsible for extensive variation in both intergenic and local genic content, not only between closely related species but also among individuals within a species. These observations indicate that a single genome sequence might not reflect the entire genomic complement of a species, and pro...

متن کاملPlant Transposable Elements: Evolution Their Role in
Transposable elements (TE) are natural constituents of plant genomes. However, their presence only becomes apparent if they become dislodged from their resident positions in the genome and transpose into another gene, thereby inducing a mutation. Such TE-induced mutations are somatically unstable because they revert to wild type and hence reconstitute the expression of the mutated gene. The fre...
متن کاملPerspective : Transposable Elements , Parasitic Dna , and Genome
The nature of the role played by mobile elements in host genome evolution is reassessed considering numerous recent developments in many areas of biology. It is argued that easy popular appellations such as ‘‘selfish DNA’’ and ‘‘junk DNA’’ may be either inaccurate or misleading and that a more enlightened view of the transposable element-host relationship encompasses a continuum from extreme pa...
متن کاملTransposable elements and host genome evolution.
Several recent reports have challenged the idea that transposable elements (TEs) are mainly 'selfish' or 'junk' DNA with little importance for host evolution. It has been proposed that TEs have the potential to provide host genomes with the ability to enhance their own evolution. They might also be a major source of genetic diversity, allowing response to environmental changes. Because the rela...
