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 کاملTransposable Elements: No More 'Junk DNA'
Since the advent of whole-genome sequencing, transposable elements (TEs), just thought to be 'junk' DNA, have been noticed because of their numerous copies in various eukaryotic genomes. Many studies about TEs have been conducted to discover their functions in their host genomes. Based on the results of those studies, it has been generally accepted that they have a function to cause genomic and...
متن کاملDo transposable elements really contribute to proteomes?
Recent studies indicate that the initial classification of transposable elements (TEs) as 'useless', 'selfish' or 'junk' pieces of DNA is not an accurate one. TEs seem to have complex regulatory functions and contribute to the coding regions of many genes. Because this contribution had been documented only at transcript level, we searched for evidence that would also support the translation of ...
متن کاملEpigenetic regulation of Mammalian genomes by transposable elements.
Transposable element (TE) sequences make up a substantial fraction of mammalian genomes and exert a variety of regulatory influences on mammalian genes. We explore the contributions of TEs to the epigenetic mechanisms that regulate mammalian genomes, emphasizing nucleosome positioning and epigenetic histone modifications. A link between TEs and epigenetics rests on the fact that underlying gene...
متن کاملIdentification of transposable elements using multiple alignments of related genomes.
Accurate genome-wide cataloging of transposable elements (TEs) will facilitate our understanding of mobile DNA evolution, expose the genomic effects of TEs on the host genome, and improve the quality of assembled genomes. Using the availability of several nearly complete Drosophila genomes and developments in whole genome alignment methods, we introduce a large-scale comparative method for iden...
