Transposable elements and the evolution of eukaryotic genomes.
W hen transposable elements (TEs) were discovered in maize by Barbara McClintock 50 years ago they were regarded as a curiosity; now they are known to be the most abundant component of probably all eukaryotic genomes. They account for almost 50% of the human genome and 70% of the genomes of some grass species, including maize. As such, they make up the vast majority of the output of genome sequ...
متن کاملEvolution and Diversity of Transposable Elements in Vertebrate Genomes
Transposable elements (TEs) are selfish genetic elements that mobilize in genomes via transposition or retrotransposition and often make up large fractions of vertebrate genomes. Here, we review the current understanding of vertebrate TE diversity and evolution in the context of recent advances in genome sequencing and assembly techniques. TEs make up 4-60% of assembled vertebrate genomes, and ...
متن کاملEvolution and consequences of transposable elements.
Recent studies on transposable elements (TEs) have shed light on the mechanisms that have shaped their evolution. In addition to accumulating nucleotide substitutions over evolutionary time, TEs appear to be especially prone to genetic rearrangements and vertical transmissions across even distantly related species. As a consequence of replicating in host genomes, TEs have a significant mutation...
متن کاملRoadmap for annotating transposable elements in eukaryote genomes.
Current high-throughput techniques have made it feasible to sequence even the genomes of non-model organisms. However, the annotation process now represents a bottleneck to genome analysis, especially when dealing with transposable elements (TE). Combined approaches, using both de novo and knowledge-based methods to detect TEs, are likely to produce reasonably comprehensive and sensitive result...
متن کاملTransposable elements: powerful facilitators of evolution.
Transposable elements (TEs) are powerful facilitators of genome evolution, and hence of phenotypic diversity as they can cause genetic changes of great magnitude and variety. TEs are ubiquitous and extremely ancient, and although harmful to some individuals, they can be very beneficial to lineages. TEs can build, sculpt, and reformat genomes by both active and passive means. Lineages with activ...
