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 کاملTransposable elements and the evolution of eukaryotic complexity.
Eukaryotic transposable elements are ubiquitous and widespread mobile genetic entities. These elements often make up a substantial fraction of the host genomes in which they reside. For example, approximately 1/2 of the human genome was recently shown to consist of transposable element sequences. There is a growing body of evidence that demonstrates that transposable elements have been major pl...
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 کاملTransposable Elements: Powerful Contributors to Angiosperm Evolution and Diversity
Transposable elements (TEs) are a dominant feature of most flowering plant genomes. Together with other accepted facilitators of evolution, accumulating data indicate that TEs can explain much about their rapid evolution and diversification. Genome size in angiosperms is highly correlated with TE content and the overwhelming bulk (>80%) of large genomes can be composed of TEs. Among retro-TEs, ...
متن کاملCompetition between transposable elements and mutator genes in bacteria.
Although both genotypes with elevated mutation rate (mutators) and mobilization of insertion sequence (IS) elements have substantial impact on genome diversification, their potential interactions are unknown. Moreover, the evolutionary forces driving gradual accumulation of these elements are unclear: Do these elements spread in an initially transposon-free bacterial genome as they enable rapid...
