A substantial proportion of the genome of many species is derived from transposable
elements (TEs). Moreover, through various self-copying mechanisms, TEs continue to …

Transposable elements (TEs) are selfish genetic elements that mobilize in genomes via
transposition or retrotransposition and often make up large fractions of vertebrate genomes …

Background Sequencing technology and assembly algorithms have matured to the point
that high-quality de novo assembly is possible for large, repetitive genomes. Current …

Horizontal transfer (HT) of genetic material is central to the architecture and evolution of
prokaryote genomes. Within eukaryotes, the majority of HTs reported so far are transfers of …

Abstract The 19th annual Database Issue of Nucleic Acids Research features descriptions of
92 new online databases covering various areas of molecular biology and 100 papers …

The increase of publicly available sequencing data has allowed for rapid progress in our
understanding of genome composition. As new information becomes available we should …

In eukaryotes, genome size correlates little with the number of coding genes or the level of
organismal complexity (C-value paradox). The underlying causes of variations in genome …

Although both are salient features of genomes, at first glance ribosomal DNAs and
transposable elements are genetic elements with not much in common: whereas ribosomal …

Yarrowia lipolytica, an oleaginous yeast, is capable of accumulating significant cellular mass
in lipid making it an important source of biosustainable hydrocarbon-based chemicals. In …

Background The genomes of eukaryotes vary enormously in size, with much of this diversity
driven by differences in the abundances of transposable elements (TEs). There is also …
