Horizontal Transfer and Evolution of Prokaryote Transposable Elements in Eukaryotes
Horizontal transfer (HT) of transposable elements (TEs) plays a key role in prokaryotic evolution, and mounting evidence suggests that it has also had an important impact on eukaryotic evolution. Although many prokaryote-to-prokaryote and eukaryote-to-eukaryote HTs of TEs have been characterized, only few cases have been reported between prokaryotes and eukaryotes. Here, we carried out a compre...
متن کاملFactors that affect the horizontal transfer of transposable elements.
Transposable elements are characterized by their ability to spread within a host genome. Many are also capable of crossing species boundaries to enter new genomes, a process known as horizontal transfer. Focusing mostly on animal transposable elements, we review the occurrence of horizontal transfer and examine the methods used to detect such transfers. We then discuss factors that affect the f...
متن کاملPhylogenetic analysis supports horizontal transfer of P transposable elements.
Nucleotide sequence comparisons were used to investigate the evolution of P transposable elements and the possibility that horizontal transfer has played a role in their occurrence in natural populations of Drosophila and other Diptera. The phylogeny of P elements was examined using published sequences from eight dipteran taxa and a new, partial sequence from Scaptomyza elmoi. The results from ...
متن کاملMethods for detection of horizontal transfer of transposable elements in complete genomes
Recent advances in nucleic acid sequencing technology are creating a diverse landscape for the analysis of horizontal transfer in complete genomes. Previously limited to prokaryotes, the availability of complete genomes from close eukaryotic species presents an opportunity to validate hypotheses about the patterns of evolution and mechanisms that drive horizontal transfer. Many of those methods...
متن کاملTransposable elements and gene transformation in non-drosophilid insects.
This review summarizes recent data on the development of non-drosophilid insect transformation systems. The discussion focuses on one particular approach to developing transformation systems that relies on the use of short inverted repeat-type transposable elements analogous to that employed for Drosophila melanogaster transformation. Representatives from four families of short inverted repeat-...
