Repetitive elements in the major histocompatibility complex (MHC) class I region of a teleost, medaka: identification of novel transposable elements
The repetitive elements of medaka (Oryzias latipes) are poorly characterized in spite of recent rapid progress in the medaka genome analysis. Here we report the characterization of the repetitive elements in the major histocompatibility complex (MHC) class I region, which spans about 400 kb and is one of the best characterized regions of the medaka genome. Microsatellite, low complexity regions...
متن کاملTransposable elements in Drosophila
Transposable elements (TEs) are mobile genetic elements that can mobilize within host genomes. As TEs comprise more than 40% of the human genome and are linked to numerous diseases, understanding their mechanisms of mobilization and regulation is important. Drosophila melanogaster is an ideal model organism for the study of eukaryotic TEs as its genome contains a diverse array of active TEs. TE...
متن کاملDetection of de novo insertion of the medaka fish transposable element Tol2.
Tol2 is a terminal-inverted-repeat transposable element of the medaka fish Oryzias latipes. It is a member of the hAT (hobo/Activator/Tam3) transposable element family that is distributed in a wide range of organisms. We here document direct evidence for de novo insertion of this element. A Tol2 clone marked with the bacterial tetracycline-resistance gene was microinjected into fertilized eggs ...
متن کاملEvidence for recent invasion of the medaka fish genome by the Tol2 transposable element.
Tol2 is a transposable element of the terminal-inverted-repeat class, residing in the genome of the medaka fish Oryzias latipes. The genus Oryzias contains more than 10 species for which phylogenetic relationships have previously been estimated. To infer the history of Tol2 in this genus we performed genomic Southern blots and PCR analyses of 10 of the species. It was revealed that Tol2 occurs ...
متن کاملTransposable genetic elements.
N atural selection, as Darwin rec ognized more than a centu ry ago, favors individuals and populations that acquire traits con ducive to survival and reproduction. The generation of biological variation, which gives rise to new and potentially advantageous combinations of genetic traits, is therefore a central requirement for the successful evolution of species in diverse and changing enviro...
