Transposable 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 کاملPopulation genomics of transposable elements in Drosophila.
Studies of the population dynamics of transposable elements (TEs) in Drosophila melanogaster indicate that consistent forces are affecting TEs independently of their modes of transposition and regulation. New sequencing technologies enable biologists to sample genomes at an unprecedented scale in order to quantify genome-wide polymorphism for annotated and novel TE insertions. In this review, w...
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-...
متن کاملDetection of transposable elements in Drosophila salivary gland polytene chromosomes by in situ hybridization.
In situ hybridization is particularly appropriate for mapping specific DNA sequences on polytene chromosomes of Drosophila and other dipterans. This technique is based on the recognition and binding of one labeled sequence (the probe) to homologous sequences on chromosomes fixed on a microscope slide. The probes are labeled with biotin or other nonradioactive products, and the probe signal can ...
متن کاملInterspecific hybridization as a genomic stressor inducing mobilization of transposable elements in Drosophila
Transposable elements (TEs) are DNA sequences able to be mobilized in host genomes. They are currently recognized as the major mutation inducers because of their insertion in the target, their effect on neighboring regions, or their ectopic recombination. A large number of factors including chemical and physical factors as well as intraspecific crosses have traditionally been identified as indu...
