Population genomics of transposable elements in Drosophila melanogaster.
Transposable elements (TEs) are the primary contributors to the genome bulk in many organisms and are major players in genome evolution. A clear and thorough understanding of the population dynamics of TEs is therefore essential for full comprehension of the eukaryotic genome evolution and function. Although TEs in Drosophila melanogaster have received much attention, population dynamics of mos...
متن کاملMolecular paleontology of transposable elements in the Drosophila melanogaster genome.
We report here a superfamily of "cut and paste" DNA transposons called Transib. These transposons populate the Drosophila melanogaster and Anopheles gambiae genomes, use a transposase that is not similar to any known proteins, and are characterized by 5-bp target site duplications. We found that the fly genome, which was thought to be colonized by the P element <100 years ago, harbors approxima...
متن کاملTransposable elements in natural populations of Drosophila melanogaster.
Transposable elements (TEs) are families of small DNA sequences found in the genomes of virtually all organisms. The sequences typically encode essential components for the replicative transposition sequences of that TE family. Thus, TEs are simply genomic parasites that inflict detrimental mutations on the fitness of their hosts. Several models have been proposed for the containment of TE copy...
متن کاملEffects of transposable elements on the expression of the forked gene of Drosophila melanogaster.
The products of the forked gene are involved in the formation and/or maintenance of a temporary fibrillar structure within the developing bristle rudiment of Drosophila melanogaster. Mutations in the forked locus alter this structure and result in aberrant development of macrochaetae, microchaetae and trichomes. The locus has been characterized at the molecular level by walking, mutant characte...
متن کاملCombinatorial Effects of Transposable Elements on Gene Expression and Phenotypic Robustness in Drosophila melanogaster Development
Embryonic patterning displays remarkable consistency from individual to individual despite frequent environmental perturbations and diverse genetic contexts. Stochastic influences on the cellular environment may cause transcription rates to fluctuate, but these fluctuations rarely lead to developmental defects or disease. Here we characterize a set of recessive alleles of the Toll pathway compo...
