Transposable element-induced response to artificial selection in Drosophila melanogaster.
The P family of transposable elements in Drosophila melanogaster transpose with exceptionally high frequency when males from P strains carrying multiple copies of these elements are crossed to females from M strains that lack P elements, but with substantially lower frequency in the reciprocal cross. Transposition is associated with enhanced mutation rates, caused by insertion and deletion of P...
متن کاملTransposable element-induced response to artificial selection in Drosophila melanogaster: molecular analysis of selection lines.
Artificial selection lines for abdominal bristle score of Drosophila melanogaster established from P-M hybrid dysgenic crosses showed increases in selection response, heritability and phenotypic variance compared to similar lines started from nondysgenic crosses. To determine whether this increased genetic variance could be due to enhanced transposition of P elements following the dysgenic cros...
متن کاملThe transposable element mariner mediates germline transformation in Drosophila melanogaster.
A vector for germline transformation in Drosophila melanogaster was constructed using the transposable element mariner. The vector, denoted pMlwB, contains a mariner element disrupted by an insertion containing the wild-type white gene from D. melanogaster, the beta-galactosidase gene from Escherichia coli and sequences that enable plasmid replication and selection in E. coli. The white gene is...
متن کاملBehavior of a Drosophila melanogaster transposable element in Saccharomyces cerevisiae.
The Drosophila melanogaster transposable element 412 is transiently unstable in Saccharomyces cerevisiae when present on a freely replicating plasmid. The 412 element undergoes recombination to form two circular molecules, a 412 deletion plasmid and, presumably, a 412 circle. The 412 deletion plasmid contains a single long terminal repeat which most likely is the result of homologous recombinat...
متن کاملTargeting of P-Element Reporters to Heterochromatic Domains by Transposable Element 1360 in Drosophila melanogaster.
Heterochromatin is a common DNA packaging form employed by eukaryotes to constitutively silence transposable elements. Determining which sequences to package as heterochromatin is vital for an organism. Here, we use Drosophila melanogaster to study heterochromatin formation, exploiting position-effect variegation, a process whereby a transgene is silenced stochastically if inserted in proximity...
