Repression of P element-mediated hybrid dysgenesis in Drosophila melanogaster.
Inbred lines derived from a strain called Sexi were analyzed for their abilities to repress P element-mediated gonadal dysgenesis. One line had high repression ability, four had intermediate ability and two had very low ability. The four intermediate lines also exhibited considerable within-line variation for this trait; furthermore, in at least two cases, this variation could not be attributed...
متن کاملP-element-induced male recombination and gene conversion in Drosophila.
A P-element insertion flanked by 13 restriction fragment length polymorphism (RFLP) marker sites was used to examine male recombination and gene conversion at an autosomal site. The great majority of crossovers on chromosome arm 2R occurred within the 4-kb region containing the P element and RFLP sites. Of the 128 recombinants analyzed, approximately two-thirds carried duplications or deletions...
متن کاملSites of P element insertion and structures of P element deletions in the 5' region of Drosophila melanogaster RpII215.
Several P element insertion and deletion mutations near the 5' end of Drosophila melanogaster RpII215 have been examined by nucleotide sequencing. Two different sites of P element insertion, approximately 90 nucleotides apart, have been detected in this region of the gene. Therefore, including an additional site of P element insertion within the coding region, there are at least three distinct ...
متن کاملDrosophila P element transposase induces male recombination additively and without a requirement for P element excision or insertion.
P element dysgenesis-associated male recombination in Drosophila was examined with a selective system focused upon a section of the third chromosome divided into eight recombination segments. Tests compared crossing over in the presence of none, one and two doses of P(delta 2-3)(99B), a non-mobile transposase source, in the absence of a mobilizable P element target in the genome. In the presenc...
متن کاملHybrid Element Insertion
It has previously been shown that the combination of two deleted Pelements in trans, one containing the left functional end and the second element the right functional end, can lead to high levels of male recombination. This finding strongly suggests that P-element, ends from different chromosomes can become associated, followed by “pseudo-excision.” We show that two different processes are inv...
