Somatic excision of the Mu1 transposable element of maize.
The Mu transposons of the Robertsons's Mutator transposable element system in maize are unusual in many respects, when compared to the other known plant transposon systems. The excision of these elements occurs late in somatic tissues and very rarely in the germ line. Unlike the other plant transposons, there is no experimental evidence directly linking Mu element excision and integration. We h...
متن کاملInsertion and excision of the transposable element mariner in Drosophila.
The transposable element mariner is active in both germline and somatic cells of Drosophila mauritiana. Activity of the element is greatly enhanced in the presence of Mos1, a genetic factor identified as an autonomous copy of mariner. A strain of D. mauritiana containing Mos1 and other copies of mariner was used to initiate a screen for visible mutations. More than 20 mutations were obtained, i...
متن کاملCrawler, a novel Tc1/mariner-type transposable element in Aspergillus oryzae transposes under stress conditions.
A novel active transposable element, designated Crawler, has been isolated from an industrial strain (OSI1013) of Aspergillus oryzae as an insertion sequence within the niaD gene encoding nitrate reductase. It is 1290bp in length with imperfect terminal inverted repeats of 28bp and is flanked by 2bp (TA) target site duplications. It contains an open reading frame with no introns that encodes a ...
متن کاملAnalysis of a mutator activity necessary for germline transposition and excision of Tc1 transposable elements in Caenorhabditis elegans.
The Tc1 transposable element family of the nematode Caenorhabditis elegans consists primarily of 1.6-kb size elements. This uniformity of size is in contrast to P in Drosophila and Ac/Ds in maize. Germline transposition and excision of Tc1 are detectable in the Bergerac (BO) strain, but not in the commonly used Bristol (N2) strain. A previous study suggested that multiple genetic components are...
متن کاملTransposable element invasions
Transposable elements have an ongoing, largely parasitic interaction with their hosts. We are interested in the timescale of this interaction. In a recent publication, we have examined the sequence divergence between class II DNA transposons from mammalian genomes. We asked whether these sequences undergo a continuing process of turnover, keeping a family as an integrated whole, as members of t...
