Reversal of transposase gene orientation with respect to the nonidentical ends of IS50 strongly decreased IS50 transposition in both Dam- and Dam+ hosts. In either orientation, IS50 transposase expression was unaffected. These effects were independent of the surrounding DNA context. This shows that the efficiency of IS50 transposition is dependent on transposase gene orientation. The transposit...

Rhenium-catalyzed stereoselective transposition of allylic alcohols is reported.
Fragaria vesca was transformed with a transposon tagging construct harbouring amino terminally deleted maize transposase and EGFP (Ac element), NPTII, CaMV 35S promoter (P35S) driving transposase and mannopine synthase promoter (Pmas) driving EGFP (Ds element). Of 180 primary transgenics, 48 were potential launch pads, 72 were multiple insertions or chimaeras, and 60 exhibited somatic transposi...
Transposons are very valuable tools for genetic manipulation. However, the number of transposable elements that have been suitably adapted for experimental use is insufficient and the spectrum of heterologous hosts in which they have been deployed is restricted. To date, only transposons from animal hosts have been utilized in heterologous animal species and transposons of plant origin have bee...
Mutator-like transposable elements (MULEs) are widespread across fungal, plant and animal species. Despite their abundance and importance as genetic tools in plants, the transposition mechanism of the MULE superfamily was previously unknown. Discovery of the Muta1 element from Aedes aegypti and its successful transposition in yeast facilitated the characterization of key steps in Muta1 transpos...
Ulnar nerve transposition at the elbow is recommended to diminish nerve gaps during neurorrhaphy. We undertook a cadaver study to determine the gap distance that can be overcome by subcutaneous transposition at the elbow, evaluating lacerations 2.0 cm distal to the medial epicondyle and 2.0 cm proximal to the wrist crease. With a 100-g load on each nerve stump, gaps that could be overcome were ...
