MAGGY is a gypsy-like LTR retrotransposon isolated from the blast fungus Pyricularia grisea (teleomorph, Magnaporthe grisea). We examined transposition of MAGGY in three P. grisea isolates (wheat, finger millet, and crabgrass pathogen), which did not originally possess a MAGGY element, and in two heterologous species of filamentous fungi, Colletotrichum lagenarium and P. zingiberi. Genomic Sout...

Insertional mutagenesis with a heterologous transposon provides a method to rapidly determine the molecular identity of mutated genes. The Drosophila transposon Mos1 can be mobilized to cause mutations in Caenorhabditis elegans (Bessereau et al. 2001); however, the mutagenic rate was initially too low for use in most forward genetic screens. To increase the effectiveness of Mos1-mediated mutage...

Transposition of insertion sequences (IS) is an enzyme-mediated process that only occurs in a minority of cells within a bacterial culture. Transposition is thus a rare event, but transposition frequency may vary depending on experimental conditions. For instance in a rich broth, IS elements are known to transpose during stationary phase but not during exponential growth. Using a reporter syste...

The transposition of EU law into national law is a significant part of the EU policy process. However, political scientists haven’t devoted to it the attention that it deserves. The author, a political scientist, construes transposition as a part of the wider process of policy implementation. Following implementation theory from the field of public policy, the article outlines three sets of fac...

Fortified Transposition Hypergroups appeared during the study of the theory of Formal Languages and Automata from the point of view of the hypercompositional structures theory. This paper studies the subhypergroups of these hypergroups and presents properties of their closed, symmetric, normal and reflexive subhypergroups.

The transposition and excision rates of the 412 retrotransposable element were estimated in five populations of Drosophila simulans differing in their average 412 copy numbers, which ranged from 2 to 54. The transposition rate was found to equal 1 x 10(-3) to 2 x 10(-3), independently of copy number. No excision was detected. These values eliminate autoregulation as a force maintaining copy num...

Transposition tables are a well-known method for pruning duplicates in heuristic search. This paper presents a detailed analysis of transposition tables for IDA*. We show that some straightforward implementations of IDA* with transposition tables (IDA*+TT) can result in suboptimal solutions being returned. Furthermore, straightforward implementations of IDA*+TT are not complete. We identify sev...

A local transposition flap can be used to close a large donor defect. This is a medially based transposition flap. Although the flap is randomly patterned in design, there is a rich supply of cutaneous perforators in this region of the trunk. These include anterior perforators from the internal thoracic artery, perforators from the superior and inferior epigastric arcades that can communicate a...
