Geographic polymorphism of P element in populations of Drosophila sturtevanti
(Sociedade Brasileira de Genética, 2003-01-01)
The aim of this report was to detect full-sized P element sequences in eight strains of Drosophila sturtevanti populations from distant geographic regions and to assess the structural geographic variation among P element ...

Is the evolutionary history of the O-type P element in the saltans and willistoni groups of Drosophila similar to that of the canonical P element?
(Springer, 2007-12-01)
We studied the occurrence of O-type P elements in at least one species of each subgroup of the saltans group, in order to better understand the phylogenetic relationships among the elements within the saltans group and ...

Copy number of P elements, KP/full-sized P element ratio and their relationships with environmental factors in Brazilian Drosophila melanogaster populations
(Nature Publishing Group, 2003-12-01)
The P transposable element copy numbers and the KP/full-sized P element ratios were determined in eight Brazilian strains of Drosophila melanogaster. Strains from tropical regions showed lower overall P element copy numbers ...

ANTISYMMETRIC ELEMENTS IN GROUP RINGS II
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Let R be a commutative ring, G a group and RG its group ring. Let phi : RG -> RG denote the R-linear extension of an involution phi defined on G. An element x in RG is said to be phi-antisymmetric if phi(x) = -x. A ...
