Ancestral polymorphism and recent invasion of transposable elements in Drosophila species
(Biomed Central Ltd., 2012-07-23)
Background: During the evolution of transposable elements, some processes, such as ancestral polymorphisms and horizontal transfer of sequences between species, can produce incongruences in phylogenies. We investigated the ...
Ancestral polymorphism and recent invasion of transposable elements in Drosophila species
(Biomed Central Ltd., 2014)
Canonical P elements are transcriptionally active in the saltans group of Drosophila
(2004-07-01)
Up to now, investigations of expression and regulation of P transposable element have been almost exclusively carried out with the Drosophila melanogaster canonical P element. Analyzing eight species of the saltans group, ...
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 ...
Alteration of the reproductive patterns in drosophila melanogaster by effects of high concentrations of boron on in vitro cultured medium Alteración de los patrones reproductivos en drosophila melanogaster por efectos de altas concentraciones de boro en u
(Universidad de la Frontera, 2009)
The objective of this study was to evaluate the effects of boron (B) using as a biological model Drosophila malanogaster. Analizing specifically the responses over descendency to doses of 6,0 and 12 mg/L, comparing a control ...
