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 ...
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 ...
Alteration of the Reproductive Patterns in Drosophila melanogaster by Effects of High Concentrations of Boron on In Vitro Cultured Medium
(Sociedad Chilena de Anatomía, 2009)
A molecular linkage map for Drosophila mediopunctata confirms synteny with Drosophila melanogaster and suggests a region that controls the variation in the number of abdominal spots
(WILEY-BLACKWELLMALDEN, 2012)
The classic approach to gene discovery relies on the construction of linkage maps. We report the first molecular-based linkage map for Drosophila mediopunctata, a neotropical species of the tripunctata group. Eight hundred ...
Male-killing Spiroplasma naturally infecting Drosophila melanogaster
(Wiley-blackwellMaldenEUA, 2005)
A Mathematical Model of Communication between Groups of Circadian Neurons in Drosophila melanogaster
(Sage Publications, 2014-11)
In the fruit fly, circadian behavior is controlled by a small number of specialized neurons, whose molecular clocks are relatively well known. However, much less is known about how these neurons communicate among themselves. ...
