Interspecific comparison of the transformer gene of Drosophila reveals an unusually high degree of evolutionary divergence.
The transformer (tra) gene of Drosophila melanogaster occupies an intermediate position in the regulatory pathway controlling all aspects of somatic sexual differentiation. The female-specific expression of this gene's function is regulated by the Sex lethal (Sxl) gene, through a mechanism involving sex-specific alternative splicing of tra pre-mRNA. The tra gene encodes a protein that is though...
متن کاملResistance and relatedness on an evolutionary graph.
When investigating evolution in structured populations, it is often convenient to consider the population as an evolutionary graph-individuals as nodes, and whom they may act with as edges. There has, in recent years, been a surge of interest in evolutionary graphs, especially in the study of the evolution of social behaviours. An inclusive fitness framework is best suited for this type of stud...
متن کاملInterspecific DNA transformation in Drosophila.
A DNA fragment that includes the wild-type rosy (ry+) gene of Drosophila melanogaster has been introduced by microinjection into the germ line of the reproductively isolated species Drosophila simulans and incorporated into the D. simulans genome. Transformation was mediated by the transposable element P, which occurs in the genome of most natural populations of D. melanogaster but not in D. si...
متن کاملThe Essential Role of Vitellogenin Receptor in Ovary Development and Vitellogenin Uptake in Bactrocera dorsalis (Hendel)
The vitellogenin receptor (VgR) functions as an essential component in uptaking and transporting vitellogenin (Vg) in female adults, which is involved in ovary development and oviposition. This study aimed to clarify the molecular characteristics and function of VgR in the oriental fruit fly Bactrocera dorsalis (Hendel). Here, we identified the full-length of BdVgR (GenBank Accession No. JX4691...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
