Novel transposable elements from Anopheles gambiae

An active transposable element, Herves, from the African malaria mosquito Anopheles gambiae.

Transposable elements have proven to be invaluable tools for genetically manipulating a wide variety of plants, animals, and microbes. Some have suggested that they could be used to spread desirable genes, such as refractoriness to Plasmodium infection, through target populations of Anopheles gambiae, thereby disabling the mosquito's ability to transmit malaria. To achieve this, a transposon mu...

Insertion polymorphism of transposable elements and population structure of Anopheles gambiae M and S molecular forms in Cameroon.

The insertion polymorphism of five transposable element (TE) families was studied by Southern blots in several populations of the M and S molecular forms of the mosquito Anopheles gambiae sensu stricto from southern Cameroon. We showed that the mean TE insertion site number and the within-population insertion site polymorphism globally differed between the M and S molecular forms. The compariso...

Conserved boundary elements from the Hox complex of mosquito, Anopheles gambiae

The conservation of hox genes as well as their genomic organization across the phyla suggests that this system of anterior-posterior axis formation arose early during evolution and has come under strong selection pressure. Studies in the split Hox cluster of Drosophila have shown that proper expression of hox genes is dependent on chromatin domain boundaries that prevent inappropriate interacti...

Transposable element dynamics of the hAT element Herves in the human malaria vector Anopheles gambiae s.s.

Transposable elements are being considered as genetic drive agents for introducing phenotype-altering genes into populations of vectors of human disease. The dynamics of endogenous elements will assist in predicting the behavior of introduced elements. Transposable element display was used to estimate the site-occupancy frequency distribution of Herves in six populations of Anopheles gambiae s....
