The role of testis-specific gene expression in sex chromosome evolution of Anopheles gambiae
50 word max.) Gene expression in Anopheles gambiae shows a deficiency of testis expressed genes on the X chromosome associated with an excessive movement of retrogene duplication. We suggest the degeneration of sex chromosomes in this monandrous species is related to the biological and evolutionary forces of X-inactivation, dosage compensation and sexual antagonism.
متن کاملRole of testis-specific gene expression in sex-chromosome evolution of Anopheles gambiae.
Gene expression in Anopheles gambiae shows a deficiency of testis-expressed genes on the X chromosome associated with an excessive movement of retrogene duplication. We suggest that the degeneration of sex chromosomes in this monandrous species is likely the result of pressures from X inactivation, dosage compensation, and sexual antagonism.
متن کاملThe sex-determining gene doublesex in the fly Megaselia scalaris: conserved structure and sex-specific splicing.
The well-known sex-determining cascade of Drosophila melanogaster serves as a paradigm for the pathway to sexual development in insects. But the primary sex-determining signal and the subsequent step, Sex-lethal (Sxl), have been shown not to be functionally conserved in non-Drosophila flies. We isolated doublesex (dsx), which is a downstream step in the cascade, from the phorid fly Megaselia sc...
متن کاملSite-specific genetic engineering of the Anopheles gambiae Y chromosome.
Despite its function in sex determination and its role in driving genome evolution, the Y chromosome remains poorly understood in most species. Y chromosomes are gene-poor, repeat-rich and largely heterochromatic and therefore represent a difficult target for genetic engineering. The Y chromosome of the human malaria vector Anopheles gambiae appears to be involved in sex determination although ...
متن کاملSex-linked differentiation between incipient species of Anopheles gambiae.
Emerging species within the primary malaria vector Anopheles gambiae show different ecological preferences and significant prezygotic reproductive isolation. They are defined by fixed sequence differences in X-linked rDNA, but most previous studies have failed to detect large and significant differentiation between these taxa elsewhere in the genome, except at two other loci on the X chromosome...
