Different mechanisms of X-ray irradiation-induced male and female sterility in Aedes aegypti

Tags: , , , ,
Zhang, H., Trueman, E., Hou, X. et al.,  BMC Biology,  21. 2023.
Aedes aegypti (Ae. aegypti) is the major vector that transmits many diseases including dengue, Zika, and filariasis in tropical and subtropical regions. Due to the growing resistance to chemical-based insecticides, biological control methods have become an emerging direction to ...

Tags: ,
Shih-Che Weng, Igor Antoshechkin, Eric Marois, Omar S. Akbari,  PLoS Genetics,  2023.
Only female mosquitoes consume blood giving them the opportunity to transmit deadly human pathogens. Therefore, it is critical to remove females before conducting releases for genetic biocontrol interventions. Here we describe a robust sex-sorting approach termed SEPARATOR ...

Field trials and modelling studies suggest that elimination of dengue transmission may be possible through widespread release of Aedes aegypti mosquitoes infected with the insect bacterium Wolbachia pipientis (wMel strain), in conjunction with routine dengue control activities. ...

Gene drives for the extinction of wild metapopulations

Tags: ,
Jason W. Olejarz, Martin A. Nowak,  Journal of Theoretical Biology,  2023.
Population-suppressing gene drives may be capable of extinguishing wild populations, with proposed applications in conservation, agriculture, and public health. However, unintended and potentially disastrous consequences of release of drive-engineered individuals are extremely ...

A toxin-antidote system contributes to interspecific reproductive isolation in rice

Breakdown of reproductive isolation facilitates flow of useful trait genes into crop plants from their wild relatives. Hybrid sterility, a major form of reproductive isolation exists between cultivated rice (Oryza sativa) and wild rice (O. meridionalis, Mer). Here, we report the ...

Aedes aegypti microbiome composition covaries with the density of Wolbachia infection

Tags: ,
Jane Pascar, Henry Middleton & Steve Dorus,  Microbiome,  11. 2023.
Wolbachia is a widespread bacterial endosymbiont that can inhibit vector competency when stably transinfected into the mosquito, Aedes aegypti, a primary vector of the dengue virus (DENV) and other arboviruses. Although a complete mechanistic understanding of pathogen blocking is ...

Meiotic drive, postzygotic isolation, and the Snowball Effect

Tags: , ,
Robert L. Unckless,  bioRxiv,  2023.
As populations diverge, they accumulate incompatibilities which reduce gene flow and facilitate the formation of new species. Simple models suggest that the genes that cause Dobzhansky-Muller incompatibilities should accumulate at least as fast as the square of the number of ...

Transformative Novel Technologies and Global Environmental Governance

Tags: , , , ,
F. Rabitz,  Cambridge University Press,  2023.
Transformative Novel Technologies are potential gamechangers for confronting climate change, biodiversity loss, and many other elements of the global environmental crisis, allowing us to achieve a more sustainable future. The contemporary and future international governance of ...

The suppression of a selfish genetic element increases a male’s mating success in a fly

Tags: ,
Sophie Lyth, Andrea J. Betancourt, Tom A. R. Price, Rudi L. Verspoor,  Ecology and Evolution,  2023.
X chromosome meiotic drive (XCMD) kills Y-bearing sperm during spermatogenesis, leading to the biased transmission of the selfish X chromosome. Despite this strong transmission, some natural XCMD systems remain at low and stable frequencies, rather than rapidly spreading through ...

Gene Drive Mosquitoes from Islamic Perspective: A Preliminary Discussion

Tags: , ,
N. M. Isa,  Global Journal Al-Thaqafah,  13. 2023.
Gene drive mosquitoes could spread desired trait, such as female infertility within a wild population at a rate higher than the normal inheritance rate and could eventually wipe out the population. Consequently, this makes gene drive mosquitoes one of the promising approaches in ...

C. M. Hannah, J. H. Kennedy, M. Megan, E. Z. Gabriel, W. Michael and Z. Andrew,  bioRxiv,  2023.11.07.566100. 2023.
CRISPR/Cas9 gene drive systems are possible in a few insects and ever expanding. Nonetheless, success in one species and techniques developed for it are not necessarily applicable to other species. As such, the development and expansion of gene drive systems is dependent upon ...
