The Potential for a Released Autosomal X-Shredder Becoming a Driving-Y Chromosome and Invasively Suppressing Wild Populations of Malaria MosquitoesY. Alcalay, S. Fuchs, R. Galizi, F. Bernardini, R. E. Haghighat-Khah, D. B. Rusch, J. R. Adrion, M. W. Hahn, P. Tortosa, R. Rotenberry and P. A. Papathanos, Frontiers in Bioengineering and Biotechnology, 9. 2021.
Sex-ratio distorters based on X-chromosome shredding are more efficient than sterile male releases for population suppression. X-shredding is a form of sex distortion that skews spermatogenesis of XY males towards the preferential transmission of Y-bearing gametes, resulting in a ... |

Patterns and mechanisms of sex ratio distortion in the Collaborative Cross mouse mapping populationB. A. Haines, F. Barradale and B. L. Dumont, Genetics, 219:iyab136. 2021.
In species with single-locus, chromosome-based mechanisms of sex determination, the laws of segregation predict an equal ratio of females to males at birth. Here, we show that departures from this Mendelian expectation are commonplace in the 8-way recombinant inbred Collaborative ... |

Patterns and Mechanisms of Sex Ratio Distortion in the Collaborative Cross Mouse Mapping PopulationB. A. Haines, F. Barradale and B. L. Dumont, bioRxiv, 2021.
In species with single-locus chromosome-based mechanisms of sex determination, the laws of segregation predict an equal ratio of females to males at birth. Here, we show that departures from this Mendelian expectation are commonplace in the 8-way recombinant inbred Collaborative ... |

Converting female mosquitoes to non-biting males with implications for mosquito controlM. V. Candy, Vet Candy, 2020.
Virginia Tech researchers have proven that a single gene can convert female Aedes aegypti mosquitoes into fertile male mosquitoes and identified a gene needed for male mosquito flight. Male mosquitoes do not bite and are unable to transmit pathogens to humans. Female mosquitoes, ... |

Cellular mechanisms regulating synthetic sex ratio distortion in the Anopheles gambiae germlineR. E. Haghighat-Khah, A. Sharma, M. R. Wunderlich, G. Morselli, L. A. Marston, C. Bamikole, A. Hall, N. Kranjc, C. Taxiarchi, I. Sharakhov and R. Galizi, Pathogens and Global Health, 114:370-378. 2020.
Meiotic cleavage of rDNA repeats, located in the sex chromosomes of A. gambiae SD males, affects the competitiveness of mature sperm to fertilize the female oocyte. |

Assessing the acoustic behaviour of Anopheles gambiae (s.l.) dsxF mutants: implications for vector controlM. P. Su, M. Georgiades, J. Bagi, K. Kyrou, A. Crisanti and J. T. Albert, Parasites and Vectors, 13:507. 2020.
We analysed sound emissions and acoustic preference in a doublesex mutant previously used to collapse Anopheles gambiae (s.l.) cages. |

Generating single-sex litters: development of CRISPR-Cas9 genetic tools to produce all-male offspringC. Douglas, V. Maciulyte, J. Zohren, D. M. Snell, O. A. Ojarikre, P. J. Ellis and J. M. A. Turner, bioRxiv, 2020.09.07.285536. 2020.
Using the mouse as a model, we developed a synthetic, two-part bicomponent strategy for generating all-male litters. |

Tackling Dengue fever by turning female mosquitoes into malesT. Sandle, DIGTAL JOURNAL, 2020.
T. Sandle (2020). DIGTAL JOURNAL Genetic engineering appears to be the key for delivering mosquito control, according to new research. Scientists have successfully converted female mosquitoes into non-biting males. |

Malaria mosquitoes eliminated in lab by creating all male populationsH. Dunning, Imperial College London, 2020.
A team led by Imperial College London spread a genetic modification that distorts the sex ratio through a population of caged Anopheles gambiae mosquitoes using ‘gene drive’ technology. |

Genome-wide transcriptome profiling reveals genes associated with meiotic drive system of Aedes aegyptiShin, DB, K. Susanta; Severson, W. David, Insects, 10:e25. 2019.
Aedes aegypti is an important mosquito vector of several arboviruses, including dengue, yellow fever, Zika, and Chikungunya, which cause significant human morbidity and mortality globally. In certain populations of this mosquito, a native meiotic drive system causes abnormal ... |
