Gene drive and resilience through renewal with next generation Cleave and Rescue selfish genetic elementsOberhofer, G., T. Ivy and B. A. Hay, bioRxiv, 2019:2019.2012.2013.876169. 2019.
Gene drive-based strategies for modifying populations face the problem that genes encoding cargo and the drive mechanism are subject to separation, mutational inactivation, and loss of efficacy. Resilience, an ability to respond to these eventualities in ways that restore ... |

A bacterial gene-drive system efficiently edits and inactivates a high copy number antibiotic resistance locusValderrama, J. A., S. S. Kulkarni, V. Nizet and E. Bier, Nature Communications, 10:5726. 2019.
Gene-drive systems in diploid organisms bias the inheritance of one allele over another. CRISPR-based gene-drive expresses a guide RNA (gRNA) into the genome at the site where the gRNA directs Cas9-mediated cleavage. In the presence of Cas9, the gRNA cassette and any linked cargo ... |

Genetic Control of MosquitoesAlphey, L., Annual Review of Entomology, 59:205-224. 2019.
Genetics can potentially provide new, species-specific, environmentally friendly methods for mosquito control. Genetic control strategies aim either to suppress target populations or to introduce a harm-reducing novel trait. Different approaches differ considerably in their ... |

We apply the structure of source-stressor-habitat-effect-impact pathway derived from the relative risk model (Landis and Wiegers 2005) and as was demonstrated to be applicable in the National Academy of Sciences, Engineering and Medicine (NASEM) 2016 report Gene Drives on the ... |

An X-linked meiotic drive allele has strong, recessive fitness costs in female Drosophila pseudoobscuraW. Larner, T. Price, L. Holman and N. Wedell, Proceedings of the Royal Society B-Biological Sciences, 286:9. 2019.
Selfish 'meiotic drive' alleles are transmitted to more than 50% of offspring, allowing them to rapidly invade populations even if they reduce the fitness of individuals carrying them. Theory predicts that drivers should either fix or go extinct, yet some drivers defy these ... |

N, Current Biology, 29:4241-4248.e5. 2019.
Dengue has enormous health impacts globally. A novel approach to decrease dengue incidence involves the introduction of Wolbachia endosymbionts that block dengue virus transmission into populations of the primary vector mosquito, Aedes aegypti. The wMel Wolbachia strain has ... |

The Competitive Mating of Irradiated Brown Marmorated Stink Bugs, Halyomorpha halys, for the Sterile Insect TechniqueD. M. Suckling, M. Cristofaro, G. Roselli, M. C. Levy, A. Cemmi, V. Mazzoni, L. D. Stringer, V. Zeni, C. Ioriatti and G. Anfora, Insects, 10. 2019.
The sterility of eggs and nymphs from gamma-irradiated male Halyomorpha halys was investigated to determine the potential for the sterile insect technique (SIT). Males irradiated at 0, 16, 24 and 32 Gy were placed with untreated virgin females, and egg sterility was determined, ... |

Effects of a male meiotic driver on male and female transcriptomes in the house mouseA. Lindholm, A. Sutter, S. Kunzel, D. Tautz and H. Rehrauer, Proceedings of the Royal Society B-Biological Sciences, 286:1-8. 2019.
Not all genetic loci follow Mendel's rules, and the evolutionary consequences of this are not yet fully known. Genomic conflict involving multiple loci is a likely outcome, as restoration of Mendelian inheritance patterns will be selected for, and sexual conflict may also arise ... |

Meiotic drive mechanisms: lessons from DrosophilaC. Courret, C.-H. Chang, K. H.-C. Wei, C. Montchamp-Moreau and A. M. Larracuente, Proceedings of the Royal Society B: Biological Sciences, 286:20191430. 2019.
Meiotic drivers are selfish genetic elements that bias their transmission into gametes, often to the detriment of the rest of the genome. The resulting intragenomic conflicts triggered by meiotic drive create evolutionary arms races and shape genome evolution. The phenomenon of ... |

Does meiotic drive alter male mate preference?S. R. Finnegan, L. Nitsche, M. Mondani, M. F. Camus, K. Fowler and A. Pomiankowski, Behavioral Ecology, 13:194-201. 2019.
Male mate preferences have been demonstrated across a range of species, including the Malaysian stalk-eyed fly, Teleopsis dalmanni. This species is subject to sex-ratio (SR), an X-linked male meiotic driver, which causes the dysfunction of Y-sperm and the production of all-female ... |

Fitness consequences of the selfish supergene Segregation DistorterH. W. S. Wong and L. Holman, Journal of Evolutionary Biology, 33:89-100. 2019.
Segregation distorters are selfish genetic elements that subvert Mendelian inheritance, often by destroying gametes that do not carry the distorter. Simple theoretical models predict that distorter alleles will either spread to fixation or stabilize at some high intermediate ... |
