2-Locus Cleave and Rescue; selfish elements harness a recombination rate-dependent generational clock for self limiting gene driveG. Oberhofer, T. Ivy and B. A. Hay, bioRxiv, 2020.
Self-limiting gene drive allows control over the spread and fate of linked traits. Cleave and Rescue (ClvR) elements create self-sustaining drive and comprise a DNA sequence-modifying enzyme (Cas9-gRNAs, Cleaver) that disrupts an essential gene, and a tightly linked, uncleavable ... |

Maternal effect killing by a supergene controlling ant social organizationA. Avril, J. Purcell, S. Béniguel and M. Chapuisat, Proceedings of the National Academy of Sciences, 2020.
Supergenes are clusters of linked loci producing complex alternative phenotypes. In a series of experiments, we demonstrate that a supergene controlling ant social organization distorts Mendel’s laws to enhance its transmission to adult offspring. One supergene haplotype is ... |

Artificial Selection Finds New Hypotheses for the Mechanism of Wolbachia-Mediated Dengue Blocking in MosquitoesS. A. Ford, I. Albert, S. L. Allen, S. F. Chenoweth, M. Jones, C. Koh, A. Sebastian, L. T. Sigle and E. A. McGraw, Frontiers in Microbiology, 11:1456. 2020.
We recently used experimental evolution to reveal that Wolbachia-mediated dengue blocking could be selected upon in the A. aegypti host and showed evidence that strong levels of blocking could be maintained by natural selection. In this study, we investigate the genetic variation ... |

Small-Molecule Control of Super-Mendelian Inheritance in Gene DrivesV. López Del Amo, B. S. Leger, K. J. Cox, S. Gill, A. L. Bishop, G. D. Scanlon, J. A. Walker, V. M. Gantz and A. Choudhary, Cell Reports, 31:107841. 2020.
Summary Synthetic CRISPR-based gene-drive systems have tremendous potential in public health and agriculture, such as for fighting vector-borne diseases or suppressing crop pest populations. These elements can rapidly spread in a population by breaching the inheritance limit of ... |

Invasion and maintenance of spore killers in populations of ascomycete fungiI. Martinossi-Allibert, C. Veller, S. L. Ament-Velásquez, A. A. Vogan, C. Rueffler and H. Johannesson, bioRxiv, 2020.04.06.026989. 2020.
We show how ploidy level, rate of selfing, and efficiency of spore killing affect the invasion probability of a driving allele and the conditions for its stable coexistence with the non-driving allele. Our model can be adapted to different fungal life-cycles, and is applied here ... |

Role of gene drives in malaria elimination strategy: modeling impact and cost-effectiveness in the Democratic Republic of the CongoN. Metchanun, C. Borgemeister, J. von Braun, M. Nikolov, P. Selvaraj and J. Gerardin, medRxiv, 2020.
The tremendous burden of malaria has led to renewed efforts on malaria elimination and the development of novel tools for application where existing tools fall short. Gene drive mosquitoes, where transgenes and their associated phenotypes are efficiently propagated to future ... |

Can natural gene drives be part of future fungal pathogen control strategies in plants?D. M. Gardiner, A. Rusu, L. Barrett, G. C. Hunter and K. Kazan, New Phtologist, 2020.
Globally, fungal pathogens cause enormous crop losses and current control practices are not always effective, economical or environmentally sustainable. Tools enabling genetic management of wild pathogen populations could potentially solve many problems associated with plant ... |

Translating gene drive science to promote linguistic diversity in community and stakeholder engagementC. Cheung, S. Gamez, R. Carballar-Lejarazú, V. Ferman, V. N. Vásquez, G. Terradas, J. Ishikawa, C. E. Schairer, E. Bier, J. M. Marshall, A. A. James, O. S. Akbari and C. S. Bloss, Global Public Health, 2020.
Information about genetic engineering (GE) for vector control in the United States is disseminated primarily in English, though non-English speakers are equally, and in some geographic regions even more affected by such technologies. Non-English-speaking publics should have equal ... |

Development of zygotic and germline gene drives in miceC. Pfitzner, J. N. Hughes, M. A. White, M. Scherer, S. G. Piltz and P. Q. Thomas, bioRxiv, 2020.
Here we investigated the efficiency of CRISPR/Cas9-based gene drives in Mus musculus by constructing "split drive" systems with Cas9 under the control of zygotic (CAG) or germline (Vasa) promoters. |

Analysis of a Strong Suppressor of Segregation Distorter inDrosophila melanogasterR. G. Temin, Genetics, 215:1085-1105. 2020.
These studies highlight the polygenic nature of distortion and its dependence on a constellation of positive and negative modifiers, provide insight into the stability of Mendelian transmission in natural populations even when a drive system arises, and pave the way for molecular ... |

Genetic breakdown of a Tet-off conditional lethality system for insect population controlY. Zhao, M. F. Schetelig and A. M. Handler, Nature Communications, 11:3095. 2020.
Genetically modified conditional lethal strains have been created to improve the control of insect pest populations damaging to human health and agriculture. However, understanding the potential for the genetic breakdown of lethality systems by rare spontaneous mutations, or ... |
