Rapid turnover of pathogen-blocking Wolbachia and their incompatibility lociDylan Shropshire, William R. Conner, Daniel Vanderpool, Ary A. Hoffmann, Michael Turelli, Brandon S. Cooper, bioRxiv, 2023.At least half of all insect species carry maternally inherited Wolbachia alphaproteobacteria, making Wolbachia the most common endosymbionts in nature. Wolbachia spread to high frequencies is often due to cytoplasmic incompatibility (CI), a Wolbachia-induced sperm modification ... Keywords: Aedes aegypti, Burkina Faso, wAlbB, wolbachia |

Homing-based gene drives can introgress rapidly into local genetic backgrounds with minimal chromosomal conversion in Anopheles gambiaeTony Nolan, Poppy Pescod, Giulia Bevivino et al., Research Square, 2023.CRISPR-Cas9 gene drive control strategies use a homing selfish genetic element which induces a double-stranded break at the target site and is copied into the opposing chromosome, breaking an essential gene and ensuring super-Mendelian inheritance. During the copying process SNPs ... Keywords: Aedes aegypti, Burkina Faso, wAlbB, wolbachia |

Rescue by gene swamping as a gene drive deployment strategyKeith D. Harris, Gili Greenbaum, Cell Reports, 42. 2023.Gene drives are genetic constructs that can spread deleterious alleles with potential application to population suppression of harmful species. As gene drives can potentially spill over to other populations or species, control measures and fail-safe strategies must be considered. ... Keywords: Aedes aegypti, Burkina Faso, wAlbB, wolbachia |

A framework for identifying fertility gene targets for mammalian pest controlClark, A. C., Edison, R., Esvelt, K., Kamau, S., Dutoit, L., Champer, J., Champer, S. E., Messer, P. W., Alexander, A., & Gemmell, N. J., Molecular Ecology Resources, 00:1–14. 2023.Fertility-targeted gene drives have been proposed as an ethical genetic approach for managing wild populations of vertebrate pests for public health and conservation benefit. This manuscript introduces a framework to identify and evaluate target gene suitability based on ... Keywords: Aedes aegypti, Burkina Faso, wAlbB, wolbachia |
