Regulating the expression of gene drives is key to increasing their invasive potential and the mitigation of resistance (2021)
Journal Article
Hammond, A., Karlsson, X., Morianou, I., Kyrou, K., Beaghton, A., Gribble, M., …Nolan, T. (2021). Regulating the expression of gene drives is key to increasing their invasive potential and the mitigation of resistance. PLoS Genetics, e1009321 - ?. https://doi.org/10.1371/journal.pgen.1009321

Homing-based gene drives use a germline source of nuclease to copy themselves at specific target sites in a genome and bias their inheritance. Such gene drives can be designed to spread and deliberately suppress populations of malaria mosquitoes by i...
