Optimized CRISPR tools and site-directed transgenesis in Culex quinquefasciatus mosquitoes for gene drive development

X. Feng, V. Lopez Del Amo, E. Mameli, M. Lee, A. L. Bishop, N. Perrimon and V. M. Gantz,  bioRxiv,  2021.02.10.430702. 2021.
Here, we developed a Culex-specific Cas9/gRNA expression toolkit and used site-directed homology-based transgenesis to generate and validate a Culex quinquefasciatus Cas9-expressing line. We showed that gRNA scaffold variants improve transgenesis efficiency in both Culex and ...
