CRISPR to go – a guide to gene editing Tephritid flies at remote facilities

Sim et al. (2018) recently published a paper in Insect Molecular Biology describing CRISPR/Cas 9 methods for gene editing in three genera of Tephritid fruit flies: Anastrepha, Bactrocera, and Ceratitis. CRISPR/Cas9 allows for targeted gene editing through homology driven repair […]

Improved HDR-Mediated Genome Editing

Jose Arturo Gutierrez-Triana and colleagues from Heidelberg University report in eLIFE a CRISPR/Cas9 based methodology that simultaneously decreases donor DNA multimerization and increases HDR single-copy integration. A common obstacle that CRISPR/Cas HDR mediated genome editing faces is the accurate and […]

Cas9 Gene Drive, Sex-Conversion and Evolved Resistance

In a recent manuscript, KaramiNejadRanjbar et al. demonstrate the development of a proof of principle Cas9-based suppression gene drive in D. melanogaster that can be applied to pest insects, and discuss the implications of resistance allele formation for practical use […]
