Loss of Function Mutations – Approaches, Limitations

Technologies are democratizing insect genetics and it seems as if everyone is thinking about making ‘knockouts’.  This is a good thing but as Housden et al. nicely explain in a recent paper in Nature Reveiws Genetics explain: “although LOF (loss […]

Harmonia axyridis, 19-spot form

Sawfly and Ladybird Beetle Gene Editing

Hatakeyama et al (2015) have successfully used gene editing technology in Athalia rosae (sawfly) and Harmonia axyridis (ladybird beetle), enlarging the range of insects in which these technologies have been applied.  These results are reported in Insect Molecular Biology. Hatakeyama […]

Cas9 + sgRNA

CRISPRscan – A Tool Aiding Selection of CRISPR-Cas9 gRNAs

Just published online in Nature Methods, Moreno-Mateos et al report testing the activities of >1200 gRNAs in zebrafish embryos and used the results to create an algorithm for predicting gRNA efficacy. The advent of the CRISPR-Cas9 system has revolutionized genome […]

Pulling Recent CRISPR/Cas9 Work in Drosophila Together

Xu et al. review the recent history of using CRISPR/Cas9-based technologies in Drosophila melanogaster. Within the last two years there have been numerous publications describing the use of CRISPR/Cas9-based technologies in Drosophila melanogaster.  These last two years have been a time […]

Harmonia axyridis, 19-spot form

Enhancer Trapping in the Ladybeetle, Harmonia axyridis

Nowadays, efforts to sequence genomes are routine experiments. But once it comes down to the bioinformatics and especially to understand the vast amount of data on a functional level – we are still struggling and good old techniques to find […]

Mutagenesis, Transposons and Transgenes: State-of-the-Art

The genetic tools available for use in Drosophila melanogaster are second to none. Insect scientists working on other insect systems and who also want to acquire or develop various genetic technologies should always be keeping their eyes on technological developments […]
