Chemical and Light Inducible Recombinases

In a recent Nature Communications publication Weinberg et al., (2019) report developing and testing a repertoire of inducible site-specific recombinases capable of being activated by different inducers such as small molecules, light, and temperature.   While developed and tested in mammalian cells and transgenic mice, they will be widely useful in insect systems.

One-step recombination-mediated cassette exchange (RMCE) in Drosophila suzukii

Schetelig et al. (2018) describe a relatively efficient recombinase-mediated cassette exchange (RMCE) system for engineering the recently sequenced genome (Chiu et al., 2013) of the spotted wing drosophila, Drosophila suzukii, which is a significant pest of small and stone fruits. […]

Cre/lox-Recombinase-Mediated Cassette Exchange in Aedes aegypti

Häcker et al 2017 reports the use of Cre/lox Recombination-Mediated Cassette Exchange (RMCE) in Aedes aegypti providing a pathway for interrogating specific genomic locations for the use of transgenic constructs in future genetic control methods. Häcker et al 2017 first generated […]

Anopheles gambiae Transgenesis Tool Box – Major Additions

Volohonsky et. al. (2015) in a just-published paper in G3 entitled  “Tools for Anopheles gambiae transgenesis”  describe a wealth of new tools for creating transgenic An. gambiae. There has been a protocol for Anopheles gambiae transgenesis for over 15 years, […]

A Stable, Replaceable, Highly Efficient Transgene Expression System

Long et. al. in Scientific Reports describe a system for creating stable sites in the genome of Bombyx mori that allow for site-specific recombination-mediated integration of transgenes. Transposons are essential platforms for many insect genetic technologies and are typically used […]
