Ohde et al report the first successful development and use of CRISPR/Cas9 in the basally branching insect Thermobia domestica. By co-injecting Cas9 nuclease with sgRNA targeting a T. domestica ortholog of the Drosophila melanogaster white gene (Td-w), the authors created […]

Otte et al (2018) build upon their previous work (Schulte et al. 2014) in this new publication and demonstrate a twofold improved efficiency at generating transgenic honeybees using the piggyBac transposon system. The inability to generate high transformation rates has […]
2019 IGTRCN Technical Short Course on Insect Genetic Technologies: Theory and Practice July 21 – 26, 2019 The Insect Transformation Facility Institute for Bioscience and Biotechnology Research University of Maryland College Park Applications by April 1, 2019 (24 seats available) […]
In a recent PNAS publication by Buchman et al (2019), the authors report on the establishment and validation of transgenic Aedes aegypti containing a synthetic anti-ZIKV cassette, capable of conferring complete refractoriness to the virus. Aided by piggyBac transposon-mediated insertion […]
A recent manuscript published on Genes Genomes Genetics by Reid et al (2018) reports an exciting improvement to piggyBac-based promoter-trap designed in Anopheles stephensi. The development of this new piggyBac-based promoter-trap designs provides further knowledge and exciting venues to examine […]
Two recent papers, Jefferies et al (2018) and Martin-Martin et. al (2018), describe experiments to develop and optimise a sand fly microinjection protocol. There are 2 authors to this post: Alla Madich, Simon Collier, technical constraints on this website allow […]
In their recent paper Chatterjee and colleagues (2018) describe a natural protospacer adjacent motif (PAM) plasticity of previously uncharacterized Cas9 endonuclease from Streptococcus canis (ScCas9). Chatterjee et al (2018) report ScCas9’s affinity to minimal 5’-NNG-3’ PAM sequences and describe its accurate editing capabilities, […]
Right after the 2019 New Year, Kandul et al (2019) described a novel CRISPR-based technology which they termed as “precision guided sterile insect technique (pgSIT)”. The idea of traditional SIT was planted in 1930s, which uses radiation to induce sterility […]
Yan & Finnigan, (2018) recently published a paper in Scientific Reports describing an artificial multi-locus gene drive system by using a single Cas9 and three guide RNA (gRNA) in the budding yeast Saccharomyces cerevisiae. Nuclease-based gene drives do not follow […]
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. […]
