Cas9 Orthologs with Minimal PAM Requirements

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, […]

Precision-Guided Sterile Insect Technique

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 […]

A Multiple Gene Drive System

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 […]

2019 IGTRCN Technical Short Course – Applications Open

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) […]

Whole-brain, Single Cell Activity Mapping in Transgenic Gryllus

Watanabe et al in eNeuro (2018) report their successful development of transgenic cricket Gryllus bimaculatus that bears a transcriptional reporter for whole-brain, single cell-resolution activity mapping. In order to construct a transcriptional reporter for activity mapping, it is critical to […]

HyperActive piggyBac Transposase for Transgenesis

Eckermann et al. (2018) recently published a report in Insect Biochemistry and Molecular Biology demonstrating the efficacy of hyperactive piggyBac transposase for creating transgenic insects, which may be of interest to researchers looking to initiate transgenic projects in ‘non-model’ insect […]

Driving into doublesex

Kyrou et al. (2018) in a recent paper in Nature Biotechnology report identifying a highly conserved target site in the Anopheles gambiae fertility gene doublesex (dsx), that cannot tolerate mutations. They built a gene drive targeting this site in dsx […]
