Precise and Efficient Nucleotide Substitution Via Noncanonical Homology-directed Repair.

In a recent paper in Genome Research Nakajima et al. 2018 propose an efficient gene editing strategy by nucleotide substitution that overcomes three general problems associated with current methods. First, indels caused by the traditional Cas9-induced Double Strand Breaks (DSB), […]

A Protocol for the Highly Efficient Generation of Stable Mosquito Knockout Lines Using CRISPR/Cas9

In their recent paper in G3: Genes|Genomes|Genetics, Li et al. describe a highly efficient protocol for the generation of stable knockout lines using CRISPR/Cas9. The ability of effectively targeting and disrupting gene function is essential for gene functional analysis studies […]

Phosphorothioate oligomers increase knock-in frequency and precision in TALEN- and Cas9-mediated genome editing

In a recent paper by Renaud et al. (2016), the authors investigate methods to increase genome editing knock-in efficiency by modifying the chemistry of the donor oligomers to be resistant to nuclease activity. The modifications they tested included locked nucleic […]

CRISPR/Cas9 Gene Editing in Papilionid Butterflies

Li et al (2015) recently published an exciting paper on butterflies genomics and functional genomics . Li et al have worked towards producing high quality genomes for extremely heterozygous and closely related butterflies P. xuthus and P. machaon. Further, they […]

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 […]

BuD: Another Tunable DNA-Binding Domain for Genome Modification

Tunable DNA-binding domains with high specificity remain important tools for constructing genome modifications even with the current popularity of the CRISPR/Cas9 system. Stella at al (2014) describe their analysis of a DNA-binding protein, BurrH, from the symbiotic bacterium Burkholderia rhizoxinica […]

Delivering Reprogramed Meganucleases With Lentiviruses- Is this Applicable to “Difficult” Insects?

Delivering biologically relevant nucleic acids and proteins to appropriate cells of multicellular organisms for the purposes of genetically modifying either somatic or germline genomes is a central problem for not only insect biologists but for those working on other organisms […]

Genetically Modified Annelids: Platynerieis dumerilii. Not Unlike Modifying Insects

The bristle worm, Platynerieis dumerilii, is a marine annelid with a biology that makes it of interest because of the development of its nervous system, reproductive cycles that are synchronized with lunar phases and its neuroendocrinology among other things. Even […]

Development, Growth & Differentiation Devote Issue to Genome Editing

Genome editing with engineered nucleases is an emerging technology that enables manipulation of targeted genes in many organisms and cell lines. Development, Growth & Differentiation has devoted an entire issue to genome editing.  The paper describing the successful use of […]
