Genome editing

Guest Editors: Jennifer Doudna and Charles Gersbach

Advances in the development of genome engineering tools — such as zinc finger proteins, TALEs, and more recently the CRISPR/Cas9 system — are allowing us to study the genomes of diverse organisms at the functional level with unprecedented ease and accuracy.

Genome Biology highlights this young, dynamic field with a special issue covering the applications of genome editing technologies in all kingdoms of life, both wet-lab and computational methodological advances, novel insights into the biology of naturally occurring CRISPR/Cas systems, discussions on the challenges and opportunities of these new techniques, and more.

In addition to the selection of articles below, here you can also find a series of blogs and Author Q&As on Genome Biology articles and other interesting studies from the field of genome editing.
