Abstract

Abstract We report that Cas9/gRNA mediates efficient genetic modifications in Drosophila. Through targeting seven loci, we achieved a germline efficiency of up to 100%. Genes in both heterochromatin and euchromatin can be modified efficiently. Thus the Cas9/gRNA system is an attractive tool for rapid disruption of essentially any gene in Drosophila.
