Chapter synopsis: This chapter reviews the principles of CRISPR cloning in binary vectors and the different methods and elements employed, including the nucleases alternative to Cas9. It pays special attention to modular cloning strategies and multiplexing tools as well as the engineering of expanded Cas activities. Finally, the chapter includes a case study of the cloning of a nine gRNA multiplex construct and the analysis of its transformants in tobacco plants.
