Biolistic Delivery of CRISPR/Cas9 with Ribonucleoprotein Complex in Wheat

Methods Mol Biol. 2019:1917:327-335. doi: 10.1007/978-1-4939-8991-1_24.

Abstract

The great advances in exploiting the CRISPR/Cas9 system are paving the way for targeted genome engineering in plants. Genome editing by direct delivery of CRISPR/Cas9 ribonucleoprotein complexes (RNPs) into plant cells reduces off-target mutations and avoids the integration of foreign DNA fragments, thus providing an efficient and accurate method for precision crop breeding. Here we describe an RNP-based genome editing protocol for wheat. The protocol covers the in vitro transcription of sgRNA, purification of Cas9 protein, biolistic delivery of CRISPR/Cas9 RNPs, and tissue culture procedures for regenerating testable seedlings.

Keywords: Biolistic delivery; CRISPR/Cas9; Ribonucleoprotein; Wheat.
