Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated (Cas)9 has become an essential tool in every molecular plant breeding laboratory. CRISPR-Cas9 causes highly precise knock-out mutations in plants that can be exploited in crop improvement programmes.

This protocol describes a detailed procedure for genome editing with CRISPR-Cas9 in recalcitrant rice genotypes that otherwise show a poor response to tissue culture. With this method, high transformation efficiency can be achieved in relatively a short period.

摘要

Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated (Cas)9 has become an essential tool in every molecular plant breeding laboratory. CRISPR-Cas9 causes highly precise knock-out mutations in plants that can be exploited in crop improvement programmes. However, poor response to Agrobacterium-mediated genetic transformation in recalcitrant rice genotypes is a major limiting factor. This protocol describes a detailed procedure for genome editing with CRISPR-Cas9 in recalcitrant rice genotypes that otherwise show a poor response to tissue culture. With this method, high transformation efficiency can be achieved in relatively a short period.
