Abstract |
Gene editing using clustered, regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) nuclease is an excellent tool for assessing gene function in plants. However, delivery of CRISPR/Cas-editing components into plant cells is still a major bottleneck and requires tissue culture-based approaches and regeneration of plants. To overcome this limitation, several plant viral vectors have recently been engineered to deliver single-guide RNA (sgRNA) targets into SpCas9-expressing plants. Here, we describe an optimized, step-by-step protocol based on the tobacco rattle virus (TRV)-based vector system to deliver sgRNAs fused to mobile tRNA sequences for efficient heritable editing in Nicotiana benthamiana and Arabidopsis thaliana model systems. The protocol described here could be adopted to study the function of any gene of interest. |
