Viral vectors hold enormous potential for genome editing in plants as transient delivery vehicles of CRISPR-Cas components. Here, we describe a protocol to assemble plant viral vectors for single-guide RNA (sgRNA) delivery. The obtained viral constructs are based on compact T-DNA binary vectors of the pLX series and are delivered into Cas9-expressing plants through agroinoculation. This approach allows rapidly assessing sgRNA design for plant genome targeting, as well as the recovery of progeny with heritable mutations at targeted loci. For complete details on the use and execution of this protocol, please refer to Uranga et al. (2021)1 and Aragonés et al. (2022).2.
