A tobacco calmodulin-like protein， rgs-CaM， has been shown to interact with viruses in a variety of ways; it contributes to geminivirus infections but is also involved in primed immunity to the cucumber mosaic virus. Sequence similarity searches revealed several calmodulin-like proteins similar to rgs-CaM (rCML) in Arabidopsis and other Solanaceae plants， including potato (Solanum tuberosum). To analyze the functions of each rCML， mutations were introduced into potato rCMLs using the CRISPR/Cas9 system. Here， we describe our protocol of the CRISPR/Cas9-mediated targeted mutagenesis in stably transformed potato plants.
