The establishment of reliable and efficient systems for genome editing in Phytophthora is very important for studying gene functions. Here, step-by-step methods for CRISPR/Cas9-based gene knockout and in situ complementation for Phytophthora sojae are presented. These steps include the sgRNA design, Cas9-sgRNA plasmid construction, homologous replacement, complementation vector construction, P. sojae transformation, and detection of mutations for both gene knockout and in situ complementation. These methods may also potentially be adapted for other Phytophthora species.
建立可靠且高效的疫霉菌基因组编辑系统对于研究基因功能非常重要。本文介绍了基于CRISPR/Cas9的大豆疫霉菌基因敲除和原位互补的逐步方法。这些步骤包括sgRNA设计、Cas9-sgRNA质粒构建、同源替换、互补载体构建、大豆疫霉菌转化以及基因敲除和原位互补的突变检测。这些方法也可能适用于其他疫霉菌物种。
