Rapid and user-friendly open-source CRISPR/Cas9 system for single- or multi-site editing of tomato genome

摘要

without several procedures, such as PCR and plasmid extraction. The two binary vectors are designed according to the principles of standard BioBrick assembly to be used as an open-source tool. For example, we used BioBrick as a visual T-DNA tag. We also developed a primer design aid to complement the system. With this primer design aid, researchers can rapidly obtain primers and GC content, and sgRNA sequence of target site. Our CRISPR/Cas9 system can perform single- and multi-site editing and multiple gene editing to produce various types of mutations in tomato. This rapid and user-friendly CRISPR/Cas9 system for tomato can be potentially used for mutagenesis of important crop species for genetic improvement and is suitable for research into the function of genes.
