Flowchart and functional validation of the software-assisted procedure for gRNAs cloning with GoldenBraid. (A) Schematic representation of the software tools for Cas9 gRNAs cloning. Single Cas9 gRNAs cloning is assisted via the Single Cas9_gRNA Domesticator (tS9D) and the Single Cas9_gRNA Assembler (tS9A) (top). Cas9 multiplexing gRNAs are assembled with the use of three consecutive software tools: the Multi Cas9_gRNA Domesticator 1 (tM9D1), the Multi Cas9 gRNA Domesticator 2 (tM9D2), and the Multiple Cas9_gRNA Assembler (tM9A) that creates Level 1 gRNA arrays (middle). The CRISPR for Dummies tool takes 1–6 protospacers as input and generates Level 1 gRNA arrays in a single step (bottom). (B) Correlation of Cas9 gRNAs predicted on-target scores and editing efficiencies tested in N. benthamiana transient expression. Schematic representation of the plasmids co-infiltrated in this experiment (top) and Cas9 guide RNAs editing efficiencies (left axis, bars, determined with ICE) and their corresponding on-target score (right axis, line) determined with the “Rule Set2 scoring” (bottom). (C) Correlation of Cas12a crRNAs predicted on-target scores and editing efficiencies tested in N. benthamiana transient expression. Schematic representation of the plasmids co-infiltrated in this experiment (top) and Cas12a guide RNAs editing efficiencies (left axis, bars, determined with TIDE) and their corresponding on-target score (right axis, line) determined with CINDEL (bottom).
