Figure Lengend Snippet: Figure 3. Effects of different aTc concentrations for CRISPRi activation on gene expression, as determined by RT‒qPCR at 0 and 24 h. (a-c) Fold changes in the dCas9 gene. (d-e) Fold changes in the number of positive sgRNAs and mmpL3 gene expression. (f-g) Fold changes in the inhA gene. Statistical significance was determined using nonparametric ANOVA (Kruskal‒Wallis test) to compare Msm inactivated and activated by 50, 100 or 200 ng/ml of aTc at each time point with the vector control, positive sgRNA, or sgRNA2. Error bars represent the standard deviation from the mean of triplicate experiments (*p < 0.05, **p ≤ 0.01, ***p ≤ 0.001).
