    Addgene inc hammerhead hh ribozymes
    Identification of the most efficient Cas12a orthologue and method for crRNA expression. ( a ) Three target sites (T1-T3) in tomato PHYTOENE DESATURASE (SlPDS) were selected. ( b ) Mutation frequencies for three Cas12a orthologues and four methods of crRNA expression at three targets (T1-T3). Note the different y-axis scales for T1, T2, and T3. Error bars indicate standard error (n = 3). Different letters indicate significant differences ( p < 0.05) between mutation frequencies induced by the different orthologues, as determined using Two-Way ANOVA followed by Tukey’s HSD Post-Hoc test. ( c ) For LbCas12a, two additional expression methods using a PolII promoter, and a PolII promoter combined with <t>ribozymes</t> were tested. Error bars indicate standard error (n = 3). Different letters indicate significant differences ( p < 0.05) between mutation frequencies obtained using different crRNA expression methods, as determined using Two-Way ANOVA followed by Tukey’s HSD Post Hoc test.
