Final yield of abietanes diterpenes in S. sclarea HRs overexpressing the three different TFs. The yield was determined as amount of individual abietane compound (mg L-1) in the final biomass obtained from 1 liter of AtWRKY18, AtWRKY40 and AtMYC2 overexpressing S. sclarea HR lines. Values are means ± SD from three biological replicates. ** and *** indicate significant differences at P ≤ 0.01 and P ≤ 0.001, respectively, between the final yield of individual abietane diterpenes in the control and overexpressing HR lines.
