The effect of AeaAST-C (10−9 M) on JH biosynthesis was evaluated on Br-CA-CC complexes incubated in culture medium M-199 alone (control) or with the addition of 200 μM of nine different precursors: ACoA (acetyl-CoA), MVA (mevalonic acid), MevP (mevalonic acid 5-phosphate), MevPP (mevalonic acid 5-pyrophosphate), FPP (farnesyl diphosphate), FOL (farnesol), FAL (farnesal), FA (farnesoic acid) and MF (methyl farnesoate). Each data point represents the means ± S.E.M. of 2-4 independent biological replicates of three Br-CA-CC complexes. Asterisks denote significant differences (unpaired t-test; *** P ≤ 0.001).
