In vitro enzymatic assays of crude leaf protein extracts of olives Agroinoculated with either pTRV2-EV or pTRV2-OeGLU constructs. (A) Relative enzymatic activity against oleuropein at 6 min. (B) Relative enzymatic activity against oleuropein at regular time intervals. (C) Relative enzymatic activity against pNPGlu. Three technical replicates of three biological replicates per treatment were analyzed. Mean ± SE and asterisks denote statistical significance (***P ≤ 0.001, **P ≤ 0.01, *P ≤ 0.05, ns: not significant; Student’s t-test). EV, empty vector; OeGLU, oleuropein β-glucosidase; pNPGlu, p-nitrophenyl β-D-glucopyranoside.
