FIGURE 4.

Impact of mycorrhization on the metabolic profile of locally infested leaves of C. aurantium plants. Non-targeted principal component analysis (PCA) obtained from a non-target analysis by UPLC-QTOFMS of locally infested leaves at (A) 24 h post infestation and (B) 48 h post infestation with T. urticae. 3 months old plants were infested with five 2-days-old female T. urticae (2 leaves per plant). 24 or 48 h after infestation, infested leaves were detached and frozen at –80°C. A pool from 6 individual plants was employed for each combination. Three independent and two technical replicates were randomly performed (n = 5). Four different treatments were analyzed: NM: non-mycorrhizal non-infested plants. AM: mycorrhizal non-infested plants. NM inf: non-mycorrhizal infested plants. AM inf: mycorrhizal infested plants.
