Fig. 5 in Induction of promising antibacterial prenylated isoflavonoids from different subclasses by sequential elicitation of soybean

Fig. 5. Content (μmol/g DW) of prenylated isoflavonoids in (H2O2 + AgNO3)- elicited (and subsequently B. subtilis (B)- or Rhizopus spp. (R)- elicited) soybean seedlings in comparison to the recently proposed priming and elicitation treatment, ROS + R published by Kalli et al., 2020. Prenylated isoflavonoids were classified into (from right to left): C4-glyceollins (light grey), C2-glyceollins (light grey striped), prenylated isoflavones (grey), and phaseol (dark grey). Treatments are shown at their optimum day (4d for (H2O2 + AgNO3)-elicited and 3d for the sequentially elicited or ROS + R treatments) after "late" application with respect to maximum prenylated isoflavonoid accumulation. Error bars indicate the standard deviation of three biological replicates. Asterisks signify a statistically higher accumulation of a specific prenylated isoflavonoid subclass compared to the rest of the treatments (p <0.05).
