Fig. 6: Distinct stress-induced ROS and SA waves in living plants.
From: Decoding early stress signaling waves in living plants using nanosensor multiplexing
Time-plots of H2O2 concentration derived from nanosensor experiments (blue circles) and mathematical modeling (blue lines), as well as SA concentration derived from nanosensor experiments (red circles) and mathematical modeling (red lines), for pak choi plants that are (a) mechanically-wounded, b Xcc infected, c high light treated, and (d) high heat treated. Each type of stress treatment of the pak choi leaves occurs at approximately t = 10 min (black arrow). Shaded regions represent standard error across 3 independent replicates. Residual plots of [H2O2]model−[H2O2]experimental (blue) and [SA]model−[SA]experimental (red) are shown underneath each fit for the different plant stresses; Temporal characterization of experimental H2O2 wave (blue block) and modeled H2O2 wave (blue diagonal stripes) in terms of (e) FWHM, f H2O2 production rate, and (g) H2O2 decay rate for each individual type of plant stress; h Onset time of SA production from experimental data (red block) and mathematical modeling (red diagonal stripes) for each individual type of plant stress. Bar graphs of experimental data show the mean values with error bars representing standard error from independent experiments (n = 3). Dots represent each data points.
