High light systemic acquired acclimation-array, spectral output of specific LEDs and schematic overview of experiments conducted throughout the research article. (A) HL LED-array. Inset depicts a close-up image of a single treated Arabidopsis plant. Components of the HL LED-array include (i) power supply, (ii) current limiters for each LED, (iii) individual movable LED stage with heat sink, and (iv) light focusing lens. (B) Measured irradiance spectra from colored LEDs, n = 3. (C) Schematic diagram of the main areas of study, light treatments, and methods of analysis conducted throughout the research article. For all light treatment mature plants of approximately 4 weeks old grown under normal light conditions as detailed in Section “Materials and Methods” are used. For more detail on each individual treatment and analysis refer to Section “Materials and Methods.” *Experiment conducted irrespective of leaf position. **Experiment conducted taking leaf position in to account.
