Fig. 10 — Endogenous background fluorescence. Variegated arabidopsis was photographed with white light (A) and with a filter cube containing a yellow barrier filter (B). The Canon EOS 30D camera setting for the fluorescent images was 5 s exposure, ISO 400 and f/8.0. The light intensity was ∼11 000 lx. ImageJ was used to measure green pixel intensity from the green regions and white regions of the variegated plants (C). Range bars are 95% confidence intervals. Wild-type Columbia-O plants were photographed with the filter cube containing a yellow barrier filter (0.03 s exposure, ISO 1600, f/2.8, intensity of ∼10 000 lx) before 95 % ethanol extraction (D) and after extraction (photography conditions the same as D) (E). Green channel pixel intensity was measured (F). Range bars are 95 % confidence intervals.
