Figure Lengend Snippet: Effect of the reflected low R:FR treatments on carotenoid content. Arabidopsis plants were exposed to the biological and artificial low R:FR light for 12 hours a day for seven days or kept under control (weed-free) condition prior to sampling. Black bars represent the control while light grey and dark grey bars represent the biological and artificial low R:FR treatments, respectively. Decreases in total carotenoid content in the biological and artificial low R:FR treatments (A) and no changes in the levels of lutein (B) , β-carotene (C) , violaxanthin, (D) , and neoxanthin (E) in the biological low R:FR treatment. The levels of lutein, β-carotene, and violaxanthin in the artificial low R:FR treatment are lower than that in the control.Total carotenoid data represent means ± SEM for four replicates consisting of three plants per treatment while individual carotenoid data represent means ± SEM for three independent experiments each consisting of three plants per treatment. Means were separated using Tukey’s HSD test ( P <0.05). Letters indicate statistical significance of differences across treatments.

Article Snippet: For these HPLC standards, lutein was obtained from Cayman Chemicals (Ann Arbor, MI, USA). β-carotene, violaxanthin, and neoxanthin were obtained from Sigma Aldrich (Oakville, ON, Canada).
