Local light inputs modulate the spatial coordination of the clock.

(A) Period estimates for different organs under constant red and blue light or DD. ***p < 0.001, by two-tailed t test, Welch correction. (B) Times of peaks of GI::LUC expression in different organs under constant red and blue light or DD. Plots represent the 25th percentile, median, and the 75th percentile for the peak times of organs scored as rhythmic. (C) Representative phase plot of GI::LUC expression across longitudinal sections of the hypocotyl and root of a single seedling under DD. (D) Period estimates of GI::LUC for different organs under constant red light in the phyb-9 mutant. **p < 0.01, ***p < 0.001, by two-tailed t test, Welch correction. (E) Times of peaks of GI::LUC expression in different organs under constant red light in the phyb-9 mutant. Plots represent the 25th percentile, median, and the 75th percentile for the peak times of organs scored as rhythmic. (F) Representative phase plot of GI::LUC expression across longitudinal sections of the hypocotyl and root of a single seedling under constant red light in the phyb-9 mutant. For red and blue light data, N and n are as presented in Fig 2. For DD, N = 3; phyb-9 red light, N = 4. For all, n = 23–35. N represents the number of independent experiments and n the total number of seedlings. See S1 and S2 Files for exact n, test statistics, and percentage rhythmicity in each organ. Box plots indicate the median and upper and lower quartiles, and whiskers the 9th and 91st percentiles of organs scored as rhythmic. Underlying data are available from https://gitlab.com/slcu/teamJL/greenwood_etal_2019. DD, constant darkness; GI, GIGANTEA; LL, constant light; LUC, LUCIFERASE; RT, root tip; WT, wild type.
