Effects of vernalization on the Arabidopsis clock Comparison of circadian periods of vernalized and non-vernalized Arabidopsis mutant seedlings harboring all possible combinations of FRI-FLC (n = 18–26). After vernalization treatment at 2°C for 8 weeks, plants were assayed for rhythmic leaf movement for approx. 1 week in constant dim white light. vern fri-flc τ = 23.10 ± 0.21 [SEM] h, non-vern fri-flc τ = 24.01 ± 0.24 h, vern FRI-flc τ = 23.48 ± 0.19 h, non-vern FRI-flc τ = 24.21 ± 0.23 h, vern fri-FLC τ = 23.14 ± 0.25 h, non-vern fri-FLC τ = 23.95 ± 0.32 h, vern FRI-FLC τ = 23.43 ± 0.12 h, non-vern FRI-FLC τ = 24.56 ± 0.19 h.
