Effects of continuous light on Arabidopsis flowering time. (A) A model depicting functions of photoreceptors regulating floral initiation in Arabidopsis grown in continuous lights. The arrows represent a stimulatory effect, and the lines terminated with a bar represent an inhibitory effect on flowering. (B) Thirty-six-day-old plants of the indicated genotypes grown under continuous cool white-plus-FR light (CW+FR; ≈93 μmol·s−1·m−2 with an R:B:FR ratio of ≈2.8:1.1:1.0). (C) Flowering time of the genotypes indicated grown on soil under CW+FR as described in B. The means of three independent experiments with individual samples containing 20–50 plants and the corresponding standard errors are shown.
