Mutations in prr9/prr7 delay the elf3 flowering phenotype under LD and SD photoperiods. Flowering time in the WT (Col-0), elf3, prr, and elf3/prr mutants under LDs a, b) or SDs c, d). Flowering was measured under each photoperiod by the number of rosette leaves a, c) or the days taken to produce a bolt that was ∼1 cm above the rosette b, d). For both photoperiods, plants were grown under a constant temperature of 22°C. Experiments were repeated twice, with a minimum of 8 plants analyzed for each experimental repeat. Letters signify a significant difference of P < 0.05 as determined by ANOVA with a Tukey HSD post hoc test.
