Figure 2.—

Enhanced expression of TFL1 in the cry1 cry2 mutant. (A) Seedlings were grown under SD, under SD followed by LD, or under LD and harvested 16 hr after the beginning of the last photoperiod, when they had nine leaves. Data are means and SE of two biological replicates. Factorial ANOVA indicates significant photoperiod by cry1 cry2 interaction (P < 0.005). ***P < 0.001 between CRY1 CRY2 and cry1 cry2 in a Bonferroni post test. NS, not significant. (B) Daily time course of TFL1 expression in seedlings of the WT and of the cry1 cry2 double mutant grown under SD. Data are means and SE of two biological replicates (data standardized to the maximum of each experiment). The slope of the relationship between expression and time is significantly affected by the cry1 cry2 mutation (P < 0.05).
