RD20 is involved in the floral transition. A, Peroxygenase activity was required for RD20 effects on flowering. Lines overexpressing enzymatically active (right) or inactive (left) RD20 were grown under short-day conditions for 4 weeks, when the photograph was taken. B, Modifications of RD20 expression or RD20 activity affect the floral transition of the mutant lines. Flowering changes were determined by measuring the bolting times (top), the number of rosette leaves at the bolting time of RD20-overexpressing lines (middle), and the length of the stems of 5-week-old plants (bottom). All lines were grown side by side under short-day conditions (SD). Data are means of two different biological samples (n = 35 per experiment per genotype). C, The RD20 accelerating effect on the floral transition is dependent on the photoperiod. Compared with controls, when grown under long-day conditions (LD), the bolting time is reduced in lines overexpressing RD20 (n = 28). The experiment was repeated twice. In all parts, differences between transgenic lines versus their respective controls were significant as indicated: **P < 0.01, *P < 0.05.
