Plants were grown at 600 μmol of photons m-2 s-1 under long day conditions (LD) for 3 weeks or under short day conditions (SD) for 6 weeks. Leaf number and rosette dry weight were measured as described in Section “Materials and Methods.” The numbers in OE-NTRC lines represents independent transgenic lines. Each value is the mean ± SE of four to five independent determinations. ND, not determined. *P, **P, ***P < 0.05, 0.01, 0.001 (student’s t-test), respectively, compared with WT plants. For the other abbreviations, see the legend of Figure 3.
