Figure 2. Dimensions of leaf blades and petioles of prr9;prr7;prr5 mutants under red or blue light. Plants were grown under continuous white light (60 μmol m^-2 s^-1 PPFD) for 16 d.a.g as control groups, or for 10 d.a.g under continuous white light and 6 d under continuous red or blue light (60 μmol m^-2 s^-1 PFD). 1st and 2nd leaves were measured at 17 d.a.g. (A) The Images of the leaves of WT and prr9;prr7;prr5 (d975) mutants under every light conditions. A scale bar indicates 5 mm. (B) and (C) In each line, each organ size was normalized to the average size of the control group. Error bars represent SE, and asterisks indicate significant difference from WT using Student's t-test (n ≥ 6, p ≤ 0.05).
