Fig. 8. LNG1 and LNG2 regulate longitudinal cell expansion independently of ROT3. (A) RT-PCR expression analysis of ROT3, CYP90D1, AN and ATHB13 in wild-type, lng1-1D and lng1-3 lng2-1 plants. (B) Expression analysis of LNG1 and LNG2 in wild-type and rot3-1 plants. (C) Length of the leaf blade. (D) Length of the leaf petiole. (E) Width of the leaf blade. Analyses were performed on the fifth leaves of 39-day-old plants. Measurement of cell numbers (F) and cell sizes (G) of the fifth leaves during different developmental stages. Paradermal images of palisade cells were used for measurements.
