A, Seedling establishment in high (160 μmol m−2 s−1) and low (10 μmol m−2 s−1) photon flux densities. Black box, untransformed wild-type Col0; gray box, line 64; narrow hatched box, line 122; medium hatched box, line 192; wide hatched box, line 195; white box, line 16. Suc was not included in the medium; values are the mean ± se of measurements on three separate batches of 30 seedlings. B, Hypocotyl length of 35S-PCK1 antisense and wild-type etiolated seedlings. Seedlings were grown in the dark on medium without Suc for 5 d. Values are the mean ± se of measurements on three separate batches of 30 seedlings.
