Table III. Cell wall-related genes and genes involved in lipid metabolism affected by GA level in shoots of Arabidopsis plants grown at 350 or 750 µmol CO2 mol−1

Values in boldface were determined by Student’s t test to be significantly different from the control (P < 0.05). Values are means ± se of three independent replicates.
