Table III. Total amount of each head group class in rosettes of wild-type (Col-0), acbp1 mutant, and ACBP1-complemented (com) plants grown at 23°C or CA followed by freezing treatment.
The values are means ± sd (nmol mg−1 dry weight; n = 3). Significant differences (P < 0.05) from the wild type in the same experiment are indicated in boldface. DGDG, Digalactosyldiacylglycerol.
