Fatty acid turnover is enhanced during extended darkness. A, Total leaf fatty acid content at the end of the light period. B, Total leaf fatty acid content after dark treatment (D) for 8 and 24 h. C, Total leaf fatty acid loss between 8 and 24 h of darkness. Data represent mean ± se for three independent samplings of 3-week-old wild-type (WT) and mutant plants. Asterisks indicate statistically significant differences from the dark-treated wild type (B) or the wild type (C) based on Student’s t test (P < 0.05).
