Carbohydrate contents of the apices of flowering stems and of leaves of mutant and wild-type plants. Values are means of measurements on five samples per time point, and se is indicated. Black bars, the wild type; white bars, the gsl7 mutant. A, Starch and sugars in apices of flowering stems. Plants were grown for 46 d in 12 h of light and 12 h of dark. Samples were harvested at the end of the night and 3 and 6 h into the light period. Each sample consisted of two flower heads (approximately the apical 1 cm of the main stem, consisting of the terminal cluster of flowers and buds). B, Starch in leaves. Plants were grown for either 35 or 42 d. Each sample was harvested at the end of the night and consisted of three fully expanded leaves from a single plant.
