title: Changes in adenine-nucleotide content in the apical bud of Sinapis alba L. during floral transition.
abstract: The total adenylate pool of the apical buds of vegetative plants of Sinapis alba L. continuously grown in short days fluctuates over a 24-h cycle with the minimum occurring at the end of the dark period. In the buds of plants induced to flower by a single long-day treatment, total adenylate pool increases above the control level 16 h after the start of the long day, resulting mainly from a rise in ATP and ADP contents. This occurs 6 h after the increase in the soluble carbohydrate content previously shown to occur in the apical buds of plants induced to flower (Bodson 1977, Planta 135, 19-23). A transient rise of the energy charge occurs 22 h after the start of the inductive long day.
