Export of ¹⁴C to the root and rosette leaves. Leaf 8 of Col-0 plants was labelled for 5 min at 6 h into the light period with ¹⁴CO₂, followed by chase periods of 0, 15, 30, 60, 180 or 360 min. At each time point, the labelled leaf, the unlabelled (sink) leaves and the root were harvested separately, and the incorporation of ¹⁴C was determined. The sum of the label in the labelled leaf, the sink leaves and the root is set to 100%. Mean ± SE (n = 5).
