2. Figure 1
Model of systemic regulation of apical dominance by auxin and sucrose.
The growing shoot tip of the intact plant (left) inhibits axillary bud outgrowth through maintaining a strong sink strength for sugars (blue dashed arrows) and by producing auxin (red dashed arrow). After decapitation (right), sucrose distribution is rapidly modified and auxin in the stem is progressively depleted. This process triggers bud release and growth into branches (white arrows). The plants pictured are 23-day-old garden pea (Pisum sativum cv Torsdag) plants grown under 18 hour photoperiod. Decapitated plants had the shoot tip removed above the highest expanded leaf 11 days prior to the photograph being taken. We would like to thank Thien Long Tran for providing the plants that appear in this figure.
