Interactions between hormones in the control of lateral shoot growth. Auxin is transported from the apical meristem while cytokinin and strigolatone are transported from the roots (shown by black arrows). Red bars show repression while blue arrows show activation. Lateral buds have the potential to grow into side shoots when the hormone balance permits, and can be achieved experimentally by removing the apical meristem.
