Abstract
Over the last 25 years the primary leaves of bean have emerged as the favoured system to study the cell biology of abscission. The petioles of these leaves contain two genetically determined regions known as abscission zones (AZ) where fracture can occur. The upper AZ is found just below the lamina and its weakening results in the shedding of the leaf blade. The basal zone resides at the petiole-stem junction and its activation leads to the loss of the petiole. Weakening and subsequent fracture of these zones can be induced experimentally by removing the leaf blade.
