abstract：:Recent studies have suggested that aluminium (Al) induces programmed cell death (PCD) in plants. To investigate possible mechanisms, fluorescence techniques were used to monitor the behaviour of mitochondria in vivo, as well as the activation of caspase-3-like activity during protoplast PCD induced by Al.
