Abstract Cadmium (Cd) is one of the most widespread and toxic heavy metals to plants. Extracellular ATP (exATP) is
thought to be an extracellular effector in regulating the physiological responses of plant cells to environmental stresses.
However, the function of exATP in Cd-stressed plant cells is much unknown. The present work showed that treating
tobacco (Nicotiana tabacum L. cv. Bright Yellow-2) cell-suspension cultures with exogenous CdCl2 reduced the cell
viability, exATP level, and Mg content. However, the production of reactive oxygen species (ROS), Cd content, and
electrolyte leakage of the cells were enhanced by exogenous CdCl2. When the… More >
