Early Zn2 -induced effects on the membrane potential account for primary heavy metal susceptibility in tolerant and sensitive Arabidopsis species

Original language description

Uptake of heavy metals by plant root cells depends on electro-physiological parameters of the plasma membrane. In this study, responses of the plasma membrane in root cells were analysed where early reactions to the metal ion-induced stress are localized. Three different Arabidopsis species with diverse strategies of their adaptation to heavy metals were compared: sensitive Arabidopsis thaliana and tolerant A. halleri and A. arenosa. Plants of A. thaliana Col-0 ecotype and plants of A. arenosa and A. halleri originating from natural metallicolous populations were exposed to high concentrations of Zn-2. Plants were tested for root growth rate, cellular tolerance, plant morphology and cell death in the root apex. In addition, the membrane potential (E-M)of mature cortical root cells and changes in the pH of the liquid culture media were measured. Primary roots of A. halleri and A. arenosa plants grew significantly better at increased Zn-2 concentrations than A. thaliana plants. Elevated
