- •
Cistus monspeliensis stored Zn mainly in roots minimising oxidative stress.
- •
Zn content in shoots and roots increased with Zn addition to soil.
- •
High Zn concentrations caused shoot biomass decrease, low leaf size and chlorosis.
- •
Asc-glut cycle plays a main role in detoxification of H2O2 in C. monspeliensis.
- •
AsA has a direct role in the stabilisation of carotenoids in C. monspeliensis.
