Physiological and Molecular Regulation of Aluminum Resistance in Woody Plant Species
- Aluminum (Al) is the main limiting factor for plant growth in acid soils. Woody plant species are well adapted to acid soils with high Al3+ concentration. The external resistance mechanisms comprise Al immobilization in the rhizosphere (Al excluders) and internal ones include complexation of Al in cells (Al accumulators). This chapter provides a critical analysis of the physiological and molecular regulation of Al-resistance mechanisms in woody plant species.
