    Aluminum (Al) toxicity is a major constraint for crops grown on acid soils. Various plant species have adopted an Al exclusion/avoidance mechanism and/or internal tolerance mechanisms to ameliorate Al toxicity. In Arabidopsis , the root organic acid exudation-based Al exclusion mechanism has been well characterized; however, no evidence for an internal Al tolerance mechanism has been reported.
