Interpretive Summary: Aluminum (Al) toxicity is a major constraint for crop growth and yield on acid soils. Therefore understanding how plants cope with Al stresses is critical for crop production on acid soils. Plants have evolved an exclusion tolerance mechanism and an internal detoxification mechanism to fight against Al stresses via root exudation of organic matters. However, the interactions between these two mechanisms remain unknown. Here, we report on the discovery that the establishment of an exclusion mechanism is essential for the function of an internal detoxification mechanism in Arabidopsis. We discuss and emphasize the previously unrecognized roles of the root cell wall in Al resistance in plants. The paper describes significant process towards our understandings of the mechanisms and their interactions that underlie Al resistance in plants.
Technical Abstract: Previous studies has demonstrated the significance of the coordinated activity between an exclusion mechanism and an internal detoxification mechanism in Al resistance in plants. However, the relationship between these two mechanisms in Al resistance remains unclear. In this study, we demonstrate that the exclusion mechanism and the internal detoxification function in a same biochemical pathway where the exclusion mechanism acts in earlier steps than does the internal detoxification mechanism.
