Abstract EN
Approximately 30% of the world’s total land area and over 50% of the world’s potential arable lands are acidic.
Furthermore, the acidity of the soils is gradually increasing as a result of the environmental problems including some farming practices and acid rain.
At mildly acidic or neutral soils, aluminium(Al) occurs primarily as insoluble deposits and is essentially biologically inactive.
However, in many acidic soils throughout the tropics and subtropics, Al toxicity is a major factor limiting crop productivity.
The Al-induced secretion of organic acid (OA) anions, mainly citrate, oxalate, and malate, from roots is the best documented mechanism of Al tolerance in higher plants.
Increasing evidence shows that the Al-induced secretion of OA anions may be related to the following several factors, including (a) anion channels or transporters, (b) internal concentrations of OA anions in plant tissues, (d) temperature, (e) root plasma membrane (PM) H+-ATPase, (f) magnesium (Mg), and (e) phosphorus (P).
Genetically modified plants and cells with higher Al tolerance by overexpressing genes for the secretion and the biosynthesis of OA anions have been obtained.
In addition, some aspects needed to be further studied are also discussed.
