Other claims from this paper (8)
- Intervention effect Ca up to 3 mM increased citrate and malate concentrations of soybean root tap root tips in both genotypes at Al3+ activity of 4.6 microM.
- Intervention effect Mg up to 50 microM increased citrate and malate concentrations of soybean tap root tips in both genotypes at Al3+ activity of 4.6 microM.
- Intervention effect Adding 50 microM Mg to 0.8 mM CaSO4 increased citrate concentration of soybean tap root tips by 3- to 5-fold.
- Intervention effect Adding 50 microM Mg to 0.8 mM CaSO4 increased root exudation of citrate from soybean by 6- to 9-fold.
- Intervention effect Mg at 50 microM and Ca at 3 mM gave similar reductions in Al accumulation at soybean tap root tips.
- Mechanism Mg-stimulated production and efflux of citrate by roots are involved in the amelioration of Al inhibition of soybean root elongation at low Mg concentrations.
- Intervention effect Mg additions enhanced citrate efflux from Al-exposed soybean roots, exceeding malate efflux by up to 50-fold.
- Intervention effect Mg is superior to Ca in alleviating soybean Al rhizotoxicity, which predicted changes in plasma membrane Al3+ activity do not explain.
