Aluminium uptake across the root-cell plasma membrane

铝毒限制了酸性土壤上的作物生长，这些土壤占据了澳大利亚约2400万公顷的农田。石灰可以提高表层土壤的pH值，但在低投入的澳大利亚农业中，石灰往往过于昂贵。地面施石灰在改善底土酸度方面效果不佳，而且将石灰深入到剖面中的成本高得令人望而却步，而且技术上也很困难。因此，抗铝作物品种是澳大利亚可持续农业的重要组成部分。该项目将表征植物铝毒的早期触发因素，为提高作物品种的铝抗性奠定基础。了解铝毒害的生理基础将有助于改进作物育种策略。

Aluminium toxicity limits crop growth in acid soils that occupy about 24 million hectares of agricultural land in Australia. Liming can increase pH of the surface soil, but is frequently too expensive in the low-input Australian agriculture. Surface-applied lime is poorly effective in ameliorating subsoil acidity, and incorporating lime deep into the profile is prohibitively expensive and technically difficult. Hence, Al-resistant crop cultivars are important part of sustainable farming in Australia. This project will characterise early triggers of Al toxicity in plants, providing a foundation for increasing Al resistance in crop cultivars. Understanding the physiological basis of Al toxicity will lead to improved crop breeding strategies.
