Molecular mechanisms governing the role of calcium in aluminium toxicity and tolerance in plants

铝是全球酸性土壤中最重要的产量限制因子。耕地的持续酸化加剧了铝毒性问题。铝在植物细胞中的毒性机制尚不清楚。本项目旨在阐明植物铝毒性中细胞内钙稳态与质膜电位相互作用的分子基础。了解铝毒性的主要触发因素将有助于育种计划，以选择对铝毒性抗性增强的作物基因型。

Aluminium is the most important yield-limiting factor in acid soils throughout the world. The problem of aluminium toxicity is aggravated by continuous acidification of arable land. Mechanisms of aluminium toxicity in plant cells are poorly understood. The present project seeks to elucidate the molecular basis of the interaction between intracellular calcium homeostasis and plasma membrane potential in aluminium toxicity to plants. Knowledge of primary triggers of aluminium toxicity will pay off in a breeding programme aimed at selecting crop genotypes with increased resistance to aluminium toxicity.
