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

铝是世界各地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问题。铝对植物细胞的毒害机制还不清楚。本项目旨在阐明铝对植物毒害中细胞内钙稳态和质膜电位之间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开展旨在选择对铝毒性具有更高抗性的作物基因型的育种计划。

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.
