【摘要】 铝是制约酸性土壤上作物生产的主要因素。铝诱导氧化胁迫产生大量活性氧/一氧化氮,引起胞质钙超载,通过线粒体信号转导途径激发相关凋亡基因,从而引起细胞主动死亡,以减轻铝对植物的进一步毒害。本文综述了铝诱导程序性细胞死亡的信号分子、相关基因以及信号转导途径,对未来的研究方向提出了展望,为深入研究植物铝毒害机理和耐铝机制提供参考。更多还原

【Abstract】 Aluminum(Al) is a major limiting factor for crop production in acid soil.Al induces oxidative stress which generates a lot of reactive oxygen species(ROS) or nitric oxide(NO),resulting in calcium overloading. Cell death is initiated by exploding some associated-apoptosis genes through mitochondrial signal transduction pathway to decrease Al toxicity.In this paper,it is summarized signal molecular,related genes and signal transduction pathway of Al-induced programmed cell death(PCD) in plants,and the research prospects are proposed. It provides references for further research on the mechanisms of Al toxicity and Al tolerance in plants.更多还原
