铝诱导有机酸分泌的耐铝机理研究进展

铝毒是限制酸性土壤中植物生长和作物生产以及森林退化的主要因子。为了能在有铝毒害的环境下生长，植物进化出一系列的耐铝毒机制。铝诱导下有机酸分泌解铝毒是植物耐铝研究的一个热门领域。本研究综述了植物根系分泌有机酸的种类以及有机酸解铝毒的机理，并从有机酸通道蛋白基因鉴定、克隆以及功能分析等方面进行综述；同时指出植物耐铝毒是多基因控制的复杂特性，因此，从耐铝基因的表达调控方面进行深入研究，将有效揭示植物抗铝的机制。

The Improvement of Mechanism of Detoxification of Aluminum for Organic Acids

Aluminum toxicity is the main reason to limit the plant growth in acidic soil and forest degradation. In the acid soil, some plant species and cultivars have evolved some mechanisms for detoxifying Al both internally and externally. Some evidences have shown that organic acids play an important role in the detoxification of Al, organic Acids channel protein gene were identified and cloned. This paper would provide a good idea for future research.
