水稻耐铝毒机制研究进展

Progress on the Mechanism of Aluminum Tolerance in Rice

铝毒是酸性土壤中植物生长的重要限制因子。水稻是最耐铝毒的小谷粒禾本科农作物之一,其耐性机理至今仍不十分清楚。主要概述了植物铝毒的症状和耐性机制,以及水稻铝毒耐性分子机理的最新研究现状。

Aluminum （Al） toxicity is the major factor limiting crop production on acidic soils. Rice （Oryza sativa L.） is one of the most Al resistant species among the small-grain cereal crops, but the mechanisms for Al tolerance are still poorly understood. In the present review, we summarized the symptoms of Al toxicity, the mechanisms of plant to Al tolerance, and the recent progress on the molecular mechanisms underlying Al tolerance in rice.
