摘要:
在酸性土壤中，植物会受到铝的毒害，从而严重影响植物的生长发育；而一些物种能耐受铝的毒害，使其在酸性土壤中正常生长。大量研究表明，植物生理水平的耐铝机制包括外部排斥机制和内部耐受机制2个方面：外部机制主要包括细胞分泌有机酸对Al1，2，33+螯合、提高根际周围pH值、降低根尖细胞壁的果胶含量等；内部机制主要是产生的有机酸与进入细胞内的Al1，2，33+螯合和细胞内部将Al1，2，33+区隔化，同时抗氧化代谢过程和激素信号转导过程也发挥着重要的作用。在分子水平上主要发现了与有机酸分泌相关的基因以及与内部忍受机制相关的耐铝基因，调控相关耐铝基因的转录因子也相继被报道。本文对植物所涉及的各种耐铝机制进行了综述，以期为培育耐铝植物提供理论基础。
