摘　要：

酸性土壤是世界范围内降低植物产量的非生物因素之一, 其中限制植物生长的主要因素是可溶性的Al³⁺, 其在微摩尔浓度下就可抑制植物生长。植物主要通过外部排斥和内部耐受机制来抵御Al³⁺毒害。本综述主要从这两个方面介绍了目前已经报道的一些耐铝基因的研究进展和这些基因的转录调控以及影响这些基因表达的因素。

Abstract:

Acid soils is a major abiotic factor that restrict plant production around the world. One of the major limitations to plant growth on acid soils is the prevalence of soluble aluminum (Al³⁺) ions which can inhibit root growth at micromolar concentrations. Plants have evolved mechanisms tocope with Al3+ and these can be broadly divided into external exclusion and internal tolerance. In this review, we describe the genes involving in Al³⁺ tolerance in these two mechanisms. We also focus on recent insights into the transcriptional regulation of these and other genes involved in Al³⁺ tolerance and discuss the pathways coordinating their expression in plant.

Key words: acid soils; Al³⁺ tolerance genes; organic acid; transporter protein
