摘要：

海州香薷被视为一种铜矿指示植物,它具有较强的耐Cu性和吸Cu能力。近年来,国内外学者对海州香薷的耐Cu机理已开展了大量的研究并取得研究结果。笔者综述了该植物的氧化应激反应、气体交换、叶绿素荧光、耐Cu蛋白质组学,以及Cu污染土壤修复等方面的研究现状,并提出了今后可从加强该植物的耐性蛋白、耐性基因,以及添加辅助手段提高该植物的吸Cu能力等方面做出了展望,以期为深入揭示海州香薷的耐Cu机理提供了理论依据。

Abstract:

Elsholtzia harchowensis is regarded as a kind of the indicator plant of Cu, it has strong Cu-tolerance and Cu absorption ability. In recent years, the Cu tolerance mechanism of Elsholtzia harchowensis has been studied at home and abroad, and certain research results have been achieved. In this paper, the research status of Elsholtzia harchowensis was reviewed on oxidative stress, gas exchange,chlorophyll fluorescence parameters, proteomics of Cu tolerance, and Cu contaminated soil remediation. In addition, the paper suggested that further study should be conducted from the following perspectives: strengthening the study of tolerance protein and tolerance gene of Elsholtzia harchowensis, and improving the Cu-absorption ability by adding exogenous substances.

Key words: Elsholtzia harchowensis, Cu-tolerance mechanisms, research status, prospect
