摘要

人为活动增加了水生系统中的镉污染。本研究考察了pH值从4.3到7.3变化对水生植物浮萍(Lemna turionifera 5511)吸收Cd的影响。本研究采用无创微检测技术(NMT)、高效液相色谱(HPLC)和转录组分析等方法研究了不同pH条件下浮萍对Cd的吸收和草酸的代谢。结果表明，pH为6.3时，浮萍Cd积累量最高。此外，在pH为6.3的液体培养基中培养的浮萍根尖处Cd流入量更高。值得注意的是，Cd胁迫改变了浮萍根部的pH值和H þ内流，并显著上调了Na þ /H þ交换转运蛋白。此外，在Cd胁迫下，浮萍还能增强草酸分泌，并显著上调生物合成相关基因。因此，这些分析表明Na þ /H þ交换转运体和草酸可能影响Cd的积累，这为浮萍修复Cd污染提供了新的思路。

Cadmium accumulation in duckweed relates to pH and oxalate synthesis in Cd shock

Anthropogenic activities increase cadmium (Cd) pollution in aquatic systems. This study investigated how the pH change from 4.3 to 7.3 aﬀected the absorption of Cd by the aquatic plant duckweed ( Lemna turionifera 5511). Here, the noninvasive microtest technique (NMT), high-performance liquid chromatography (HPLC), and transcriptome analysis were used to study the duckweed’s Cd absorption and the oxalic acid metabolism under diﬀerent pH conditions. The results showed the highest Cd accumulation in duckweed with pH at 6.3. Furthermore, the Cd inﬂux was higher at the root tip of duckweed cultured in a liquid medium at pH 6.3. Notably, Cd stress changed the pH value and H þ inﬂux in duckweed roots, and signiﬁcantly upregulated the Na þ /H þ exchange transporters. Moreover, duckweed was shown to have enhanced oxalate acid secretion and signiﬁ-cantly upregulated biosynthesis-related genes under Cd stress. Therefore, these analyses suggest that Na þ /H þ exchange transporters and oxalic acid might aﬀect Cd accumulation, which could provide new ideas for phytoremediating Cd pollution using duckweed.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
