Abstract

Copper (Cu) is a vital trace element necessary for plants growth and development. It acts as a co-factor for enzymes and plays a crucial role in various physiological processes, including photosynthesis, respiration, antioxidant systems, and hormone signaling transduction. However, excessive amounts of Cu can disrupt normal physiological metabolism, thus hindering plant growth, development, and reducing yield. In recent years, the widespread abuse of Cu-containing fungicides and industrial Cu pollution has resulted in significant soil contamination. Therefore, it is of utmost importance to uncover the adverse effects of excessive Cu on plant growth and delve into the molecular mechanisms employed by plants to counteract the stress caused by excessive Cu. Recent studies have confirmed the inhibitory effects of excess Cu on mineral nutrition, chlorophyll biosynthesis, and antioxidant enzyme activity. This review systematically outlines the ways in which plants tolerate excessive Cu stress and summarizes them into eight Cu-tolerance strategies. Furthermore, it highlights the necessity for further research to comprehend the molecular regulatory mechanisms underlying the responses to excessive Cu stress.

植物耐铜机制的进展。

铜（Cu）是植物生长和发育所必需的重要微量元素。它是酶的辅助因子，在光合作用、呼吸作用、抗氧化系统和激素信号转导等各种生理过程中起着至关重要的作用。然而，过量的铜会破坏正常的生理代谢，从而阻碍植物的生长发育并降低产量。近年来，含铜杀菌剂的广泛滥用和工业铜污染已造成严重的土壤污染。因此，揭示过量铜对植物生长的不利影响，并深入研究植物抵御过量铜造成的胁迫的分子机制至关重要。最近的研究证实，过量的铜对矿物质营养、叶绿素生物合成和抗氧化酶活性有抑制作用。本综述系统地概述了植物耐受过量铜胁迫的方式，并将其归纳为八种耐铜策略。此外，它还强调了进一步研究的必要性，以了解对过量铜胁迫反应的分子调控机制。

期刊介绍： Plant Science will publish in the minimum of time, research manuscripts as well as commissioned reviews and commentaries recommended by its referees in all areas of experimental plant biology with emphasis in the broad areas of genomics, proteomics, biochemistry (including enzymology), physiology, cell biology, development, genetics, functional plant breeding, systems biology and the interaction of plants with the environment. Manuscripts for full consideration should be written concisely and essentially as a final report. The main criterion for publication is that the manuscript must contain original and significant insights that lead to a better understanding of fundamental plant biology. Papers centering on plant cell culture should be of interest to a wide audience and methods employed result in a substantial improvement over existing established techniques and approaches. Methods papers are welcome only when the technique(s) described is novel or provides a major advancement of established protocols.
