abstract

• Cadmium (Cd) is one of the most important contaminants in the environment, it accumulates at toxic levels in different organisms. Macrophytes are macroscopic vegetation that inhabit different aquatic ecosystems, including sites contaminated with Cd. Cadmium can affect different morphological, physiological, biochemical, and molecular processes in macrophytes. Although Cd is toxic, most aquatic macrophytes have developed different strategies to minimize the damage caused by Cd ions. These strategies consist of restricting the uptake of Cd ions by the root (exclusion mechanism), storing Cd ions inside the plant in a non-toxic way (detoxification mechanism), or reducing oxidative stress through synthesizing metabolites and antioxidant enzymes. This chapter describes the toxic effects observed in macrophytes exposed to Cd and some mechanisms used by these plants to tolerate Cd stress. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
