Cadmium toxicity in plants
TL;DR: The role of the cell wall, the plasma membrane and the mycorrhizas as the main barriers against cadmium entrance to the cell, as well as some aspects related to phytochelatin-based sequestration and compartmentalization processes are reviewed in this paper.

Abstract: Heavy metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, evolutionary, nutritional, and environmental reasons. Plants posses homeostatic cellular mechanisms to regulate the concentration of metal ions inside the cell to minimize the potential damage that could result from the exposure to nonessential metal ions. This paper summarizes present knowledge in the field of higher plant responses to cadmium, an important environmental pollutant. Knowledge concerning metal toxicity, including mechanisms of cadmium homeostasis, uptake, transport and accumulation are evaluated. The role of the cell wall, the plasma membrane and the mycorrhizas, as the main barriers against cadmium entrance to the cell, as well as some aspects related to phytochelatin-based sequestration and compartmentalization processes are also reviewed. Cadmium-induced oxidative stress was also considered as one of the most studied topics of cadmium toxicity.

Evaluation of the Relevance of Myriophyllum alterniflorum (Haloragaceae) Cadmium-Sensitive Biomarkers for Ecotoxicological Surveys.
Raphaël Decou,Gaëlle Laloi,Mohamed Zouari,Mohamed Zouari,Pascal Labrousse,David Delmail,David Delmail +6 more
TL;DR: The aim here is to highlight the strong relationship existing between the physiological responses of Myriophyllum alterniflorum and the cadmium level over a long exposure period, and support the initial hypothesis that leads to recommending biomarker analyses over at least 2 weeks of metal exposure.

Physiological and biochemical responses of Phragmites australis to wastewater for different time duration
TL;DR: The present findings suggest that P. australis possess several enzymatic and non-enzymatic defense processes that curtail oxidative stress caused by heavy metals toxicity from wastewater and protect photosynthetic pigments from damage in the flowering stage.
