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.

Phytostabilization Potential of Yard long bean in Removing Cadmium from Soil
S. Deivanai,R. Thulasyammal +1 more
TL;DR: Owing to the crop’s adaptability to high temperature, drought conditions and ability to retain Cd in roots makes it a promising candidate for phytostabilization of soil contaminated by Cd.
Soil cadmium regulates antioxidases in sorghum.
TL;DR: The results showed that low concentrations of Cd2+ induced the activities of 4 antioxidases in leaves of the 3 species of sorghum, but high Cd 2+ concentrations significantly reduced the Activities of all the four antioxidases.

Potentially toxic elements in macromycetes and plants from areas affected by antimony mining
Ivona Kautmanová,Ondrej Brachtýr,Eliška Štubňová,Eliška Štubňová,Dana Szabóová,Peter Šottník,Bronislava Lalinská-Voleková +6 more
TL;DR: Based on the results, Cardamine amara belongs to accumulators of potentially toxic elements, and the consumption of edible mushrooms and medicinal plants from the studied localities is not recommended, as they may pose a risk of intoxication for humans.

Oxidative stress, antioxidants and stress tolerance
TL;DR: Key steps of the signal transduction pathway that senses ROIs in plants have been identified and raise several intriguing questions about the relationships between ROI signaling, ROI stress and the production and scavenging ofROIs in the different cellular compartments.
