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.

Aluminium accumulation in excess and related anti-oxidation responses in C 4 weed ( Amaranthus viridis L.)
TL;DR: Plant extract was satisfactorily potential under in vitro anti-oxidation systems through assay of 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS), ferric chelation activity etc and would be a bioprospecting in role likely involved in phytoremediation of metal.

A Quantitative Approach for Cd, Cu, Fe and Mn Through Laser Ablation Imaging for Evaluating the Translocation and Accumulation of Metals in Sunflower Seeds
Gustavo de Souza Pessôa,Cícero Alves Lopes Júnior,Katherine Chacón Madrid,Marco Aurélio Zezzi Arruda,Marco Aurélio Zezzi Arruda +4 more
TL;DR: Results indicated that cadmium is translocated to seeds, and the cotyledons showed the highest concentration (Cd-high group), ranging from 10 to 20µgg-1, which highlights the importance of bioimaging evaluation, in the translocation and accumulation of metals, contributing to expand the information available of this culture.
