TL;DR: Current knowledge about the phloem transport mechanisms is summarized and the effects of several abiotic (water and salt stress, mineral deficiency, CO2, light, temperature, air, and soil pollutants) and biotic andmutualistic and pathogenic microbes, viruses, aphids, and parasitic plants are reviewed.
Journal ArticleDOI
Plant science: the key to preventing slow cadmium poisoning
TL;DR: Recent studies on rice (Oryza sativa) and Cd-hyperaccumulating plants that have led to important insights into the processes controlling the passage of Cd from the soil to edible plant organs are reviewed.

Toxic Heavy Metal and Metalloid Accumulation in Crop Plants and Foods
Stephan Clemens,Jian Feng Ma +1 more
TL;DR: Proteins mediating the uptake of arsenic and cadmium have been identified, and the speciation and biotransformations of arsenic are now understood, and factors controlling the efficiency of root-to-shoot translocation and the partitioning of toxic elements through the rice node have also been identified.

Arsenic toxicity: The effects on plant metabolism
Patrick M. Finnegan,Weihua Chen +1 more
TL;DR: The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up by the cells of the plant root Once in the cell, AsV can be readily converted to AsIII, the more toxic of the two forms AsV and AsIII both disrupt plant metabolism, but through distinct mechanisms as mentioned in this paper.

A simple, fast, and accurate algorithm to estimate large phylogenies by maximum likelihood.
Stéphane Guindon,Olivier Gascuel +1 more
TL;DR: This work has used extensive and realistic computer simulations to show that the topological accuracy of this new method is at least as high as that of the existing maximum-likelihood programs and much higher than the performance of distance-based and parsimony approaches.
Journal ArticleDOI
MAFFT: a novel method for rapid multiple sequence alignment based on fast Fourier transform
TL;DR: A simplified scoring system is proposed that performs well for reducing CPU time and increasing the accuracy of alignments even for sequences having large insertions or extensions as well as distantly related sequences of similar length.
Journal ArticleDOI
Toxic metal accumulation, responses to exposure and mechanisms of tolerance in plants
TL;DR: This review discusses the molecular mechanisms of toxic metal accumulation in plants and algae, the responses to metal exposure, as well as the understanding of metal tolerance and its evolution.

Transporters of arsenite in rice and their role in arsenic accumulation in rice grain
Jian Feng Ma,Naoki Yamaji,Namiki Mitani,Xiao-Yan Xu,Yu-Hong Su,Steve P. McGrath,Fang-Jie Zhao +6 more
TL;DR: It is reported that two different types of transporters mediate transport of arsenite, the predominant form of arsenic in paddy soil, from the external medium to the xylem, which explains why rice is efficient in arsenic accumulation.
Journal ArticleDOI
"Heavy metals" a meaningless term? (IUPAC Technical Report)
TL;DR: In this article, a new classification of heavy metals based on the periodic table is proposed, which should reflect our understanding of the chemical basis of toxicity and allow toxic effects to be predicted.
