Contributors: J. Navascués *
author keywords: aluminum (Al) toxicity; metabolomics; organic acids; oxidative stress; proteomics; superoxide dismutase
TL;DR:
It is concluded that oxidative stress is not a causative factor of Al toxicity and the increased contents in roots of two powerful Al chelators, malic and 2-isopropylmalic acids, together with the induction of an Al-activated malate transporter gene strongly suggest that both organic acids are implicated in Al detoxification.

Changes induced by two levels of cadmium toxicity in the 2-DE protein profile of tomato roots
Journal of Proteomics, 73(9), 1694–1706.
Contributors: J. Rodríguez-Celma *
author keywords: Cadmium; Metabolism; Root; Tomato; Two-dimensional gel electrophoresis
MeSH headings : Cadmium / toxicity; Cadmium Poisoning / metabolism; Electrophoresis, Gel, Two-Dimensional; Gene Expression Profiling; Solanum lycopersicum / metabolism; Plant Proteins / drug effects; Plant Proteins / metabolism; Plant Roots / chemistry; Plant Roots / drug effects; Plant Roots / metabolism
TL;DR:
The results suggests that the 10 microM Cd treatment elicits proteomic responses similar to those observed in Fe deficiency, including activation of the glycolytic pathway, TCA cycle and respiration, whereas the 100 microMCd treatment responses are more likely due to true Cd toxicity.

MeSH headings : Chromatography, Liquid; Iron / metabolism; Magnetic Resonance Spectroscopy; Plant Roots / metabolism; Prunus / metabolism; Spectrometry, Mass, Electrospray Ionization
TL;DR:
The results suggest that the induction of this enzyme activity under iron deficiency, as previously shown in herbaceous plants, indicates the tolerance level of rootstocks to iron chlorosis.

Effect of oil refinery sludges on the growth and antioxidant system of alfalfa plants
Journal of Hazardous Materials, 171(1-3), 879–885.
Contributors: M. Martí *
author keywords: Alfalfa; Antioxidants; Homoglutathione; Oil refinery sludge; Oxidative stress

TL;DR:
An inhibition of alfalfa growth and an induction of oxidative stress, as indicated by an increase in protein oxidation, were found and the superoxide dismutase isoenzymes, peroxidase, and those enzymes involved in the ascorbate-glutathione cycle showed significant activity increases, parallel to an enhancement of total homoglUTathione, allowing plants being tolerant to this situation.

TL;DR:
A tri-Fe(III), tri-citrate complex (Fe(3)Cit(3)) was found in the xylem sap of Fe-deficient tomato (Solanum lycopersicum Mill. cv. 'Tres Cantos') resupplied with Fe by using an integrated mass spectrometry approach based on exact molecular mass, isotopic signature and Fe determination and retention time.
