Cadmium tolerance and accumulation in Indian mustard is enhanced by overexpressing gamma-glutamylcysteine synthetase.
TLDR
It is concluded that overexpression of gamma-ECS increases biosynthesis of glutathione and PCs, which in turn enhances Cd tolerance and accumulation, and appears to be a promising strategy for the production of plants with superior heavy metal phytoremediation capacity. Expand
Selenium in higher plants: understanding mechanisms for biofortification and phytoremediation.
TLDR
Key developments in the current understanding of Se in higher plants are reviewed and recent advances in the genetic engineering of Se metabolism are discussed, particularly for biofortification and phytoremediation of Se-contaminated environments. Expand
A communal catalogue reveals Earth’s multiscale microbial diversity
TLDR
A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity. Expand
Physiological functions of beneficial elements.
TLDR
The beneficial effects of low doses of Al, Co, Na, sodium, selenium, Se and Se have received little attention compared to toxic effects that typically occur at higher concentrations. Expand
Analysis of transgenic Indian mustard plants for phytoremediation of metal-contaminated mine tailings.
TLDR
This study is the first to demonstrate enhanced phytoextraction potential of transgenic plants using polluted environmental soil and confirms the importance of metal-binding peptides for plant metal accumulation and shows that results from hydroponic systems have value as an indicator for phytoremediation potential. Expand
Phytoremediation of Metals Using Transgenic Plants
An ideal plant for environmental cleanup can be envisioned as one with high biomass production, combined with superior capacity for pollutant tolerance, accumulation, and/or degradation, depending onExpand
CpSufE Activates the Cysteine Desulfurase CpNifS for Chloroplastic Fe-S Cluster Formation*
TLDR
CpNifS and CpSufE together form a cysteine desulfurase required for iron-sulfur cluster formation in chloroplasts, which is characterized and found to be light-dependent and regulated at the mRNA level. Expand
Metallophytes—a view from the rhizosphere
TLDR
The role of the root as an effective trace element scavenger through interactions in the rhizosphere is highlighted and ways in which this knowledge can be applied and improved are suggested. Expand
Selenium accumulation protects Brassica juncea from invertebrate herbivory and fungal infection.
TLDR
Se was shown to protect Indian mustard plants from fungal infection and from herbivory by caterpillars, but not by snails. Expand
Molecular Mechanisms of Selenium Tolerance and Hyperaccumulation in Stanleya pinnata1[W][OA]
TLDR
Defense-related phytohormones may play an important signaling role in the Se hyperaccumulation of S. pinnata, perhaps by constitutively up-regulating sulfur/Se assimilation followed by methylation of selenocysteine and the targeted sequestration of methylselenocysteines. Expand
