A communal catalogue reveals Earth’s multiscale microbial diversity
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.

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.

An overview of current knowledge on Se cycling with a specific focus on soil-plant-atmosphere interfaces is given and sources, speciation and mobility of Se in soils and plants will be discussed as well as Se hyperaccumulation by plants, biofortification and biomethylation.
Phytoremediation of Metals Using Transgenic Plants
Results from lab and greenhouse studies look promising for several of these transgenics for environmental cleanup, but field studies will be the ultimate test to establish their phytoremediation potential, their competitiveness, and risks associated with their use.
Selenium Metabolism in Plants
The review of plant Se metabolism is given, new insights into plant Se tolerance and hyperaccumulation mechanisms are presented, and research on the ecological aspects of Plant Se accumulation are summarized.

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.

Se was shown to protect Indian mustard plants from fungal infection and from herbivory by caterpillars, but not by snails.
CpSufE Activates the Cysteine Desulfurase CpNifS for Chloroplastic Fe-S Cluster Formation*
