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.
Tryonia, a new taenitidoid fern genus segregated from Jamesonia and Eriosorus (Pteridaceae)
TLDR
It is shown that several species traditionally treated in Eriosorus are in fact more closely related to other taenitidoid fern genera (namely Austrogramme, Pterozonium, Syngramma, and Taenitis) than they are to the large Jamesonia sensu lato clade.
A revised generic classification of vittarioid ferns (Pteridaceae) based on molecular, micromorphological, and geographic data
TLDR
A revised generic classification of vittarioid ferns (Pteridaceae) based on molecular, micromorphological, and geographic data is presented.
Selenium hyperaccumulators harbor a diverse endophytic bacterial community characterized by high selenium resistance and plant growth promoting properties
TLDR
It is concluded that Se hyperaccumulators harbor an endophytic bacterial community in their natural seleniferous habitat that is equally diverse to that of comparable non-accumulator communities.
Plant Selenium Hyperaccumulation Affects Rhizosphere: Enhanced Species Richness and Altered Species Composition
TLDR
Se hyperaccumulation does not appear to negatively affect rhizobacterial diversity, and may select for certain taxa in the rhizosphere microbiome, but Se resistance inhyperaccumulator-associated bacteria and archaea may be widespread and not under selection by the host plant.
Selenium and the Plant Microbiome
TLDR
Investigations have isolated a variety of microbes from plants or soil in seleniferous areas including bacteria and fungi with enhanced Se tolerance, which shows promise for applications in phytoremediation or biofortification.
