TL;DR: The molecular mechanisms responsible for selenium tolerance and hyperaccumulation were studied in the Se hyper-accumulator Stanleya pinnata (Brassicaceae) by comparing it with the related secondary Se accumulator S. albescens using a combination of physiological, structural, genomic, and biochemical approaches.

TL;DR: By mapping the occurrence of hyperaccumulators onto the angiosperm phylogeny, it is shownhyperaccumulation has had multiple origins across theAngiosperms and whether there is evidence for co-evolution with ecological partners is addressed.

TL;DR: 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.

TL;DR: The finding that Se protected the two hyperaccumulator species from both cell disruptors lends further support to the elemental defense hypothesis and increases the number of herbivores and feeding modes against which Se has shown a protective effect.

TL;DR: This work uses genomic resources from 43 angiosperm species to develop enrichment probes useful for collecting ~500 loci from non-model taxa across the diversity of angiosperms, and presents a method that generates a heat map for each node on a phylogeny that reveals the sensitivity of support for the node across analysis conditions, as well as different locus, site, and taxon schemes.
