Data from: Early photosynthetic eukaryotes inhabited low-salinity habitats

Patricia Sánchez-Baracaldo, John A. Raven, Davide Pisani & Andrew H. Knoll
The early evolutionary history of the chloroplast lineage remains an open question. It is widely accepted that the endosymbiosis that established the chloroplast lineage in eukaryotes can be traced back to a single event, in which a cyanobacterium was incorporated into a protistan host. It is still unclear, however, which Cyanobacteria are most closely related to the chloroplast, when the plastid lineage first evolved, and in what habitats this endosymbiotic event occurred. We present phylogenomic...

Data from: Structural reorganization of the chromatin remodeling enzyme Chd1 upon engagement with nucleosomes

The yeast Chd1 protein acts to position nucleosomes across genomes. Here, we model the structure of the Chd1 protein in solution and when bound to nucleosomes. In the apo state, the DNA-binding domain contacts the edge of the nucleosome while in the presence of the non-hydrolyzable ATP analog, ADP-beryllium fluoride, we observe additional interactions between the ATPase domain and the adjacent DNA gyre 1.5 helical turns from the dyad axis of symmetry. Binding in this...

Data from: A new subfamily classification of the Leguminosae based on a taxonomically comprehensive phylogeny

The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies. This new classification uses as its framework the most comprehensive phylogenetic analyses of legumes to date, based on plastid matK gene sequences, and including near-complete sampling of genera (698 of the currently recognised 765 genera) and ca. 20% (3696) of known species. The matK gene region has been the most...

Data from: The importance of species identity and interactions on multifunctionality depends on how ecosystem functions are valued

Eleanor M. Slade, Laura Kirwin, Thomas Bell, Christopher D. Philipson, Owen T. Lewis & Tomas Roslin
Studies investigating how biodiversity affects ecosystem functioning increasingly focus on multiple functions measured simultaneously (‘multifunctionality’). However, few such studies assess the role of species interactions, particularly under alternative environmental scenarios, despite interactions being key to ecosystem functioning. Here we address five questions of central importance to ecosystem multifunctionality using a terrestrial animal system: 1) Does the contribution of individual species differ for different ecosystem functions?; 2) Do inter-species interactions affect the delivery of single functions...

Data from: Symbioses with nitrogen-fixing bacteria: nodulation and phylogenetic data across legume genera

Michelle E. Afkhami, D. Luke Mahler, Jean H. Burns, Marjorie G. Weber, Martin F. Wojciechowski, Janet Sprent & Sharon Y. Strauss
How species interactions shape global biodiversity and influence diversification is a central – but also data-hungry – question in evolutionary ecology. Microbially-based mutualisms are widespread and could cause diversification by ameliorating stress and thus allowing organisms to colonize and adapt to otherwise unsuitable habitats. Yet the role of these interactions in generating species diversity has received limited attention, especially across large taxonomic groups. In the massive angiosperm family Leguminosae, plants often associate with root-nodulating bacteria...
