Author Correction: Inference and reconstruction of the heimdallarchaeial ancestry of eukaryotes - Nature
Correction to: Nature https://doi.org/10.1038/s41586-023-06186-2 Published online 14 June 2023 Our manuscript included a phylogenomic study of the evolutionary relationship between eukaryotes and Asgard archaea, showing that eukaryotes likely emerged from a bona fide Asgard archaeal ancestor. Our results suggested that eukaryotes and the heimdallarchaeial order Hodarchaeales form a monophyletic group. A set of 57 phylogenetic markers (NM57) was central to reach these conclusions.
Seasonal dynamics and diversity of Antarctic marine viruses reveal a novel viral seascape - Nature Communications
Abstract The Southern Ocean microbial ecosystem, with its pronounced seasonal shifts, is vulnerable to the impacts of climate change. Since viruses are key modulators of microbial abundance, diversity, and evolution, we need a better understanding of the effects of seasonality on the viruses in this region.
Inference and reconstruction of the heimdallarchaeial ancestry of eukaryotes - Nature
Abstract In the ongoing debates about eukaryogenesis—the series of evolutionary events leading to the emergence of the eukaryotic cell from prokaryotic ancestors—members of the Asgard archaea play a key part as the closest archaeal relatives of eukaryotes1. However, the nature and phylogenetic identity of the last common ancestor of Asgard archaea and eukaryotes remain unresolved2,3,4.
Gene gain facilitated endosymbiotic evolution of Chlamydiae - Nature Microbiology
Abstract Chlamydiae is a bacterial phylum composed of obligate animal and protist endosymbionts. However, other members of the Planctomycetes–Verrucomicrobia–Chlamydiae superphylum are primarily free living. How Chlamydiae transitioned to an endosymbiotic lifestyle is still largely unresolved. Here we reconstructed Planctomycetes–Verrucomicrobia–Chlamydiae species relationships and modelled superphylum genome evolution.
The evolutionary origin of host association in the Rickettsiales - Nature Microbiology
Abstract The evolution of obligate host-association of bacterial symbionts and pathogens remains poorly understood. The Rickettsiales are an alphaproteobacterial order of obligate endosymbionts and parasites that infect a wide variety of eukaryotic hosts, including humans, livestock, insects and protists. Induced by their host-associated lifestyle, Rickettsiales genomes have undergone reductive evolution, leading to small, AT-rich genomes with limited metabolic capacities.
Belowground fungal community diversity and composition associated with Norway spruce along an altitudinal gradient
Abstract Altitudinal gradients provide valuable information about the effects of environmental variables on changes in species richness and composition as well as the distribution of below ground fungal communities. Since most knowledge in this respect has been gathered on aboveground communities, we focused our study towards the characterization of belowground fungal communities associated with two different ages of Norway spruce (Picea abies) trees along an altitudinal gradient.
