The LARP6 La module from Tetrabaena socialis reveals structural and functional differences from plant and animal LARP6 homologues

RNA Biology
This study identified the LARP6 La Module from Tetrabaena socialis (T. socialis), a four-celled green algae, in an effort to better understand the evolution of LARP6 structure and RNA-binding activity in multicellular eukaryotes.

Information Transfer During Food Choice in the Slime Mold Physarum polycephalum

Frontiers in Ecology and Evolution, 2019
Throughout evolution, living systems have developed mechanisms to make adaptive decisions in the face of complex and changing environmental conditions. Most organisms make such decisions despite lacking a neural architecture.

Hsp70 diversification and repurposing across the tree of life: Lessons from the evolutionary and mechanistic trajectory of the Hsp70–Hsp110 chaperone system

The FEBS Journal, EarlyView.
Evolutionary and mechanistic divergence in the Hsp70–Hsp110 chaperone system. Prokaryotic Hsp70s probably diversified into multiple orthologues that cooperated with co‐chaperones such as JDPs and NEF, forming increasingly complex proteostasis networks.

Inter-annual depth-dependent toxicity and bioaccumulation of cadmium in marine benthic protist communities

Oceanologia, 2007
The toxicity and bioaccumulation of cadmium in a marine benthic protist community were examined at different depths within the sediment. For this purpose, sediment-water microcosms with 1000 µg Cd dm-3 of the pollutant were used in two assays.

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Responses of soil microeukaryotic communities to short-term fumigation-incubation revealed by MiSeq amplicon sequencing

Frontiers in Microbiology, 2015
In soil microbiology, there is a ‘paradox’ of soil organic carbon (SOC) mineralization, which is that even though chloroform fumigation destroys majority of the soil microbial biomass, SOC mineralization continues at the same rate as in the non-fumigated

Provenance legacies override species effects in shaping oak rhizosphere microbiomes and metabolomes

New Phytologist, EarlyView.
Graphical representation of experimental setup. Quercus spp. seeds were collected at two origins: upper Rhine basin (URB) and north German lowland (NGL). Summary As climate change drives more frequent drought‐heat extremes, selecting drought‐tolerant trees is crucial for future forest resilience. However, the role of tree–microbial associations remains

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?

Plant, Cell &Environment, EarlyView.
ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Biology of the Marine Heterotrophic Dinoflagellate Oxyrrhis marina: Current Status and Future Directions

Microorganisms, 2013
Heterotrophic dinoflagellates are prevalent protists in marine environments, which play an important role in the carbon cycling and energy flow in the marine planktonic community.
