Synchrony of Eukaryotic and Prokaryotic Planktonic Communities in Three Seasonally Sampled Austrian Lakes

Frontiers in Microbiology, 2018
Freshwater systems are characterized by an enormous diversity of eukaryotic protists and prokaryotic taxa. The community structures in different lakes are thereby influenced by factors such as habitat size, lake chemistry, biotic interactions, and ...

Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Volatile organic compounds orchestrating microbiome‐mediated crop resilience: Prospects and challenges for sustainable agriculture

Journal of Integrative Plant Biology, EarlyView.
Herbivory triggers the production of green leaf volatiles, and dense planting results in induces increased concentration of linalool emission in maize canopies. These volatiles activate plant‐soil feedback that enriches beneficial rhizosphere bacteria, enhancing resistance, though sometimes at a growth cost, thereby offering new avenues for sustainable

Encystation commitment in Giardia duodenalis: a long and winding road

Parasite, 2009
Cholesterol and bile salts are relevant modulators of Giardia encystation. Although several molecules within signaling cascades have been identified, and changes in their expression observed during giardial encystation, their underlying interactions ...

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.

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, EarlyView.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

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.
