A new collaboration will tackle major technical challenges currently limiting protist genomics, helping to unlock the potential of protist research for biomanufacturing, sustainable agriculture and environmental applications.

Symbiotic interactions involving single-celled eukaryotes have been studied for over a century. This is in part because these microbes occupy nearly all environments and have adapted to survive throu...

The 2026 call has attracted considerable interest from the research community with 21,627 applications submitted.

RAxML-NG is a widely used tool for maximum likelihood based phylogenetic inference. In the seven years since the last RAxML-NG publication, we have continuously improved and extended the code. Here, w...

Animal cells extensively remodel their cytoskeleton during differentiation and can notably switch between two major motility modes: flagellum-based swimming and actin-based crawling. We previously sho...

Abstract. Warnowiid dinoflagellates are known for possessing two of the most complex structures known in single cells: multi-projectile nematocysts and the

Comparing 18S metabarcoding of protist cultures and environmental samples with short and long read sequencing highlighted the advantages of each method. In particular, the study of 26 vineyard soil s...

Phytoplankton fix half of global CO2 annually and drive key global nutrient cycles. They depend on interactions with bacteria, viruses, and protists. Yet our understanding of these interactions remain...

Photosymbioses, or associations between heterotrophs and photoautotrophs, are widespread and indispensable in today's ecosystems. The chloroplasts of algae and land plants, which are at the heart of m...

Chloroplast-stealing ciliates evolve, increasing reliance on their prey for all aspects of metabolism, including photosynthesis.

In eukaryotes, ribosomal RNA genes (rDNA) encode the major ribosomal RNA molecules and are typically organized into a distinctive genomic structure involving tandem repetition of a polycistronic codin...

Molecular clock and preservation of early microfossil assemblages suggest that eukaryotes were present and already diverse more than ~1600 million ...

Abstract. Plastids, the photosynthetic organelles of eukaryotes, arose via endosymbiosis of cyanobacteria by a eukaryotic host and were subsequently spread

by Mechas — The ability to fix nitrogen is usually regarded as a property of only a few diazotrophic bacteria and archaea. A new study now shows that some eukaryotes may be capable of fixing nitro…
