New ‪preprint! Through plastid MAGs and 18S rRNA gene retrieval 🧬 we identify chromerids (including a novel clade ⭐) associated with marine and freshwater microbialites across the globe 🌎, expanding their ecological niche beyond coral reefs 🪸. #ProtistsOnSky #MicroSky #Algae
Modern microbialites harbor an undescribed diversity of chromerid algae
Chromerid algae and the heterotrophic colpodellids together make up the chrompodellids, which are the closest known relatives to apicomplexan parasites [1]. As apicomplexans are prolific parasites of ...

🌟 New book chapter alert!

🪸 Coral reefs are threatened by climate change, especially by mass ‘bleaching’ events. Bleaching is caused by the loss of photosymbionts under stress, resulting in a white – ‘bleached’ - phenotype.

Bleaching of Reef Organisms: Current Knowledge, Challenges, and Future Directions into the Anthropocene
Coral reefs worldwide are threatened by climate change and other anthropogenic stressors. A global factor contributing to coral reef decline is the increasing frequency, duration, and intensity of bleaching events leading to extensive mortality of keystone species,...

metaPR2 version 3.0 has just been released.

Here are the major changes:
- Metabarcodes (ASVs) are now annotated with the latest version of the PR2 reference sequence database (5.1.0).
- 8 new published datasets have been added from the Arctic and from the South West Pacific.

How do #apicomplexans reorganize their #PlasmaMembrane (PM) while replicating inside host cells? This study shows that #Toxoplasma recycles its PM via Rab5b- & MyoF-dependent #endocytosis, linking PM reservoir formation to membrane homeostasis via the micropore @plosbiology.org 🧪 plos.io/46tDxny
Formation and dynamics of the plasma membrane reservoir (PMR). The PMR forms prior to the development of the daughter cells’ IMC. Its position and size vary during replication, and it is reabsorbed at the conclusion of daughter cell budding. We propose that the PMR facilitates the expansion of the PM surface during replication. All scale bars represent 1 µm. While the PMR is not always visible due to its transient nature, virtually all the parasites undergoing replication are forming a PMR.
