Euglenozoan kleptoplasty illuminates the early evolution of photoendosymbiosis

This study shows that the euglenozoan Rapaza viridis uses kleptoplasts from Tetraselmis sp. for temporary photosynthesis, with evidence of horizontal gene transfer and shared mechanisms with Euglenophyceae.

Monophyly of Diverse Bigyromonadea and their Impact on Phylogenomic Relationships Within Stramenopiles

The paper generates transcriptomes from seven new Bigyromonadea species to assess their phylogenetic relationships within Stramenopiles, finding monophyly and potential links to oomycetes.

Single cell genomics reveals plastid-lacking Picozoa are close relatives of red algae

The paper uses single-cell genomics and phylogenomics to show Picozoa are closely related to red algae but lack plastids, challenging existing views on plastid evolution.

Taxonomy of the apicomplexan symbionts of coral, including Corallicolida ord. nov., reassignment of the genus Gemmocystis, and description of new species Corallicola aquarius gen. nov. sp. nov. and Anthozoaphila gnarlus gen. nov. sp. nov.

The paper describes new apicomplexan symbionts of corals, establishes a new order and family, and reassigns a genus based on phylogenetic and morphological analyses.

Heterotrophic flagellates and centrohelid heliozoans from marine waters of Curacao, the Netherlands Antilles

The paper describes the diversity of heterotrophic flagellates and centrohelid heliozoans from Curacao's marine waters, identifying new species and noting their ecological significance.

Predatory colponemids are the sister group to all other alveolates

This study uses phylogenomic analysis to show that colponemids are the sister group to all other alveolates and highlights their role in understanding alveolate evolution.

Insights into the origin of metazoan multicellularity from predatory unicellular relatives of animals

This study examines unicellular holozoans with complex life cycles and multicellular features, suggesting they provide insights into the origin of metazoan multicellularity.

Early eukaryotic origins and metazoan elaboration of MAPR family proteins

This paper traces the evolutionary origins of MAPR family proteins, showing their presence in the common ancestor of Opisthokonta and their functional diversification in animals.

Highly reduced genomes of protist endosymbionts show evolutionary convergence

The paper sequenced genomes of bacterial endosymbionts in diplonemid protists, revealing convergent genome reduction and functional adaptations across different host lineages.

Multiple independent origins of apicomplexan-like parasites

The paper identifies multiple independent origins of apicomplexan-like parasites through phylogenomic analysis of single-cell data from uncultivated species.

A new framework for the study of apicomplexan diversity across environments

This paper develops a curated reference database for apicomplexan SSU rRNA sequences and analyzes their distribution across diverse environments, revealing significant molecular diversity, especially in marine settings.

A universal set of primers to study animal associated microeukaryotic communities

The paper validates contrametazoan primers for 18S rRNA metabarcoding to specifically study animal-associated microeukaryotes, showing they reduce host contamination compared to universal primers.

Phylogeny, evidence for a cryptic plastid, and distribution of Chytriodinium parasites (Dinophyceae) infecting copepods

The paper analyzes the phylogeny and plastid characteristics of Chytriodinium parasites and maps their global distribution in oceanic plankton.
