Engineering Anaerobic Metabolic Branch Points to Control Carbon Allocation Between Wax Ester Synthesis and Succinate Accumulation in Euglena gracilis
Under anaerobic conditions, Euglena gracilis degrades paramylon and synthesizes wax esters (WEs) while accumulating succinate in the culture supernatant. Succinate can either be converted to succinyl‐CoA by succinyl‐CoA synthetase (SCS) ...

Spatial Diversity of Marine Protists Along the Northern Norway Fjords During the Sub‐Arctic Summer
Polar coastal waters are highly complex and productive ecosystems that experience increasingly higher average water temperatures, shallower and stronger stratification, and higher glacier‐melting rates. Yet, the environmental complexity ...

Morphological, Molecular Phylogenetic, and Mitochondrial Genome Characterization of a Deep‐Branching Marine Flagellate, Katablepharis ulleungensis sp. nov. (Cryptista)
Katablepharids (or kathablepharids) are plastid‐less, biflagellate protists widely distributed in marine and freshwater environments. Here, we report a new katablepharid species, Katablepharis ulleungensis sp. nov., isolated from a black...

All Different All Equal: High Polymorphism in Nebela (Amoebozoa: Arcellinida) Revealed by Additional Sampling and Barcoding
Hyalospheniids are a conspicuous group of testate amoebae whose rich morphology has allowed their classification based on the characterization of their shells. However, recent studies showed the occurrence of convergences and phenotypic ...

Diversity of Ascetosporeans Associated With Feather Hydroids in New Caledonia
Ascetosporea is a group of parasitic protists within Endomyxa that primarily infect marine invertebrates and can cause serious damage to fishery resources such as oysters and prawns. Although approximately 50 species have been formally d...

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)
Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities assoc...

Summer 2026 Editor‐In‐Chief Message

Euglenids are microbial flagellates best known for their highly flexible photosynthetic species (e.g., Euglena gracilis ), though many heterotrophic groups remain poorly characterized at both molecular and ultrastructural levels. In part...

Discovery of an Undocumented Symbiosis Between Arcellinida and a Flagellate Using Single‐Cell Transcriptomics
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 through interactions with other species. Am...
