Summary
This study updates the taxonomy of Euglenozoa, a diverse protist group including kinetoplastids and euglenids. It explores their varied lifestyles, symbiotic relationships, and viral infections.
Area of Science:
- Protistology
- Eukaryotic diversity
- Microbial evolution
Background:
- Euglenozoa is a diverse group of protists with varied lifestyles.
- Morphologically distinct subgroups (kinetoplastids, diplonemids, euglenids, symbiontids) are rarely studied comparatively.
- Euglenozoa forms a well-supported monophyletic group.
Purpose of the Study:
- To provide an updated taxonomy of Euglenozoa.
- To offer a comparative overview of Euglenozoa's diversity, distribution, and biology.
- To summarize knowledge on viruses and symbiotic bacteria associated with Euglenozoa.
Main Methods:
- Taxonomic revision based on latest findings.
- Compilation of representative species photos.
- Literature review on diversity, distribution, biology, viruses, and symbionts.
Main Results:
- A significantly modified taxonomy for kinetoplastids is proposed.
- Information on the diversity, distribution, and biology of various euglenozoan groups is presented.
- Current knowledge on euglenozoan viruses and bacterial symbionts is summarized.
Conclusions:
- The study provides a unified taxonomic and biological overview of the Euglenozoa.
- It highlights the need for comparative studies of morphologically distinct but related protist groups.
- It establishes a foundation for future research on euglenozoan evolution and ecology.

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Protists are diverse eukaryotic microorganisms that lack the specialized tissues of plants and animals and the chitinous cell walls of fungi. Their early divergence within Eukarya resulted in structural, functional, and ecological diversity. They are classified into supergroups such as Archaeplastida, Excavata, Amoebozoa, Rhizaria, Alveolata, and Stramenopiles, determined through genetic analysis and structural similarities.Structural and Functional AdaptationsProtists have various adaptations...

Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...
