Multigene phylogeny resolves deep branching of Amoebozoa

Molecular Phylogenetics and Evolution, 2015
Amoebozoa is a key phylum for eukaryote phylogeny and evolutionary history, but its phylogenetic validity has been questioned since included species are very diverse: amoebo-flagellate slime-moulds, naked and testate amoebae, and some flagellates. 18S rRNA gene trees have not firmly established its internal topology.

Pyrumthecina Infraorder Nov.: Revisiting the morphological diversity and identifying the phylogenetic home of Argynnia within Arcellinida (Tubulinea:Amoebozoa)

bioRxiv
Arcellinida is a diverse lineage of testate amoebae within Amoebozoa, whose evolutionary history has been clarified through phylogenomics. These efforts have led to a stable classification of the group into suborders and infraorders.

Leptomyxa xiamenii n. sp. – the first species of the genus Leptomyxa (Amoebozoa, Tubulinea, Leptomyxida) described from China

Protistology
The genus Leptomyxa (Amoebozoa, Tubulinea, Leptomyxida) includes both nonreticular and reticular amoebae. Some of them are able to alter the shape of the cell from monopodial to flattened. To date, this genus includes 13 valid species.

Conformational diversity in poly‐HAMP arrays and its implications for signal transduction

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Prokaryotic transmembrane receptors are built around a helical coiled‐coil backbone, with sensory, modulatory, and effector domains arranged along its length. The modulatory HAMP domain forms a parallel four‐helix coiled coil integrated into this backbone, typically connecting transmembrane segments with downstream cytosolic domains.

Accurate Identification of Key Groups of Microeukaryotes Using Multimodal Deep Learning: An Integrated Classification Model Combining Morphological and Molecular Data

Molecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT Traditional classification of flagellates (i.e., flagellated protists) relies on morphological traits or a single molecular marker, which suffer from subjectivity and limited data sources. This study proposes a multimodal deep learning model, Residual Multi‐Feature Attention‐50 (ResMFA50), that integrates photomicrographs and small subunit ...
