Thecamoeba onigiri n. sp. (Amoebozoa, Discosea, Thecamoebida) – one more species of the genus Thecamoeba with polymorphic nuclear structure

Protistology
Thecamoeba onigiri n. sp. (Amoebozoa, Discosea, Thecamoebida) was isolated from a moss sample collected in the surroundings of Lake Baikal (Russia). The amoebae of this species belong to the striate morphotype and have a single rounded nucleus.

Soil Biodiversity Supports Agroecosystem Services Under Multiple Global Change Factors

Global Change Biology, Volume 32, Issue 8, August 2026.
Soil biodiversity is essential for maintaining healthy and productive agricultural systems under climate change. Using wheat fields exposed to up to eight global change factors, such as warming, drought, salinity, heavy metals, nitrogen addition, microplastics, pesticides, and alkalinization, we found that diverse soil communities play a critical role ...

On the morphology, biometry and biogeography of Lamtopyxis callistoma (Amoebozoa: Arcellinida) [PDF]

Biodiversity Data Journal, 2015
The ultra-structure of the shell and the morphometric variability of soil inhabiting testate amoeba Lamtopyxis callistoma from Madagascar were studied by using light- and scanning electron microscopy. The biometrical characteristic of the species was made on the basis of 75 specimens measured.

Inland Saline Lakes as Hotspots of Specialized, Nonmarine Protist Diversity: The Case of Arcellinida (Amoebozoa)

Environmental DNA
Inland saline lakes are dynamic environments with fluctuating salinity levels, sometimes reaching values higher than those of seawater. Their abiotic conditions are often extreme and more unpredictable than in marine systems, which could imply lower ...

Multilevel genomic constraints shape nuclear tRNA gene organization in plants

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Transfer RNAs (tRNAs) are essential components of the translation machinery. Their abundance and diversity shape decoding capacity as well as the efficiency and accuracy of protein synthesis. Because tRNA abundance is encoded in the genome through tDNA copy number, chromosomal organization, and cis‐regulatory sequences controlling transcription,

NAD9/NAD7 (mitochondrial nicotinamide adenine dinucleotide dehydrogenase gene): A new “Holy Grail” phylogenetic and DNA-barcoding marker for Arcellinida (Amoebozoa)? [PDF]

, 2017
Molecular phylogeny is an indispensable tool for assessing evolutionary relationships among protists. The most commonly used marker is the small subunit ribosomal RNA gene, a conserved gene present in many copies in the nuclear genomes.

PHLPP is neither a Phosphatase nor a Tumor Suppressor

BioEssays, Volume 48, Issue 7, July 2026.
PH domain leucine‐rich repeat protein phosphatases (PHLPP) have been described as Akt phosphatases and tumor suppressors for more than 20 years. Recent evidence, however, indicates that they are pseudophosphatases that lost catalytic activity more than 450 Mya. This article argues that new hypotheses are urgently needed to reorient the field.

Support for Membership and Supergroup Monophyly from “Amoebozoa”-Targeted Molecular Genealogies [PDF]

, 2013
Membership: • indicates the member taxon falls within the supergroup Amoebozoa; ○ indicates that the member taxon is excluded from the Amoebozoa clade, or no clade is formed.

(Amoebozoa: Arcellinida: Hyalospheniformes) is a new flagship testate amoeba taxon from Aotearoa (New Zealand) [PDF]

, 2021
Eukaryotic microbial diversity is known to be extensive but remains largely undescribed and uncharted. While much of this unknown diversity is composed of inconspicuous flagellates and parasites, larger and morphologically distinct protists are regularly
