Diversity of the Amoebozoa and Ciliophora Groups in Non-Human Primates Kept Ex Situ and in Their Handlers in Different Institutions in Brazil [PDF]

Pathogens
Parasitic infections in non-human primates (NHPs) kept ex situ can be caused by zoonotic protists like Balantioides coli and Entamoeba histolytica. In Brazil, little is known about these infections in neotropical species.

Evolution of microRNAs in Amoebozoa and implications for the origin of multicellularity. [PDF]

Nucleic Acids Res, 2023
MicroRNAs (miRNAs) are important and ubiquitous regulators of gene expression in both plants and animals. They are thought to have evolved convergently in these lineages and hypothesized to have played a role in the evolution of multicellularity. In line

New insights on the evolutionary relationships between the major lineages of Amoebozoa [PDF]

Scientific Reports, 2022
The supergroup Amoebozoa unites a wide diversity of amoeboid organisms and encompasses enigmatic lineages that have been recalcitrant to modern phylogenetics.

The evolution of gene functional repertoire in Amorphea: divergent strategies across Amoebozoa, Fungi, and Metazoa. [PDF]

Mol Biol Evol
Metazoa and Fungi have been extensively studied to reconstruct the trajectory of Opisthokont evolution. Their sister group, Amoebozoa, provides additional potential to generate valuable insights into the origins of Opisthokont lineages.

A Novel Protistan Trait Database Reveals Functional Redundancy and Complementarity in Terrestrial Protists (Amoebozoa and Rhizaria). [PDF]

Mol Ecol Resour
The inclusion of functional traits of protists in environmental sequencing surveys, in addition to the traditional taxonomic framework, is essential for a better understanding of their roles and impacts on ecosystem processes.

Protistan Predators Outshine Fungi in Forest Soil Activity. [PDF]

J Eukaryot Microbiol
ABSTRACT Despite extensive research on fungal communities in forest soils, our understanding of the whole eukaryotic diversity and distribution remains limited. Moreover, traditional amplicon sequencing methods often introduce severe PCR and primer biases, further hindering accurate assessment of the microbial community composition in forest soils.

From Molecules to Amoeboid Movement: A New Way for Understanding the Morphology Through Actin-Binding Proteins [PDF]

Biomolecules
Amoebozoa is a group of single-celled organisms that change their shape during locomotion. However, there is a taxon-specific complex of morphological characters inherent in the moving amoebae, known as locomotive forms. Actin is one of the proteins most

Investigations into the Diversity and Distribution of tRNA and Phylogenetics of Translation Factors in Amoebozoa-Infecting <i>Nucleocytoviricota</i>. [PDF]

Viruses
Translation is a sine qua non process for life as we know it. Translation factors (TFs) and tRNAs are rare among viruses but are commonly found in giant viruses of the class Megaviricetes.

Experimental approach on the contribution of wind and animal vectors in the dispersal and colonization of testate amoebae (Protista, Amoebozoa) in freshwater ecosystems [PDF]

Acta Limnologica Brasiliensia
: Aim We aimed to understand how testaceous amoebae spread in new sites, assessing their dispersal potential by wind and animals in freshwater ecosystems. Methods We conducted a field experiment over 33 days between July and August 2018.

New records of fimicolous myxomycetes for the Pampa biome, Brazil, and a new occurrence for the Americas [PDF]

Scientific Reports
Dung represents an important survival resource for a wide range of microorganisms, including free–living Amoebozoa such as Myxomycetes. This group encompasses just over 1,000 morphologically recognizable species, occupying different ecological niches ...
