The supergroup Amoebozoa unites a wide diversity of amoeboid organisms and encompasses enigmatic lineages that have been recalcitrant to modern phylogenetics. Deep divergences, taxonomic placement of some key taxa and character evolution in the group largely remain poorly elucidated or controversial. We surveyed available Amoebozoa genomes and transcriptomes to mine conserved putative single copy genes, which were used to enrich gene sampling and generate the largest supermatrix in the group to date; encompassing 824 genes, including gene sequences not previously analyzed.

Cochliopodium is a lens-shaped genus of Amoebozoa characterized by a flexible layer of microscopic dorsal scales. Recent taxonomic and molecular studies reported cryptic diversity in this group and suggested that the often-used scale morphology is not a reliable character for species delineation in the genus. Here, we described three freshwater Cochliopodium spp.

Thecamoebida Smirnov and Cavalier-Smith, 2011 (Discosea, Amoebozoa) has been molecularly understudied. The group until recently consisted of three genera containing species that live in terrestrial or aquatic environments. Here, we describe a fourth genus, Stratorugosa tubuloviscum gen.

Background: Transcriptome sequencing has become a method of choice for evolutionary studies in microbial eukaryotes due to low cost and minimal sample requirements. Transcriptome data has been extensively used in phylogenomic studies to infer ancient evolutionary histories. However, its utility in studying cryptic species diversity is not well explored.

Article Synopsis
  • - Microbial eukaryotes like amoeboids have complex life cycles that may involve sexual reproduction, with recent studies suggesting that the Amoebozoa group is ancestrally sexual; however, some have very low detection of sex-related genes.
  • - In the genus Cochliopodium, known for its unique processes of cell fusion and karyogamy, previous findings showed no meiosis genes; this study generates extensive transcriptome data to better understand its genetic basis and lifecycle.
  • - The study identified a higher number of sex-related genes, including previously undetected meiosis genes, revealing that Cochliopodium has the genetic tools for sexual recombination, although the specifics of its fusion and genome reduction mechanisms are still

Longamoebia is one of the most morphologically diverse member of Amoebozoa. It includes the human pathogen Acanthamoeba, which causes minor skin and serious eye infections as well as fatal central nervous system complications. The taxonomy and phylogeny of Longamoebia is poorly understood partly due to the growing number of molecular studies that report unsuspected affiliations of lineages with extremely different morphotypes in the group.

Article Synopsis
  • Sex in eukaryotes boosts genetic diversity, but its evolutionary origins, especially in the amoeboid supergroup Amoebozoa, remain unclear; recent studies hint at hidden sexual cycles within this group despite a general belief in their asexuality.* -
  • This study analyzed the genes related to meiosis in 39 different amoebozoans, revealing that while they have many meiosis genes, they lack genes for the synaptonemal complex, which is important for chromosome pairing during meiosis.* -
  • Findings indicate that not only do amoebozoans possess functional sex genes, but also suggest that the group originally had sexual reproduction, challenging the idea that asexuality is the norm and implying

Background: Influenza is a significant cause of morbidity and excess mortality, yet vaccine coverage in the UK remains below target. Community pharmacies are increasingly being promoted as an alternative to vaccination by GPs.

Aim: To explore and verify the factors that influence the relative performance of pharmacies providing NHS influenza vaccinations.
