The multicellularity genes of dictyostelid social amoebas [PDF]
, 2016 The evolution of multicellularity enabled specialization of cells, but required novel signalling mechanisms for regulating cell differentiation. Early multicellular organisms are mostly extinct and the origins of these mechanisms are unknown.

Comparative Genomics Supports Sex and Meiosis in Diverse Amoebozoa [PDF]
Genome Biology and Evolution, 2018 Sex and reproduction are often treated as a single phenomenon in animals and plants, as in these organisms reproduction implies mixis and meiosis. In contrast, sex and reproduction are independent biological phenomena that may or may not be linked in the majority of other eukaryotes. Current evidence supports a eukaryotic ancestor bearing a mating type

A contribution to the phylogeny of agglutinating Arcellinida (Amoebozoa) based on SSU rRNA gene sequences [PDF]
, 2017 Arcellinid testate amoebae include a wide variety of amoeboid organisms whose test (shell) varies in shape, composition and size. A decade ago, we initiated molecular phylogenetic analyses based on SSU rRNA gene sequences and a taxonomic revision of ...

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.

The evolutionary history of histone H3 suggests a deep eukaryotic root of chromatin modifying mechanisms [PDF]
, 2010 Background The phenotype of an organism is an outcome of both its genotype, encoding the primary sequence of proteins, and the developmental orchestration of gene expression.

Environmental DNA COI barcoding for quantitative analysis of protists communities: A test using the Nebela collaris complex (Amoebozoa;Arcellinida; Hyalospheniidae) [PDF]
, 2015 Environmental DNA surveys are used for screening eukaryotic diversity. However, it is unclear how quantitative this approach is and to what extent results from environmental DNA studies can be used for ecological studies requiring quantitative data ...

The largest reservoir of mitochondrial introns is a relic of an ancestral split gene [PDF]
, 2010 In eukaryotes, introns are located in nuclear and organelle genes from several kingdoms (ref. 1-4). Large introns (0.1 to 5 kbp) are frequent in mitochondrial genomes of plant and fungi (ref.
