Sexual reproduction in eukaryotes is accomplished by meiosis, a complex and specialized process of cell division that results in haploid cells (e.g., gametes). The stereotypical reductive division in meiosis is a major evolutionary innovation in eukaryotic cells, and delineating its history is key to understanding the evolution of sex. Meiosis arose early in eukaryotic evolution, but when and how meiosis arose and whether all eukaryotes have meiosis remain open questions. The known phylogenetic… Expand
An Expanded Inventory of Conserved Meiotic Genes Provides Evidence for Sex in Trichomonas vaginalis
TLDR
The analyses indicate that these meiotic genes arose, or were already present, early in eukaryotic evolution; thus, the eUKaryotic cenancestor contained most or all components of this set and was likely capable of performing meiotic recombination using near-universal meiotic machinery. Expand
Comparative Genomics Supports Sex and Meiosis in Diverse Amoebozoa
TLDR
It is concluded that most amoebozoans may perform mixis, recombination, and ploidy reduction through canonical meiotic processes, which indicates the possibility of sexual cycles in many lineages traditionally held as asexual. Expand
Identification of the meiotic toolkit in diatoms and exploration of meiosis-specific SPO11 and RAD51 homologs in the sexual species Pseudo-nitzschia multistriata and Seminavis robusta
TLDR
The results reveal the conserved meiotic toolkit in six diatom species and indicate that Stramenopiles share major modifications of canonical meiosis processes ancestral to eukaryotes, with important divergences in each Kingdom. Expand
Protist homologs of the meiotic Spo11 gene and topoisomerase VI reveal an evolutionary history of gene duplication and lineage-specific loss.
TLDR
The phylogenetic analyses show that Spo11 homologs evolved by two ancient eukaryotic gene duplication events prior to the last common ancestor of extant eUKaryotes, resulting in three eucaryotic paralogs: Spo11-1, Spo11 -2, and Spo 11-3. Expand

TLDR
A "meiosis detection toolkit", a set of meiotic genes that represent the best markers for the presence of meiosis that will help to understand both meiotic gene evolution and the capacity for meiosis and sex in putative obligate asexuals. Expand
All Eukaryotes Are Sexual, unless Proven Otherwise

  • 2019
TLDR
A wide distribution of meiotic machinery is shown, indicating the occurrence of sexual processes in all major eukaryotic groups, without exceptions, including the putative “asexuals,” as well as presumed asexuality correlates with lack of study. Expand
The evolution of meiotic sex and its alternatives
TLDR
This overview suggests that homologue pairing, double-strand break formation and homologous recombinational repair at prophase I are the least dispensable elements, and they are more likely optimized for repair of oxidative DNA damage rather than for recombination. Expand
Sexual Processes in Microbial Eukaryotes
TLDR
Parts of the sexual processes of a number of well-studied microbial eukaryotes are indicated that support the idea that meiosis is primarily a process for repairing DNA. Expand
Evolutionary Origin of Recombination during Meiosis
TLDR
If continuity of selection through the prokaryote to eukaryote transition probably would have followed a course in which bacterial transformation naturally gave rise to the recombination process that is central to eUKaryote meiosis, then these processes are adaptations for dealing with stress. Expand
Differential gene expression analysis and cytological evidence reveal a sexual stage of an amoeba with multiparental cellular and nuclear fusion
TLDR
This study provides strong evidence that the fused cells represent a sexual stage in Cochliopodium, and has further implications in understanding the evolution and mechanism of inheritance involving multiparents in other eukaryotes with a similar reproductive strategy. Expand

A review and classification of the predicted effects of loss of sex on the eukaryotic genome is presented and the utility of the various predictions for detecting ancient asexuality, for testing hypotheses of the reversibility of a transition to a sexual phase, and for discriminating between theories of sex is discussed.

Origins of the machinery of recombination and sex
TLDR
The dominant selective force in the evolution of recombination and sex has been selection for replicational fidelity and viability; without the recombination machinery, accurate reproduction, stasis, resistance to radical deleterious evolutionary change and preservation of evolutionary innovations would be impossible.

TLDR
The remarkable biparental inheritance of organelle DNA (=kinetoplast DNA) in T. brucei is without precedent in other eukaryotes, and a possible role for genetic exchange in enhancing the diversity of the repertoire is suggested. Expand
The First Sexual Lineage and the Relevance of Facultative Sex
TLDR
A maximum-likelihood analysis of elongation factor-1α sequences shows that the parabasalids diverged prior to the oxymonads and thus represent the earliest sexual lineage of eukaryotes, and has important implications for the ``Best-Man hypothesis'' and other models for the origin of sex. Expand

TLDR
The entire genome of this protozoan Giardia lamblia, one of the earliest-branching eukaryotes, contains only retrotransposons that are either confined to telomeric regions and possibly beneficial, or inactivated and completely nonfunctional. Expand
Microsporidia are related to Fungi: evidence from the largest subunit of RNA polymerase II and other proteins.
TLDR
Phylogenetic analyses of RPB1 sequences strongly support the notion that Microsporidia are not early-diverging eukaryotes but instead are specifically related to Fungi, and reexamination of elongation factors EF-1alpha and EF-2 sequence data show support for an early (Archezoan) divergence of these amitochondriate protists to be weak and likely caused by artifacts in phylogenetic analyses.

TLDR
The nuclear and cellular genome ploidy of G. lamblia cells during all stages of the life cycle is determined and it is suggested that the newly excysted cell, for which the term ‘excyzoite’ is suggested, contains four nuclei. Expand
