Recent evidence indicates that meiosis arose very early in eukaryotic evolution, which suggests that essential features of meiosis were already present in the prokaryotic ancestors of eukaryotes. Furthermore, in extant organisms, proteins with central functions in meiosis are similar in sequence and function to key proteins in bacterial transformation. In particular, RecA recombinase—which performs the central functions of DNA homology search and strand exchange in bacterial transformation—has… Expand
Sexual Communication in Archaea, the Precursor to Eukaryotic Meiosis
TLDR
Evidence is presented that archaeal mating was the likely ancestral precursor to eukaryotic meiotic sex, and evolution in complexity was likely part of a general protective response to DNA damaging reactive oxygen species produced by the proto-mitochondria during the prokaryotic to eUKaryotic transition. Expand
Evolutionary Origin and Adaptive Function of Meiosis
TLDR
Accumulating evidence indicates that meiosis arose very early in the evolution of eukaryotes, and basic features of meiosis were likely already present in the prokaryotic ancestors of eUKaryotes. Expand
Chapter 3 Evolutionary Origin and Adaptive Function of Meiosis
The origin of meiosis and its adaptive function in eukaryotes, and the related problem of the origin and adaptive function of sex in eukaryotes, are fundamental issues in biology. Among eukaryotes,Expand
Meiosis as an Evolutionary Adaptation for DNA Repair
TLDR
Evidence that meiosis is primarily an evolutionary adaptation for DNA repair is presented, including evidence that among microbial pathogens, sexual processes promote repair of DNA damage, especially when challenged by the oxidative defenses of their biologic hosts. Expand
Genetic recombinational events in prokaryotes and their viruses: insight into the study of evolution and biodiversity
  • J. Gratia
  • Biology, Medicine
  • Antonie van Leeuwenhoek
  • 2017
TLDR
The present review aims at highlighting the diversity of mechanisms with a particular focus on spontaneous zygogenesis (or Z-mating), which was recently discovered in Escherichia coli and resembles gamete fusion in eukaryotes in that it involves complete genetic mixing. Expand
Have Sex or Not? Lessons from Bacteria
  • T. Lodé
  • Medicine, Biology
  • Sexual Development
  • 2012
TLDR
Rather than providing selective advantages through reproduction, sex could be thought of as a series of separate events which combines step-by-step some very weak benefits of recombination, meiosis, gametogenesis and syngamy. Expand
Recombination as a driver of genome evolution : characterisation of biased gene conversion in mice
TLDR
These findings are consistent with the hypothesis of a selective pressure restraining the intensity of the deleterious gBGC process at the population-scale: this would materialise through a multi-level compensation of the effective population size by the recombination rate, the length of conversion tracts and the transmission bias. Expand
Meiosis, Balbiani body and early asymmetry of Thermobia oocyte
TLDR
Following the course of initial stages of meiotic division in ovaries of Thermobia domestica using modified techniques of squash preparations, semithin sections, and electron microscopy, it is shown that germaria contain numerous germline cells that can be classified into three categories: cystoblasts, meiotic oocytes, and growing previtellogenic oocytes.

The effect of different genome and cytoplasm on meiotic pairing in maize newly synthetic polyploids
TLDR
In the four neoallopolyploids, the stability of maize genome is consistently lower than that of Z. perennis genome and the cytoplasm, genome composition and their interaction do have the special role in chromosome paring and the meiosis behaviors in Zea allopolyploid vary significantly and showed non-diploidization.

Neoplastic-Like CELL Changes of Normal Fibroblast Cells Associated with Evolutionary Conserved Maternal and Paternal Genomic Autonomous Behavior (Gonomery)
TLDR
The modern genome of man harbors, relic-genetics from past “good” evolvements assuring “stable” proliferation of ancient, primitive eukaryotes, but with cancer-like effects for normal human cells. Expand

A Phylogenomic Inventory of Meiotic Genes Evidence for Sex in Giardia and an Early Eukaryotic Origin of Meiosis
TLDR
The presence of five meiosis-specific genes indicates that Giardia is capable of meiotic and, thus, sexual reproduction, and the evolution of meiosis occurred early in eukaryotic evolution. 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
Mechanism of eukaryotic homologous recombination.
TLDR
HR accessory factors that facilitate other stages of the Rad51- and Dmc1-catalyzed homologous DNA pairing and strand exchange reaction have also been identified. Expand
The Arabidopsis AtRAD51 gene is dispensable for vegetative development but required for meiosis.
TLDR
It is suggested that RAD51 function is essential for chromosome pairing and synapsis at early stages in meiosis in Arabidopsis, and major aspects of meiotic recombination seem to be conserved between yeast and plants, especially the fact that chromosome Pairing and Synapsis depend on the function of SPO11 and RAD51.

The RecA protein as a recombinational repair system
  • M. Cox
  • Biology, Medicine
  • Molecular microbiology
  • 1991
TLDR
This work has shown that filamentous protein structures involving thousands of RecA monomers, which hydrolyse 100 ATPs per base pair of heteroduplex DNA formed, are hard to rationalize in the context of recombination between two homologous DNAs. Expand
The archaebacterial origin of eukaryotes
TLDR
The analyses favor a topology that supports the eocyte hypothesis rather than archaebacterial monophyly and the 3-domains tree of life, which is thought to be central to understanding the evolution of the eukaryotic cell. Expand
A New Aspect to the Origin and Evolution of Eukaryotes
TLDR
This paper suggests, based on the energetic aspect of genome organization, that the emergence of eukaryotes was promoted by the establishment of an efficient energy-converting organelle, such as the mitochondrion, which was acquired by the endosymbiosis of ancient α-purple photosynthetic Gram-negative eubacteria that reorganized the prokaryotic metabolism of the archaebacterial-like ancestral host cells. Expand
Mitochondrial evolution.
TLDR
Gene sequence data strongly support a monophyletic origin of the mitochondrion from a eubacterial ancestor shared with a subgroup of the alpha-Proteobacteria and raise the possibility that this organelle originated at essentially the same time as the nuclear component of the eukaryotic cell rather than in a separate, subsequent event. Expand
Mitochondrial evolution : Mitochondria
TLDR
Gene sequence data strongly support a monophyletic origin of the mitochondrion from a eubacterial ancestor shared with a subgroup of the α-Proteobacteria and raise the possibility that this organelle originated at essentially the same time as the nuclear component of the eukaryotic cell rather than in a separate, subsequent event.

Structural relationship of bacterial RecA proteins to recombination proteins from bacteriophage T4 and yeast.
TLDR
Analysis of the primary sequence relationships of DMC1 from Saccharomyces cerevisiae and UvsX of T4 relative to the three-dimensional structure of RecA from Escherichia coli suggests that both proteins are structural homologs of bacterial RecA proteins. Expand
