Molecular evolution: Sex accelerates adaptation

  title={Molecular evolution: Sex accelerates adaptation},
  author={Matthew R. Goddard},
An analysis confirms the long-standing theory that sex increases the rate of adaptive evolution by accelerating the speed at which beneficial mutations sweep through sexual, as opposed to asexual, populations. See Letter p.233 Explaining the prevalence of sexual reproduction despite its costly nature is a famously long-standing question in evolutionary biology. Theory and some experimental studies suggest various mechanisms responsible, such as a reduction in clonal interference or the ability… Expand

Sex and recombination purge the genome of deleterious alleles: An Individual Based Modeling Approach
The purifying selection hypothesis, the hypothesis that recombination due to sexual reproduction helps to eliminate deleterious alleles from the genome through the selection of reduced function mutations, is corroborated. Expand
The Genome of the Human Pathogen Candida albicans Is Shaped by Mutation and Cryptic Sexual Recombination
An analysis of heterozygous diploid genomes from 21 clinical isolates is performed to determine the natural evolutionary processes acting on the C. albicans genome, establishing that both (para)sexual recombination and mitotic mutational processes drive evolution of this important pathogen. Expand
The Genome of the Human Pathogen Candida albicans is Shaped by Mutation and Cryptic Sexual Recombination
It is established that the C. albicans genome evolves by a combination of base-substitution mutations, insertions/deletion events, and both short-tract and long-Tract loss of heterozygosity (LOH) events, which are unevenly distributed across the genome. Expand
A ‘parameiosis’ drives depolyploidization and homologous recombination in Candida albicans
Results indicate that C. albicans CCL represents a ‘parameiosis’ that blurs the conventional boundaries between mitosis and meiosis and reveal parallels with depolyploidization in mammalian cells and provide potential insights into the evolution of meiosis. Expand
Enlarge or die! An auxospore perspective on diatom diversification
It is argued that combined with the widely varying but taxon-specific aspects of diatom gametogenetic processes, auxospores are excellent tools for cross group comparisons that provide insight into their evolutionary relationships. Expand
Saccharomyces cerevisiae metabolism in ecological context
A brief review of the genotypic and phenotypic peculiarities of S. cerevisiae in the context of its social lifestyle beyond laboratory environments is presented. Expand
Fungal Sex: The Ascomycota.
What is known about sexual fecundity in ascomycetes is summarized, how structural changes at the mating-type locus dictate sexual behavior is examined, and recent studies that reveal that pheromone signaling pathways can be repurposed to serve cellular roles unrelated to sex are discussed. Expand
Metabolism‐induced oxidative stress and DNA damage selectively trigger genome instability in polyploid fungal cells
It is revealed how endogenous metabolic processes can generate sufficient ROS to trigger genome instability in polyploid C. albicans cells and speculated that ROS‐induced DNA damage could have facilitated ploidy cycling prior to a conventional meiosis in eukaryotes. Expand
Metabolism-Induced Oxidative Stress and DNA Damage Selectively Trigger Genome Instability in Polyploid Cells
It is proposed that ROS-induced DNA damage could have facilitated ploidy cycling in eukaryotes prior to the evolution of meiosis, and how metabolic flux can generate endogenous ROS, triggering DNA damage and genome instability in polyploids, but not diploid, cells is revealed. Expand
ISSR markers for gender identification and genetic diagnosis of Hippophae rhamnoides ssp. turkestanica growing at high altitudes in Ladakh region (Jammu and Kashmir)
The results confirmed sex-linked specificity of the marker suggesting that this conserved sequence at the Y chromosome is well preserved through the populations in Ladakh region and shall provide a reliable molecular tool for early identification of the sex in this commercial crop. Expand


Sex Speeds Adaptation by Altering the Dynamics of Molecular Evolution
It is demonstrated that sex both speeds adaptation and alters its molecular signature by allowing natural selection to more efficiently sort beneficial from deleterious mutations. Expand
Sex releases the speed limit on evolution
It is shown that sex can increase the rate of adaptation in the facultatively sexual single-celled chlorophyte Chlamydomonas reinhardtii, but that the benefits of sex depend crucially on the size of the population that is adapting: sex has a marked effect in large populations but little effect in small populations. Expand
Sex enhances adaptation by unlinking beneficial from detrimental mutations in experimental yeast populations
Sex appeared to facilitate adaptation not just by more rapidly combining beneficial mutations, but also by unlinking beneficial from detrimental mutations: sex allowed selection to operate on both types of mutations more effectively compared to asexual populations. Expand
Sex increases the efficacy of natural selection in experimental yeast populations
It is shown that, as predicted by the theory, sex increases the rate of adaptation to a new harsh environment but has no measurable effect on fitness in a new benign environment where there is little selection. Expand
Gene-flow between niches facilitates local adaptation in sexual populations.
The effect of sex in heterogeneous environments is evaluated by manipulating gene-flow between two niches in sexual and asexual populations using steady-state microcosm experiments with yeast to find that only sex in the presence of gene- flow promotes simultaneous local adaptation to different niches.

This study presents a mathematical model in which a single beneficial mutation arises in a very large population that is subject to frequent deleterious mutations. The results suggest that, if theExpand
A parasitic selfish gene that affects host promiscuity
The data presented here show a selfish element may increase the propensity of its eukaryote host to undergo sex and along with increased rates of non-Mendelian inheritance, this may counterbalance mitotic selective load and promote spread. Expand

Although Weismann's hypothesis must be considered the leading candidate for the function of sex and recombination, nevertheless, many additional principles are needed to fully account for their evolution. Expand
Running with the Red Queen: Host-Parasite Coevolution Selects for Biparental Sex
It is found that coevolution with a bacterial pathogen resulted in significantly more outcrossing in mixed mating experimental populations of the nematode Caenorhabditis elegans, consistent with the Red Queen hypothesis, and coevolving pathogens can select for biparental sex. Expand
Some Genetic Aspects of Sex
