Abstract:
The mitonuclear genome is the most successful co-evolved mutualism in the history of life on Earth. The cross-talk between the mitochondrial and nuclear genomes has been shaped by conflict and cooperation for more than 1.5 billion years, yet this system has adapted to countless genomic reorganizations by each partner, and done so under changing environments that have placed dramatic biochemical and physiological pressures on evolving lineages. From putative anaerobic origins, mitochondria emerged as the defining aerobic organelle. During this transition, the two genomes resolved rules for sex determination and transmission that made uniparental inheritance the dominant, but not a universal pattern. Mitochondria are much more than energy-producing organelles and play crucial roles in nutrient and stress signalling that can alter how nuclear genes are expressed as phenotypes. All of these interactions are examples of genotype-by-environment (GxE) interactions, gene-by-gene (GxG) interactions (epistasis) or more generally context-dependent effects on the link between genotype and phenotype. We provide evidence from our own studies in Drosophila , and from those of other systems, that mitonuclear interactions—either conflicting or cooperative—are common features of GxE and GxG. We argue that mitonuclear interactions are an important model for how to better understand the pervasive context-dependent effects underlying the architecture of complex phenotypes. Future research in this area should focus on the quantitative genetic concept of effect size to place mitochondrial links to phenotype in a proper context. This article is part of the theme issue ‘Linking the mitochondrial genotype to phenotype: a complex endeavour’.

Abstract:
Abstract Eukaryotes are the outcome of an ancient symbiosis and as such, eukaryotic cells fundamentally possess two genomes. As a consequence, gene products encoded by both nuclear and mitochondrial genomes must interact in an intimate and precise fashion to enable aerobic respiration in eukaryotes. This genomic architecture of eukaryotes is proposed to necessitate perpetual coevolution between the nuclear and mitochondrial genomes to maintain coadaptation, but the presence of two genomes also creates the opportunity for intracellular conflict. In the collection of papers that constitute this symposium volume, scientists working in diverse organismal systems spanning vast biological scales address emerging topics in integrative, comparative biology in light of mitonuclear interactions.

Abstract:
By far, the interordinal relationships in rosids remain poorly resolved. Previous studies based on chloroplast, mitochondrial, and nuclear DNA has produced conflicting phylogenetic resolutions that has become a widely concerned problem in recent phylogenetic studies. Here, a total of 96 single-copy nuclear gene loci were identified from the KOG (eukaryotic orthologous groups) database, most of which were first used for phylogenetic analysis of angiosperms. The orthologous sequence datasets from completely sequenced genomes of rosids were assembled for the resolution of the position of the COM (Celastrales–Oxalidales–Malpighiales) clade in rosids. Our analysis revealed strong and consistent support for CM topology (the COM clade as sister to the malvids). Our results will contribute to further exploring the underlying cause of conflict between chloroplast, mitochondrial, and nuclear data. In addition, our study identified a few novel nuclear molecular markers with potential to investigate the deep phylogenetic relationship of plants or other eukaryotic taxonomical groups.

Abstract:
The mitochondrial genome is an evolutionarily persistent and cooperative component of metazoan cells that contributes to energy production and many other cellular processes. Despite sharing the same host as the nuclear genome, the multi-copy mitochondrial DNA (mtDNA) follows very different rules of replication and transmission, which translate into differences in the patterns of selection. On one hand, mtDNA is dependent on the host for its transmission, so selections would favour genomes that boost organismal fitness. On the other hand, genetic heterogeneity within an individual allows different mitochondrial genomes to compete for transmission. This intra-organismal competition could select for the best replicator, which does not necessarily give the fittest organisms, resulting in mito-nuclear conflict. In this review, we discuss the recent advances in our understanding of the mechanisms and opposing forces governing mtDNA transmission and selection in bilaterians, and what the implications of these are for mtDNA evolution and mitochondrial replacement therapy.

Abstract:
A preliminary phylogenetic analysis involving 22 taxa of the genus Isophya was conducted using four molecular markers (sequences of mitochondrial cytochrome b (cyt b), fragments of mitochondrial cytochrome oxidase subunit II (COII) and the internal transcribed spacers I and II (ITS1 and ITS2)). Our results indicate that Isophya is a monophyletic group with the exception of one species, I. bivittata. The analysis revealed a high level of polymorphism in the mitochondrial and nuclear genes of all species. MtDNA performs better in the phylogenetic reconstruction of Isophya than the ITS markers. Although the results show some conflict with the systematics of the group known from morphological and bioacoustic data, the study can be the basis for future reconstructions of the phylogeny of Isophya.

Abstract:
AbstractWe reconstructed a phylogeny for the seven species of doves in the genus Zenaida on the basis of a combined analysis of mitochondrial (ND2 and cytochrome b) and nuclear (fibrinogen intron 7) DNA sequences. This phylogeny, which is completely resolved, is well supported with all nodes showing greater than 50% bootstrap support. There was no significant conflict between trees based on each gene independently, although trees produced from fibrinogen intron 7 did not resolve relationships among five of the Zenaida species. The species status of Z. graysoni, as well as that of Z. meloda, is suggested based on their divergence from sister taxa (about 1% and 4%, respectively) and other differences. Zenaida can be divided into two major groups: Zenaida asiatica and Z. meloda versus Z. aurita, Z. galapagoensis, Z. auriculata, Z. graysoni, and Z. macroura.

Abstract:
Despite multiple attempts to infer the higher-level phylogenetic relationships of skipper butterflies (Family Hesperiidae), uncertainties in the deep clade relationships persist. The most recent phylogenetic analysis included fewer than 30% of known genera and data from three gene markers. Here we reconstruct the higher-level relationships with a rich sampling of ten nuclear and mitochondrial markers (7,726 bp) from 270 genera and find two distinct but equally plausible topologies among subfamilies at the base of the tree. In one set of analyses, the nuclear markers suggest two contrasting topologies, one of which is supported by the mitochondrial dataset. However, another set of analyses suggests mito-nuclear conflict as the reason for topological incongruence. Neither topology is strongly supported, and we conclude that there is insufficient phylogenetic evidence in the molecular dataset to resolve these relationships. Nevertheless, taking morphological characters into consideration, we suggest that one of the topologies is more likely.

Abstract:
Advancements in molecular sequencing have revealed unexpected cryptic genetic diversity and contrasting evolutionary histories within genes and between genomes of many organisms; often in disagreement with recognized taxonomy. Incongruent patterns between the mitochondrial and nuclear evolutionary history can have several plausible explanations, but widespread systematic conflict inevitably challenges our conceptions of species boundaries when there is discordance between coevolving and coinherited genomes. It is unknown to what degree mitonuclear conflict drives the process of divergence, or how ubiquitous these patterns are across the tree of life. To understand the evolutionary relevance of intergenomic discordance we must identify the conflicting patterns that exist in natural systems by generating robust estimates of the underlying species history, quantify support for alternative hypotheses of lineage formation, and describe patterns of genetic variation present in robust nuclear genomic datasets. Empirically testing correlations between mitonuclear genomic conflict and reduced gene flow at the organism level will contribute toward a better understanding of lineage boundaries and how intergenomic interactions shape the process of divergence. Mitochondrial introgression has been inferred in many salamander systems with limited perspective from nuclear sequence data. Within dusky salamanders (Desmognathus), these patterns have been observed between morphologically and geographically disparate populations. I sequenced regions throughout the nuclear genome to reconstruct species trees, performed population-level analyses testing concordance between the mitochondrial, nuclear datasets, and nuclear genes with mitochondrial functions with the expectation that coevolutionary interactions among genomes are more likely to manifest in these regions. I also estimated migration rates between populations that may have experienced historical mitochondrial introgression to evaluate phylogeographic patterns. Using these data we definitively reject species models in which genetic boundaries are based solely on mitochondrial data, favoring geographic models instead. Furthermore, analyses soundly reject current taxonomic models based on morphological characteristics, suggesting there is greater lineage diversity than is currently recognized. I also used empirical assays of pre-zygotic reproductive mating behavior within and among populations containing diverse mitochondrial lineages to test metrics of reproductive isolation, and to determine if introgression shapes the evolution of complex traits directly influencing rates of divergence. These results may explain incongruent patterns observed between the mitochondrial and nuclear data as a function of inheritance and population dynamics rather than directly functioning to suppress nuclear gene flow. This research builds upon recent studies suggesting that speciation is a highly complex and often non-bifurcating process in which introgression can have a profound and lasting signature on the nuclear evolutionary history. Mechanisms responsible for divergence with gene flow challenge evolutionary biologists to reevaluate our notions and definitions of species boundaries to accommodate seemingly conflicted genomic patterns within and between genomes.

Abstract:
Eukaryotes were born of a chimeric union of two prokaryotes. The legacy of this fusion is organisms with both a nuclear and mitochondrial genome that must work in a coordinated fashion to enable cellular respiration. The coexistence of two genomes in a single organism requires tight coadaptation to enable function. The need for coadaptation, the challenge of co-transmission, and the possibility of genomic conflict between mitochondrial and nuclear genes have profound consequences for the ecology and evolution of eukaryotic life. This book defines mitonuclear ecology as an emerging field that reassesses core concepts in evolutionary ecology in light of the necessity of mitonuclear coadaptation. I discuss and summarize research that tests new mitonuclear-based theories for the evolution of sex, two sexes, senescence, a sequestered germ line, speciation, sexual selection, and adaptation. The ideas presented in this book represent a paradigm shift for evolutionary ecology. Through the twentieth century, mitochondrial genomes were dismissed as unimportant to the evolution of complex life because variation within mitochondrial genomes was proposed to be functionally neutral. These conceptions about mitochondrial genomes and mitonuclear genomic interactions have been changing rapidly, and a growing literature in top journals is making it increasingly clear that the interactions of the mitochondrial and nuclear genomes over the past 2 billion years have played a major role in shaping the evolution of eukaryotes. These new hypotheses for the evolution of quintessential characteristics of complex life hold the potential to fundamentally reshape the field of evolutionary ecology and to inform the emerging fields of mitochondrial medicine and mitochondrial-based reproductive therapies.

Abstract:
Mitochondrial genes and nuclear genes are replicated and transmitted across generations as physically separated units. The extent to which these autonomous genomes are co-transmitted depends on the position of nuclear genes on autosomes versus sex chromosomes, and co-transmission has important implications for mitonuclear coevolution and conflict. Mitonuclear co-transmission, coadaptation, and coevolution are potentially very important for understanding fundamental evolutionary phenomena like Haldane’s rule. In addition, because mitochondrial genomes are transmitted strictly through maternal lines in most eukaryotes, selection on mitochondrial genes can favor female fitness over male fitness, leading to mother’s curse. The chapter assesses and draws conclusions about the relative importance of mitonuclear coadaptation and conflict in the evolution of eukaryotic lineages.
