Interactions between cytoplasmic (generally organelle) and nuclear genomes may be relatively common and could potentially have major fitness consequences. As in the case of within-genome epistasis, this cytonuclear epistasis can favor the evolutionary coadaptation of high-fitness combinations of nuclear and cytoplasmic alleles. Because cytoplasmic factors are generally uniparentally inherited, the cytoplasmic genome is inherited along with only one of the nuclear haplotypes, and therefore…

TLDR
It is demonstrated theoretically that the presence of gene interactions that favor coadaptation can also favor the evolution of genomic imprinting, an epigenetic phenomenon in which the expression of a gene copy inherited from the mother differs from that of the copy inherit from the father.
Gene interactions in the evolution of genomic imprinting
TLDR
A subset of theories wherein non-additive genetic interactions can favour imprinting is explored, and key links and differences using a unified framework are illustrated and explored.
Update on Plant Gene Imprinting Endosperm and Imprinting , Inextricably Linked 1 [ OPEN ]
The endosperm is often viewed as a complicated and rather strange tissue: its genome is triploid, it is formed from a second fertilization event specific to flowering plants, and it is a frequent
Cytoplasmic genetic variation and extensive cytonuclear interactions influence natural variation in the metabolome
TLDR
A metabolomic QTL analysis on a reciprocal RIL population structured to examine how variation in the organelle genomes affects phenotypic variation showed that the cytoplasmic variation had effects similar to, if not larger than, the largest individual nuclear locus.
Cytonuclear Evolution of Rubisco in Four Allopolyploid Lineages
TLDR
It is demonstrated that paralogous nuclear-encoded rbcS genes within diploids are subject to homogenization via gene conversion and that such concerted evolution via gene Conversion characterizes duplicated genes (homoeologs) at the polyploid level.
The cytonuclear dimension of allopolyploid evolution: an example from cotton using rubisco.
TLDR
Sequence data for the rbcS gene family revealed nonreciprocal homoeologous recombination in all polyploid species but not in a synthetic intergenomic F1 hybrid, demonstrating "gene conversion" during allopolyploid evolution.
Cytonuclear Variation of Rubisco in Synthesized Rice Hybrids and Allotetraploids
TLDR
It was concluded that cytonuclear coordination in the present rice case either is not selectively favored because of high parental sequence similarity, or that there has been insufficient time for subtle selective effects to become observable.

TLDR
Results show that the transient increment in F(st) for a neutral allele is not only related to the vectors of seed and pollen dispersal but also to the mode of its inheritance, and the roles of transient cytonuclear disequilibrium as a biological factor in evolving population differentiation are highlighted.
The maternal cytoplasmic environment may be involved in the viability selection of gametes and zygotes
TLDR
Results suggested that selfish cytoplasmic elements may have an important role in shaping the patterns of segregation distortion in F2 populations through selective viability of gametes and zygotes.
Analysis of genomic imprinting by quantitative allele-specific expression by Pyrosequencing(®).
TLDR
This chapter describes the use of Quantification of Allele-Specific Expression by Pyrosequencing(®) (QUASEP) as a tool suitable for this challenge and provides a brief overview of the future possibility of adapting Pyrosequenced genes for analyzing other aspects of imprinting including the analysis of methylated regions.

Intergenomic Epistasis for Fitness: Within-Population Interactions Between Cytoplasmic and Nuclear Genes in Drosophila melanogaster
TLDR
This work experimentally tested for cytonuclear interactions within a laboratory population of Drosophila melanogaster using 25 randomly sampled cytoplasmic genomes, expressed in three different haploid nuclear genetic backgrounds, while eliminating confounding effects of intracellular bacteria.

TLDR
The possibility that adaptive cytoplasmic elements, such as favorable mitochondrial mutations or endosymbionts, have the potential to release heritable nuclear variation as they sweep through a host population, supporting the view that cytop lasmic introgression plays an important role in adaptation and speciation.
Sexually antagonistic cytonuclear fitness interactions in Drosophila melanogaster.
TLDR
A model of joint transmission of X chromosomes and cytoplasms is developed and through simulation show that nuclear-cytoplasmic polymorphisms can be maintained by selection on X-cyoplasm interactions, and results suggest that fitness interactions with the sex chromosomes may account for some proportion of cytopLasmic variation in natural populations.
Consequences of cytonuclear epistasis and assortative mating for the genetic structure of hybrid populations
TLDR
It appears that the combined action of epistasis and assortative mating would be sufficient to maintain the high levels of cytonuclear disequilibria observed.
A Maternal–Offspring Coadaptation Theory for the Evolution of Genomic Imprinting
TLDR
It is demonstrated that sole expression of maternal gene copies is favored by natural selection because it increases the adaptive integration of offspring and maternal genomes, leading to higher offspring fitness.
Associations between cytoplasmic and nuclear Loci in hybridizing populations.
TLDR
The general framework developed here allows us to investigate conditions where associations between loci with different modes of inheritance are not equivalent and to use this nonequivalence to test for deviations from simple models of admixture.
EPISTATIC AND CYTONUCLEAR INTERACTIONS GOVERN OUTBREEDING DEPRESSION IN THE AUTOTETRAPLOID CAMPANULASTRUM AMERICANUM
TLDR
This study, the first of its kind on a natural autotetraploid, suggests that gene duplication may cause polyploid populations to diverge in a fundamentally different way than diploids.
Cytonuclear coevolution: the genomics of cooperation.
TLDR
The goals are to clarify the coevolutionary events that have governed nuclear and organelle evolution, and to encourage further critical analyses of these interactions as problems in the study of co-adapted gene complexes.
GENE INTERACTIONS FROM MATERNAL EFFECTS

TLDR
The among‐genotype epistasis resulting from parental effects may contribute to ruggedness of adaptive landscapesBecause early mortality often accounts for much of the variance in fitness in populations, the relationship between the evolutionary dynamics resulting from these two forms of epistasis is discussed.

TLDR
This study shows that epistatic interactions between cytochrome c (CYC) alleles and mitochondrial DNA (mtDNA) variation are dramatically influenced by environmental temperature in interpopulation hybrids of the copepod Tigriopus californicus, and indicates that the fitness of particular hybrid genotypes depends on additional non‐mtDNA encoded genes that interact with CYC.
