Cytoplasmic male sterility (CMS) in plants is a classical example of genomic conflict, opposing maternally-inherited cytoplasmic genes (mitochondrial genes in most cases), which induce male sterility, and nuclear genes, which restore male fertility. In natural populations, this type of sex control leads to gynodioecy, that is, the co-occurrence of female and hermaphroditic individuals within a population. According to theoretical models, two conditions may maintain male sterility in a natural… 
Did doubly uniparental inheritance (DUI) of mtDNA originate as a cytoplasmic male sterility (CMS) system?
TLDR
It is hypothesize that the only exception to the strict maternal mtDNA inheritance in animals, the doubly uniparental inheritance (DUI) system in bivalves, might have originated as a mitochondrial‐nuclear sex‐determination system.
A Cryptic Cytoplasmic Male Sterility Unveils a Possible Gynodioecious Past for Arabidopsis thaliana
TLDR
The results suggest that this CMS system induced sexual polymorphism in A. thaliana populations, at the time when the species was mainly outcrossing, as well as the coexistence of the sterilizing cytoplasm with a non-sterilizing cy toplasm in a natural population.
Paternal Leakage Sustains the Cytoplasmic Polymorphism Underlying Gynodioecy but Remains Invasible by Nuclear Restorers
TLDR
It is shown that even a small amount of paternal leakage is sufficient to sustain a permanent, stable cytoplasmic polymorphism and enhances the stability of joint cytonuclear polymorphism.
Genetic and molecular basis of cytoplasmic male sterility in maize
TLDR
In maize three types of CMS systems, namely CMS-T, CMS-S and CMS-C, have been documented and are differentiated by the reaction to restorers, mitochondrial DNA restriction digest patterns, and complements of low molecular weight plasmids.

Modelling the maintenance of male-fertile cytoplasm in a gynodioecious population
TLDR
A model to investigate the conditions that promote the maintenance of this breeding system in the case of an outcrossed species when CMS and male-fertile (non-CMS) cytotypes are present in an infinite panmictic population shows that gynodioecy was attainable for a large set of parameter values, including low differences in fitness among genotypes and phenotypes.
Migration Restores Hybrid Incompatibility Driven By Mitochondrial-Nuclear Sexual Conflict
TLDR
The results show that these interactions may act as Dobzhansky–Muller incompatibilities, but their strength is not enough to drive population isolation, which shows the varied ways in which populations can respond to migration’s disruption of co-evolved mitochondrial-nuclear interactions.
The Propensity of Pentatricopeptide Repeat Genes to Evolve into Restorers of Cytoplasmic Male Sterility
TLDR
PPR proteins represent the most frequent protein class among identified Rfs and they exhibit ideal characteristics to evolve into restorer of fertility when the mechanism of restoration implies a post-transcriptional action.

No evidence for local adaptation between cytoplasmic male sterility and nuclear restorer genes in the gynodioecious species Thymus vulgaris L.
TLDR
It is suggested that the same evolutionary processes giving rise to individual differences among cytoplasmic male-sterility types might account for the absence of local adaptation between nuclear and cytopLasmic factors in this system, and the absence in the light of a recent model of local adaptations in host-parasite metapopulations is discussed.

TLDR
A striking difference was observed between the potential genetic control of male sterility built into the simulation model, which reflects assumptions about the underlying physiological mechanisms of normal and aberrant pollen production, and the types of genetic control that would be inferred by performing classical genetic crossing experiments on a sample of the simulated population.
Nuclear-Cytoplasmic Male Sterility: Single-Point Equilibria Versus Limit Cycles
TLDR
The limit-cycle phenomenon may explain the negative correlation between the two cytoplasmic male-sterility types found in Plantago lanceolata and, more generally, any interpopulation variation inmale-sterile frequencies, without invoking any ecological cause.
A pentatricopeptide repeat-containing gene restores fertility to cytoplasmic male-sterile plants
TLDR
The isolation of a gene directly involved in the control of the expression of a cytoplasmic male sterility-encoding gene is reported, and the Petunia restorer of fertility gene product is a mitochondrially targeted protein that is almost entirely composed of 14 repeats of the 35-aa pentatricopeptide repeat motif.
Thoughts on Cytoplasmic Male Sterility in cms-T Maize.
TLDR
The basis of CMS in cms-T maize is considered, which is a maternally inherited trait that suppresses the production of viable pollen grains and is specifically susceptible to Bipolaris maydis race T.
The male sterile G cytoplasm of wild beet displays modified mitochondrial respiratory complexes.
TLDR
Two mutations of G mitochondrial genes are identified that results in the production of a respiratory chain complex subunit with an altered molecular weight in male sterile G plants, suggesting that this alternative pathway might compensate for the cytochrome c oxidase deficiency.
Mitochondrial transcript processing and restoration of male fertility in T-cytoplasm maize.
TLDR
AFLP bulk-segregant analysis has been used to identify DNA markers closely linked to the Rf8 locus that will provide a foundation for determining mechanisms of nuclear-directed mitochondrial RNA processing and fertility restoration.
Unique aspects of cytoplasmic male sterility and fertility restoration in Brassica napus
TLDR
Findings made are consistent with the view that new alleles of a restorer locus arise in response to natural selective pressures generated by the appearance of new male sterile cytoplasms.
