    Maternal spindle transfer overcomes embryo developmental arrest caused by ooplasmic defects in mice

    Nuno Costa-Borges et al.
    Maternal spindle transfer is a feasible approach to enhance embryonic developmental of compromised oocytes, which can represent a new strategy for patients with forms of infertility refractory to current treatments.

    Nutrient status shapes selfish mitochondrial genome dynamics across different levels of selection

    Bryan L Gitschlag et al.
    Food supply and nutrient stress tolerance coordinately shape the multilevel selection dynamics of a mitochondrial cheater by promoting cheater persistence at both within-host and between-host levels of selection.

    Stochastic modelling, Bayesian inference, and new in vivo measurements elucidate the debated mtDNA bottleneck mechanism

    Iain G Johnston et al.
    New modelling, statistics, and experiments show that cellular populations of mitochondrial DNA (mtDNA) evolve during development according to solvable stochastic dynamics involving binomial partitioning and random turnover, facilitating a predictive and quantitative theory of the mtDNA bottleneck.

    Introduction of a male-harming mitochondrial haplotype via ‘Trojan Females’ achieves population suppression in fruit flies

    Jonci Nikolai Wolff et al.
    Mitochondrial genomes harbor male-fertility-reducing mutations that can be harnessed to control population viability as a novel approach to control economic and environmental pests.

    Origins and functional consequences of somatic mitochondrial DNA mutations in human cancer

    Young Seok Ju et al.
    Identifying 1,907 mitochondrial somatic mutations from 1,675 tumor tissues provides new insights into the causes and effects of the mitochondrial genome mutations found in human cancers.

    A mitochondrial DNA hypomorph of cytochrome oxidase specifically impairs male fertility in Drosophila melanogaster

    Maulik R Patel et al.
    A 'male-harming' mtDNA mutation has been identified in Drosophila and impairs male fertility without impairing other male or female functions.

    Sugar promotes vegetative phase change in Arabidopsis thaliana by repressing the expression of MIR156A and MIR156C

    Li Yang et al.
    Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

    Mitochondrial genetic diversity, selection and recombination in a canine transmissible cancer

    Andrea Strakova et al.
    Genetics of a canine transmissible tumour show how the world’s oldest cancer “metastasised” through the global dog population – and captured, maintained and rearranged its mitochondrial DNA along the way.

    The need for high-quality oocyte mitochondria at extreme ploidy dictates mammalian germline development

    Marco Colnaghi et al.
    Selective transfer of mitochondria in the Balbiani body ensures high-quality oocyte mitochondria at extreme ploidy, explaining many enigmatic features of female germline architecture including germ cell loss.
