Polyploidy is widespread in plants and less frequent in animals but serves as an important speciation mechanism in both groups. Polyploidy is accompanied by drastic changes in genome organization including differential patterns of gene loss, gene silencing, genome-wide expression dominance, and epigenetic reprogramming. One underexplored dimension of polyploid evolution is cytonuclear interactions. Allopolyploid animals must ensure coordination between the effectively haploid and typically uniparentally inherited mitochondrial genome and the duplicated biparentally inherited nuclear genome. In allopolyploid plants, an additional cytoplasmic genome (the plastome) must interact with the duplicated nuclear genome. Whole genome duplication may lead to a stochiometric imbalance between these interacting genomes and perturb the assembly of enzyme complexes and the proper functioning of mitochondria and chloroplasts. Recent studies have shown compensatory mechanisms in young plant polyploids with organelle-targeting nuclear genes returning to a single copy following polyploidization. In animals, the mitochondrial genome is typically inherited maternally and numerous cases of hybrid breakdown and incompatibilities have been traced to the disruption of cytonuclear coordination in diploids. However, not much is known about how doubling the nuclear genome perturbs interactions with the mitochondrial genome in polyploid animals or plants. As polyploidy allows new interactions between highly divergent cytoplasmic and nuclear genomes, cytonuclear interactions may be more challenging in allopolyploids than in diploid hybrids.
This Special Issue aims to explore and contrast coordination and coevolution between cytoplasmic and nuclear genomes in both plant and animal polyploids.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Genes is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
