Special Issue Information

Dear Colleagues,

Chromosome variation is one of the most investigated topics in higher plants.

For over a century, the number and morphology of chromosomes, the traits most detectable with simple cytological techniques, have been widely used to deduce important evolutionary events and to obtain information of phylogenetic relevance.

One of the first significant results of these studies is the discovery of polyploidy, that is, the massive increase in the number of chromosomes due to the multiplication of entire basic sets. Advances in chromosome analysis have enabled further progress, revealing that other mechanisms, such as ascending or descending dysploidy, have played a substantial role in the numerical and morphological changes of chromosomes and, ultimately, in karyotype evolution.

Cytogenetic data acquired during the past decades have irrefutably demonstrated the relationship between chromosome changes and the evolutionary history of plants. However, the effective consequences of karyotype diversity in plant evolution are still highly debated. There is evidence that karyotype changes act as driving forces in plant speciation by preventing hybridization through the rapid establishment of postzygotic crossing barriers. In contrast, chromosome changes are often regarded as a phenomenon that would only have reinforced or followed the speciation already begun by other factors. In the world of plants, there is still much to discover. New case studies will increase our understanding of karyotype diversity in plants by revealing different evolutionary paths in different plant taxa.

The purpose of this Special Issue of Plants, entitled “Chromosome Changes and Karyotype Evolution in Plants”, is to collect articles addressing the vast topic of chromosome diversity and its implications for plant evolution. Articles regarding new case studies are particularly welcome, as is the application of innovative techniques of analysis. We are encouraging the study of karyotype diversity, genome, and chromosome evolution in species or groups of species that have been ignored by cytogeneticists until now, and we invite researchers to offer us their results for this Special Issue. It is our conviction that the more we know about chromosome evolution, the better we can understand the complex mechanisms operating in plant evolution.

To realize this goal, we encourage the submission of original articles, reviews, and mini-reviews on the following:

  • Karyotype evolution and speciation;
  • Evolutionary pathways of karyotype diversity;
  • Dysploidy events and spaciation;
  • Insights into chromosome changes and genome evolution;
  • Karyotype evolution and phylogeny;
  • Genomic changes after polyploidization.

Manuscript Submission Information

Manuscripts should be submitted online at 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 submissions that pass pre-check are 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. Plants is an international peer-reviewed open access semimonthly 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 2700 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.
