Special Issue Information
Dear Colleagues,
The evolution of nitrogen-fixing root nodule symbioses comprises the evolution of the host, the microsymbiont, as well as their co-evolution.
In the last two years, the increased application of phylogenomics approaches enabled by the growing number of sequenced genomes of host plants has led to breakthroughs. Large-scale analyses of epigenetic changes and of non-coding RNAs have been added to the arsenal of researchers. Nevertheless, there are still a lot of open questions which should be answered based on the available tools: What is the basis for symbiotic efficiency—the adaptation of a particular microsymbiont to a particular host is an ongoing evolutionary process, but what are the molecular players? What is the molecular basis for the induction of legume nodules without infection threads formed in root hairs? Which host features are responsible for the accommodation of rhizobia in symbiosomes instead of fixation threads? What are the signal factors of Frankia strains? What are the reasons for the loss of the symbiosis in the majority of plant lineages derived from the common ancestor of Fabales, Fagales, Cucuribtales, and Rosales? The forthcoming Special Issue aims to present a platform for the discussion of these new developments in root nodule symbioses.

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 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. 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 2600 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.
