Special Issue Information
Dear Colleagues,
Biological nitrogen fixation (BNF) is the predominant source of biologically available nitrogen species to ecosystems. This process of the nitrogen cycle is of great agronomic and environmental importance for sustainability and food security, as it reduces the need for chemical fertilizers to maintain the productivity of staple crops. Rhizobia, the main contributors to BNF, consist of a large group of α- and β-proteobacteria that can form symbiotic associations with leguminous plants, inducing the formation of plant nodules where nitrogen fixation takes place. During this symbiotic interaction, rhizobia must respond to a battery of signals and consequently undergo severe changes in their physiology, from free-living conditions in the soil to a symbiotic state within the highly specialized environment of a plant cell. Biotic and abiotic stresses also affect the fitness of symbiotic efficiency. Recent insights from multidisciplinary disciplines including microbiology, genetics, molecular biology, biochemistry, biodiversity, and omics sciences have improved our understanding of the molecular mechanisms underlying rhizobia–plant interactions, which serves as a basis for the development of biotechnological tools and sustainable agricultural practices. This Special Issue aims to bring together the latest developments and state-of-the-art molecular research in the field of rhizobia, with original articles and concise reviews by experts in the field.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
