Special Issue Information

Dear Colleagues,

As is well known, plants harbor a community of microorganisms, forming a complex microbial ecosystem that significantly influences their growth, development, and stress tolerance. Despite remarkable progress in understanding this diverse microbial world, significant gaps remain in our knowledge regarding how these interactions are regulated, how they influence the assembly of the plant microbiome, and how they ultimately impact plant health. Therefore, a deeper understanding of signalomics is essential to uncover the various potentials of microbiome–plant interactions and harness these potentials for agricultural purposes.

Microbes communicate through signaling molecules that influence gene expression. Communication among microbes occurs through quorum sensing (QS), a cell-to-cell signaling process involving cell density-dependent coordination. QS includes the synthesis, release, and detection of chemical signals known as autoinducers, which regulate bacterial functions such as biofilm formation, adhesion, motility, propagation, virulence, metabolism, and symbiotic association. These processes play crucial roles in plant–microbe interactions. A holistic understanding of these communication pathways can aid in developing tailored microbial inoculants for enhanced plant growth and targeted disease suppression.

This Special Issue delves into recent research on plant–microbe interactions. It specifically focuses on unraveling the molecular signaling within the intricate microbial communities that are associated with plants. Studies that shed light on this communication are particularly welcome. They will help us to understand the molecular mechanisms underlying the recruitment and assembly of functionally diverse plant microbiota from the environment. Unveiling how these microbial communities are assembled is a key challenge in plant microbiome research. This knowledge will provide a crucial foundation for the precise manipulation of these communities for agricultural benefit.

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.
