Special Issue Information
Dear Colleagues,
In recent years, the role of the plant microbiome has emerged as a central topic within the field of plant physiology. Ubiquitous in nature, microorganisms can colonize a variety of ecological niches within (endosphere, phyllosphere) or close (rhizosphere) to plants, establishing complex chemical dialogues with the host tissues that can drive different types of relationships. However, how these interactions influence plant growth and development is still poorly understood. One of the main strategies used by microorganisms to influence crop behavior is based on their ability to synthesize plant growth regulators (PGRs) or closely related compounds, that once released in the tissues modulate the behavior of the host plant. These actions modify gene expression, secondary metabolite production and overall crop performance, thus directly impacting crop yield. On the other hand, plants’ own PGRs also have a relevant effect on the assembly and performance of the microbiome, establishing a chemical arms race that ultimately impacts plant fitness. All in all, the modulation of hormone homeostasis influences plant growth, development, fruit production or defense responses, among other processes. Therefore, a deeper understanding of these relations might enable the development of new strategies for a more sustainable agriculture.
The aim of this Special Issue is to provide authors with a platform to share their work analyzing the interactions of members of the microbiome (mainly bacteria and fungi) with the growth and development of crops and its interplay with PGRs. Manuscripts dealing with the characterization of microbiome populations, their effect on plant gene expression, the influence of PGRs on their interplay, or any other analysis that can help improve the understanding of their interactions are welcomed. Moreover, controlled studies dealing with the effect of inoculating particular sets of microbes or specific hormone treatments may be necessary to further clarify these relationships. Gene editing studies or systems biology approaches might also be of interest.

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. Agriculture 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 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.
