Globally, agriculture relies on supplementing cropped soils with macro and micronutrients sourced from mined ores or industrially produced through energy intensive processes. The major outcome of supplementing crops with these fertilizers is a consistent yield, however, as global demand for fertilizers increases, the costs associated with the production for each of these major nutrients increase. There are also numerous, well-characterized, negative impacts of chemical fertilizer use, including pollution, eutrophication and soil depletion.
Plant growth promoting bacteria (PGPB), which naturally occur in soils and aggressively colonize around plant roots, have been shown to promote plant growth by various direct and indirect mechanisms. The potential of PGPB to reduce dependence on high levels of fertilizer inputs has gained significant increase in interest over recent years.
Sustainably improving agricultural production by plant growth-promoting microorganisms is a promising field of research; however, there still exist significant gaps in the understanding of the actual mechanism of plant growth promotion. This Special Issue of Agronomy is dedicated to PGPB with a particular focus on their mode of action, examples of innovative methodologies for their characterization of the mode of action and analysis of their interaction with the host plant.

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 papers will be 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. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.

Abstract：Background From bacterial quorum sensing to bees’ signals, communication is the basis of biotic interactions. Frequently, more than two organisms can take part in the speeches, resulting in a complex network of cross-talks. Recent advances in plant-microbe interactions research have shown that communication, both inter-kingdom and intra-kingdom, is shaped by a broad spectrum of factors. In this context, the rhizosphere (i.e., the soil close to the root surface) provides a specific microhabitat where complex interactions occur. Scop: The aim of this review is to explore the components of such rhizospheric Talk Show in the frame of the rhizobium-legume interactions. This symbiosis is a complex process that involves several signals that can be shaped by plant rhizospheric exudates and microbiome composition. Here, we synthesize research that accounts for strategies, molecules, and organisms that influence the place of rhizobia in the rhizosphere, accounting for the most recent approaches for the study and the subsequent exploitation of organism’s diversity. Conclusion The complex environment that makes up the rhizosphere can select for certain microbial populations, which are adapted to this unique niche. Among them, rhizobia are coming out as an important component of the rhizospheric microbiome. We argue the relationship that rhizobia can entertain with other rhizospheric organisms including the impact of abiotic environmental and host factors, pointing out the beneficial role that these bacteria can play on plant health. The study of plant-microbes communication and of its evolution is fundamental for exploitation of such interactions to develop highly efficient inoculants to reduce the use of fertilizers in agriculture.
