“…This SynComs approach was used by Lebeis, et al [ 53 ], who revealed that the defense phytohormone salicylic acid modulates bacterial colonization of the roots of Arabidopsis. These available tools allow us to unknot the entangled networks of interactions of fundamental microbiomes or holobionts for efficiently using the root microbiome to intensify crops’ nutrient procurement and fight against biotic and abiotic stress [ 54 ].…”

Plant roots host numerous microorganisms around and inside their roots, forming a community known as the root microbiome. An increasing bulk of research is underlining the influences root-associated microbial communities can have on plant health and development. However, knowledge on how plant roots and their associated microbes interact to bring about crop growth and yield is limited. Here, we presented (i) the communication strategies between plant roots and root-associated microbes and (ii) the applications of plant root-associated microbes in enhancing plant growth and yield. This review has been divided into three main sections: communications between root microbiome and plant root; the mechanism employed by root-associated microbes; and the chemical communication mechanisms between plants and microbes and their application in plant growth and yield. Understanding how plant root and root-associated microbes communicate is vital in designing ecofriendly strategies for targeted disease suppression and improved plant growth that will help in sustainable agriculture. Ensuring that plants become healthy and productive entails keeping plants under surveillance around the roots to recognize disease-causing microbes and similarly exploit the services of beneficial microorganisms in nutrient acquisition, stress mitigation, and growth promotion.

“…Several authors have described the importance and ecological interpretations of the cross-kingdom co-occurrence networks in the plant microbiome [ 162 , 163 ]. Network analyses have identified the existence of interactions among the myriad of endophytes present in natural communities and other potential higher-order interactions [ 164 ]. Thus, this analysis has contributed to the discovery of hub or keystone microbial taxa in the plant microbiome.…”

“…The plant-associated metagenomes are defined as the set of genes encoded by any particular microbiota that can provide the host plant with critical nutrients, protection from plant pathogens, production of functional plant hormones and tolerance to abiotic stresses, etc. Metagenomics will also contribute to improving our understanding of species composition, genetic diversity, inter-species interactions and species evolution in the context of different ecological niches [ 164 ]. However, to the best of our knowledge, to date, only one study has analyzed the olive xylem microbiome by metagenomic analysis, and was conducted by Giampetruzzi et al (2020) [ 102 ].…”

Vascular pathogens are the causal agents of some of the most devastating plant diseases in the world, which can cause, under specific conditions, the destruction of entire crops. These plant pathogens activate a range of physiological and immune reactions in the host plant following infection, which may trigger the proliferation of a specific microbiome to combat them by, among others, inhibiting their growth and/or competing for space. Nowadays, it has been demonstrated that the plant microbiome can be modified by transplanting specific members of the microbiome, with exciting results for the control of plant diseases. However, its practical application in agriculture for the control of vascular plant pathogens is hampered by the limited knowledge of the plant endosphere, and, in particular, of the xylem niche. In this review, we present a comprehensive overview of how research on the plant microbiome has evolved during the last decades to unravel the factors and complex interactions that affect the associated microbial communities and their surrounding environment, focusing on the microbial communities inhabiting the xylem vessels of olive trees (Olea europaea subsp. europaea), the most ancient and important woody crop in the Mediterranean Basin. For that purpose, we have highlighted the role of xylem composition and its associated microorganisms in plants by describing the methodological approaches explored to study xylem microbiota, starting from the methods used to extract xylem microbial communities to their assessment by culture-dependent and next-generation sequencing approaches. Additionally, we have categorized some of the key biotic and abiotic factors, such as the host plant niche and genotype, the environment and the infection with vascular pathogens, that can be potential determinants to critically affect olive physiology and health status in a holobiont context (host and its associated organisms). Finally, we have outlined future directions and challenges for xylem microbiome studies based on the recent advances in molecular biology, focusing on metagenomics and culturomics, and bioinformatics network analysis. A better understanding of the xylem olive microbiome will contribute to facilitate the exploration and selection of specific keystone microorganisms that can live in close association with olives under a range of environmental/agronomic conditions. These microorganisms could be ideal targets for the design of microbial consortia that can be applied by endotherapy treatments to prevent or control diseases caused by vascular pathogens or modify the physiology and growth of olive trees.

“…The endo-rhizosphere is inhabited by root endophytes (microbes living inside the roots) while the exophytes (microbes living outside of the roots) inhabit the ecto-rhizosphere [3]. Epiphytic (surface-dwelling) microbes colonize the rhizoplane (Figure 1) [4]. Rhizosphere is home to many organisms including bacteria, fungi, actinomycetes, protozoa, algae, nematodes, and arthropods [1,5].…”

The rhizosphere is a dynamic ecosystem consisting of a plethora of microorganisms. The rhizosphere microbiome plays diverse roles in cereal plants. Among them, the bacterial population associated with roots including exophyte microbes and endophytes has a direct impact on plant development and health. In this chapter, we describe the rhizosphere bacterial microbiome in cereals, meta-genomics studies, isolation and identification of rhizobacterial endophytes and exophytes in different cereal plants, characterization of cereal rhizobacteria, and the potential roles of the rhizobacteria in cereal crops. The potential roles of these microbes will be pathogenic, parasitic, neutral, growth-promoting, stress-tolerant, biocontrol, etc. Overall, this chapter will explore the recent research advances and updates in rhizobacteria in cereal crops.
