* *Abstract**

The intricate relationships between plants and their associated microbiome play a crucial role in shaping the plant's defense against pathogens and its ability to acquire essential nutrients. In this study, we employed a multi-omics approach to elucidate the plant-microbiome axis in disease resistance and nutrient uptake in agriculturally relevant crop species. We herein present key findings from our network analysis, highlighting the complex interplay between plant metabolic pathways, microbial communities, and environmental factors. Our results provide novel insights into the mechanisms underlying systemic acquired resistance and enhanced nutrient acquisition, paving the way for the development of precision agriculture strategies and more effective disease management practices.

* *Introduction**

Plants have evolved complex defense mechanisms to counteract pathogen attack and maintain their nutritional balance. The plant-microbiome axis, comprising the plant's metabolic network and its associated microbial community, plays a pivotal role in this process. A better understanding of the interactions between plants and their microbiome is essential for developing effective disease management strategies and improving crop yields.

* *Key Findings**

Our network analysis revealed several key drivers of systemic acquired resistance and enhanced nutrient acquisition in agriculturally relevant crop species. Firstly, we identified a set of plant metabolic pathways, including the phenylpropanoid and terpenoid pathways, that are involved in the synthesis of defense-related metabolites. These pathways are modulated by the plant's associated microbiome, which in turn influences the plant's resistance to pathogens.

Secondly, we found that the plant-microbiome axis is shaped by environmental factors, including soil pH, temperature, and moisture. These factors influence the composition and activity of the microbial community, which in turn affects the plant's metabolic network and its ability to acquire nutrients.

Thirdly, we discovered that certain microbial species, such as those belonging to the genus _Trichoderma_, play a key role in promoting plant growth and defense against pathogens. These microbes produce secondary metabolites that stimulate plant growth and induce systemic acquired resistance.

* *Botanical Mechanisms**

The plant-microbiome axis is mediated by a complex network of signaling pathways, including the salicylic acid (SA) and jasmonic acid (JA) pathways. These pathways are involved in the regulation of plant defense responses and the synthesis of defense-related metabolites.

In addition, the plant-microbiome axis is influenced by the plant's hormonal balance, including the auxin, cytokinin, and ethylene pathways. These hormones play a crucial role in regulating plant growth and development, as well as the plant's response to environmental stresses.

* *Methods/Diagnostics**

Our study employed a multi-omics approach, including transcriptomics, metabolomics, and microbiomics, to elucidate the plant-microbiome axis in disease resistance and nutrient uptake. We used high-throughput sequencing and mass spectrometry to analyze the plant's transcriptome, metabolome, and microbiome.

We also used symptom scoring and environmental measurements to assess the plant's growth and development, as well as its response to pathogens and environmental stresses.

* *Interpretation**

Our results provide novel insights into the mechanisms underlying systemic acquired resistance and enhanced nutrient acquisition in agriculturally relevant crop species. We found that the plant-microbiome axis is shaped by a complex interplay between plant metabolic pathways, microbial communities, and environmental factors.

Our study highlights the importance of considering the plant-microbiome axis in disease management strategies and crop improvement programs. By understanding the complex interactions between plants and their microbiome, we can develop more effective disease management practices and improve crop yields.

* *Diagnostic Thresholds/Assay Caveats**

Our study employed a multi-omics approach to elucidate the plant-microbiome axis in disease resistance and nutrient uptake. However, the interpretation of our results is subject to several caveats.
