Additionally, new findings indicate that final outcomes for host fitness can be dependent not only on the exchange of goods between the host and microbe, but on signaling and metabolic interactions among members of the microbiome themselves [14,15,16].

These soil microbiomes can shift drastically in abundance, composition, and activity over short physical distances, timeframes, and in response to seasonal environmental factors, which increases the source diversity from which plants draw their microbiomes [ 19, 20, 21 ]. Microbiomes play a pivotal role in plant growth and health, but the genetic factors involved in microbiome assembly are still in their infancy (Escudero-Martinez et al., 2022; Oyserman et al., 2022).

We also discuss how those interactions shape the assembly of plant-associated microbiomes and modulate their beneficial traits, such as nutrient acquisition and plant health, in addition to highlighting knowledge gaps and future directions. 2020;11:944. In order to quantify networks of microbe interactions on A. thaliana leaves, we calculated the relative OTU abundance of primary, secondary leaders, tertiary leaders and followers in the mutualism network, the relative OTU abundance of two antagonists in the antagonism network, the relative OTU abundance of hawks and doves in the aggression network, and the relative OTU abundance of altruist and egoists in the altruism network (Wu et al., 2021). Nectar bacteria stimulate pollen germination and bursting to enhance microbial fitness, Plant evolution driven by interactions with symbiotic and pathogenic microbes. In addition, we discuss the biggest challenges for conducting holo-omics studies; specifically, the lack of vetted analytical frameworks, publicly available tools, and required technical expertise to process and integrate heterogeneous data. To reduce the bias, we statistically identify the hub taxa with the higher degree and closeness centrality (Gao et al., 2021; He et al., 2021). We also investigate candidate genes within ~10kb windows on each side of associated SNPs by software PLINK. This review highlights the pivotal role of root exudates in the rhizosphere, especially the interactions between plants and microbes and between plants and plants.

Of the many ways that plants interact with microbes, three aspects are highlighted in this issue: interactions where the plant benefits from the microbes, interactions where the plant suffers, and interactions where the plant serves as habitat for microbial communities.

We envision that systems-level understanding of plant-microbiome interactions spanning from molecular levels to ecosystem levels across time and space will provide both the parts and wiring diagrams to refine the models to generate more realistic predictions. Li X, Jousset A, de Boer W, Carrin VJ, Zhang T, Wang X, et al. These microorganisms interact dynamically with plants and influence their hosts growth and development. To improve understanding of how plant-microbiome-environment interactions may alter the timing of spring phenology, we combined field observations and a reciprocal population-level greenhouse. This design allowed for the investigation of differences influenced by sample compartments (leaf, root, rhizosphere, and soil), by genotype (RTx430 and BTx642), by watering treatment (irrigation and drought), and by plant development (from seedling emergence to grain maturation) [44]. Taken together, the above examples indicate how collecting a combination of microbial and host data is a promising approach to further unraveling plant and bacterial community interactions through generating mechanism-based questions and testable hypotheses.

Microbial community structure and dynamics in thermophilic composting viewed through metagenomics and metatranscriptomics. By integrating behavioral ecology and game theory, Wu and team developed mathematical descriptors for quantifying and characterizing different types of microbial interactions, including mutualism (two microbes promotes each other), antagonism (two microbes inhibit each other), aggression (a stronger microbe is aggressive to a weaker microbe), and altruism (one microbe benefit the other), in ecological communities at any large scale (Jiang et al., 2019; Wang et al., 2019).
