“…Similarly, M. truncatula mutants impaired in nodulation and/or AMF symbioses assemble more similar root bacterial communities compared to wild-type ( Offre et al, 2007 ). AMF and nodulation symbiosis play important roles in structuring the root fungal and bacterial communities, and disruption of symbiosis causes major shifts in bacterial and fungal assembly ( Thiergart et al, 2019 ; Wang et al, 2020 ). Numerous SWEETs across different plant families were shown to be induced during AMF and rhizobial symbiosis ( Fiorilli et al, 2015 ; Manck-Götzenberger and Requena, 2016 ), indicating an evolutionarily conserved role for some SWEETs in symbiosis.…”

“…Pseudomonas infection, and in particular, bacterial elicitors and jasmonic acid signaling induce AtALMT1 in the absence of a low pH or an aluminum-rich environment, leading to root secretion of malate, thereby promoting colonization by beneficial rhizobacteria and conferring systemic immunity against subsequent pathogen infection ( Table 4 ; Figure 5 ; Rudrappa et al, 2008 ; Lakshmanan et al, 2012 ; Berendsen et al, 2018 ). In wheat, lines carrying either wild-type or mutant TaALMT1 alleles showed differences in host-associated bacterial taxa, reminiscent of that caused by symbiosis disruptions ( Thiergart et al, 2019 ; Wang et al, 2020 ). Whether such differences are attributed to malate secretion have not yet been tested ( Mahoney et al, 2017 ).…”

Cellular export of sugars and amino acids: role in feeding other cells and organisms

Sucrose, hexoses and raffinose play key roles in plant metabolism. Sucrose and raffinose, produced by photosynthesis, are translocated from leaves to flowers, developing seeds and roots. Translocation occurs in the sieve elements or sieve tubes of angiosperms. But how is sucrose loaded into and unloaded from the sieve elements? There seem to be two principal routes: one through plasmodesmata and one via the apoplasm. The best-studied transporters are the H+/SUCROSE TRANSPORTERs (SUTs) in the sieve element-companion cell complex. Sucrose is delivered to SUTs by SWEET sugar uniporters that release these key metabolites into the apoplasmic space. The H+/amino acid permeases (AAPs) and the UmamiT amino acid transporters are hypothesized to play analogous roles as the SUT-SWEET pair to transport amino acids. SWEETs and UmamiTs also act in many other important processes – for example, seed filling, nectar secretion, and pollen nutrition. We present information on cell type specific enrichment of SWEET and UmamiT family members and propose several members to play redundant roles in the efflux of sucrose and amino acids across different cell types in the leaf. Pathogens hijack SWEETs and thus represent a major susceptibility of the plant. Here, we provide an update on the status of research on intercellular and long-distance translocation of key metabolites such as sucrose and amino acids, communication of the plants with the root microbiota via root exudates, discuss the existence of transporters for other important metabolites and provide potential perspectives that may direct future research activities.

“…One explanation might be that the common symbiosis pathway in legumes is shared beyond rhizobia and arbuscular mycorrhizal fungi (AMF) (Skiada et al, 2020). For example, Medicago truncatula mutants unable to establish AMF symbiosis grown in field soil under greenhouse conditions had reduced microbial abundance in the rhizosphere, suggesting a role for conserved symbiotic pathways in rhizosphere enrichment processes (Wang et al, 2021). Although flavonoids are present across the plant kingdom (e.g., Lapcik et al, 2006;Tian et al, 2021), accumulated evidence suggests they are particularly prevalent among legumes (Veitch, 2007;Jasiński et al, 2009) and their importance in multiple initiation and regulatory functions pertaining to intracellular symbiosis cannot be understated.…”

Legumes are of primary importance for agroecosystems because they provide protein-rich foods and enhance soil fertility through fixed atmospheric nitrogen. The legume-rhizobia symbiosis that makes this possible has been extensively studied, from basic research on biochemical signaling to practical applications in cropping systems. While rhizobia are the most-studied group of associated microorganisms, the functional benefit they confer to their legume hosts by fixing nitrogen is not performed in isolation. Indeed, non-rhizobia members of the rhizosphere and nodule microbiome are now understood to contribute in multiple ways to nodule formation, legume fitness, and other agroecosystem services. In this review, we summarize advances contributing to our understanding of the diversity and composition of bacterial members of the belowground legume microbiome. We also highlight applied work in legume food and forage crops that link microbial community composition with plant functional benefits. Ultimately, further research will assist in the development of multi-species microbial inoculants and cropping systems that maximize plant nutrient benefits, while reducing sources of agricultural pollution.

“…Interestingly, Wang et al . (2021b) found that in Medicago truncatula grown in natural soils, AM symbiosis not only shapes the bacterial rhizosphere microbiome composition in general but specifically promotes the enrichment of rhizobia in the rhizosphere, and thereby the formation of nodules. Notably, root nodules themselves are not only colonized by one rhizobial strain but host a whole bacterial community.…”

SUMMARY Soil is a living ecosystem, the health of which depends on fine interactions among its abiotic and biotic components. These form a delicate equilibrium maintained through a multilayer network that absorbs certain perturbations and guarantees soil functioning. Deciphering the principles governing the interactions within soils is of critical importance for their management and conservation. Here, we focus on soil microbiota and discuss the complexity of interactions that impact the composition and function of soil microbiota and their interaction with plants. We discuss how physical aspects of soils influence microbiota composition and how microbiota–plant interactions support plant growth and responses to nutrient deficiencies. We predict that understanding the principles determining the configuration and functioning of soil microbiota will contribute to the design of microbiota‐based strategies to preserve natural resources and develop more environmentally friendly agricultural practices.
