Review. The soil-borne identity and microbiome-assisted agriculture: Looking back to the future (Molecular Plant)

Bakker et al. begin their review of plant-soil microbiome concepts with a Lorentz Hiltner quote from 1904: “However, I am convinced that soil bacteriology will finally provide results that are not only of explanatory nature, but will also directly affect and determine agricultural practice… I would…

Review: Coumarin communication along the microbiome-root-shoot axis (Trends Plant Sci.)

As the realm of microbiology expands, we see increasing ways in which eukaryotes depend on their microbiomes. For instance, in animals, the “microbiome-gut-brain axis” connects gut microbiota and the nervous system and influences a range of activities from digestion to mental health. Stassen et al.…

Review: La vie en roses, lilies, and other flowers: the floral microbiome (Annu. Rev. Ecol. Evol. Syst.)

Beyond their beautiful colors, fragrances and shapes, flowers also can host a great variety of life forms. A diverse community of bacteria, fungi, protozoa, and other organisms live in the flowers. A recent work by Rachel Vannette summarizes the current studies about the floral microbiome, highlighting…

Coordination of microbe-host homeostasis via a crosstalk with plant innate immunity (Research Square)

In nature, roots are colonized by commensal bacteria that do not seem to influence host traits. Recently, studies showed some commensals can suppress plant immune responses when inoculated to plants alone. However, how such commensal activities are coordinated in the community context is poorly understood.…

Review: Plant–microbiome interactions: from community assembly to plant health (Nat. Rev. Microbiol)

The association of plants with communities of beneficial microbes,  called plant microbiota, has a positive effect on growth and proliferation of both organisms. Recent findings in plant microbiota research uncovered the role of individual microbes and associated genes during plant-microbe interaction…

Review. The plant microbiome: From ecology to reductionism and beyond (Annu. Rev. Microbiol.)

The last two decades have witnessed tremendous progress in our understanding of plant microbiota. Fitzpatrick, Salas-González et al. highlight recent discoveries from culture-dependent and culture-independent approaches and discuss the future path towards integrating these approaches. Culture-independent…

Review: An extended root phenotype: the rhizosphere, its formation and impacts on plant fitness (Plant J.)

The rhizosphere is a continuous space for microbial colonization that comprises the rhizospheric soil, the rhizoplane (root surface), and the root endosphere, which is the apoplastic space in the root cortex. It is inhabited by unique populations of microorganisms, influenced by plant genotype and the…

Measuring both microbial load and diversity with a single amplicon sequencing library (bioRxiv)

Amplicon sequencing of microbial DNA is a gold standard for analyzing the relative abundance of microbes in host-associated microbiomes. To gain more accurate insights into microbiome changes, it is crucial to know the absolute abundance of microbes, which can be analyzed by integrating relative abundance…

Rhizosphere microbiome protects plants from a pathogen via iron competition (Nature Microbiol)

Iron is an essential element for most living organisms, including plant-associated bacteria. As iron is insoluble in most soils, many soil-borne bacteria scavenge iron using siderophores, a chemically diverse group of secondary metabolites with a high affinity for iron. Siderophores are known to drive…
