“…Soil represents a major reservoir of microbial inoculum for plants (Zarraonaindia et al , 2015; Trivedi et al , 2020), especially belowground. However, we also observed that the effect driven by soil is a function of plant species, likely because the intrinsic characteristics of each plant species can modulate specific changes in the diversity and composition of microbial communities at each compartment (Turner et al , 2013; Dastogeer et al , 2020).…”

“…Plant species and genotype also contribute to the composition of multiple plant-associated microbiota (Turner et al , 2013). Plant microbial communities assemble differently in different organs, and their composition varies according to plant phylogeny (Dastogeer et al , 2020). Plant traits (tissue morphology and physicochemical properties) and resources might drive these plant-genotype effects on plant microbiota (Fitzpatrick et al , 2018; Dastogeer et al , 2020).…”

Plant traits (tissue morphology and physicochemical properties) and resources might drive these plant-genotype effects on plant microbiota (Fitzpatrick et al , 2018; Dastogeer et al , 2020). For example, an analysis of 30 species of angiosperms revealed differences in the diversity and composition of root microbiomes across plant species (Fitzpatrick et al , 2018).…”

Interactions between plants and microbiomes play a key role in ecosystem functioning, and are of broad interest due to their influence on nutrient cycling and plant protection. However, we do not yet have a complete understanding of how plant microbiomes are assembled. Here, for the first time, we show interactions between plant-associated microbial communities that drive their diversity and community composition. We manipulated soil microbial diversity, plant species, and herbivory, and found that soil microbial diversity influenced the herbivore-associated microbiome composition, but also plant species and herbivory influenced the soil microbiome composition. We used a novel approach, quantifying the relative strength of these effects, and demonstrated that the initial soil microbiome diversity explained the most variation in plant- and herbivore-associated microbial communities. Our findings strongly suggest that soil microbial community diversity is a driver of the composition of multiple associated microbiomes (plant and insect), and this has implications for the importance of management of soil microbiomes in multiple systems.

Through their roots, trees interact with a highly complex community of microorganisms belonging to various trophic guilds and contributing to tree nutrition, development and protection against stresses. Tree roots select for specific microbial species from the bulk soil communities. The root microbiome formation is a dynamic process but little is known on how the different microorganisms colonize the roots and how the selection occurs. To decipher if the final composition of the root microbiome is the product of several waves of colonization by different guilds of microorganisms, we planted sterile rooted cuttings of Gray Poplar obtained from plantlets propagated in axenic conditions in natural soil taken from a poplar stand. We analyzed the root microbiome at different time points between 2 and 50 days of culture by combining high-throughput Illumina MiSeq sequencing of fungal rDNA ITS and bacterial 16S rRNA amplicons with Confocal Laser Scanning Microscope observations. The microbial colonisation of poplar roots took place in three stages but the dynamic was different between bacteria and fungi. Root bacterial communities were clearly different from the soil after two days of culture. By contrast, if fungi were also already colonizing roots after two days, the initial communities were very close to the one of the soil and were dominated by saprotrophs. Those were slowly replaced by endophytes and ectomycorhizal fungi. The replacement of the most abundant fungal and bacterial community members observed in poplar roots along time suggest potential competition effect between microorganisms and/or a selection by the host.

“…The first article of this issue by Dastogeer et al [ 1 ] reviews the progress made in the growing field of the plant microbiome with a special focus on the drivers that shape the composition of the microbiome community. Engineering of plant microbiome to assist agriculture could have a profound effect on crop yield and resilience.…”
