The study of plant–microbe interactions and the characterization plant-associated microbiota has been focus plant researchers in last decades due to its importance for health natural conditions. Here, I explore persistent core associated with different species across environments by performing a meta-analysis publicly available datasets. Intra-specific analyses revealed that diverse genotypes growing similar habitats interact common set microbial groups but some these are species- or environment-specific. Furthermore, interspecific demonstrates conservation seven bacterial orders photosynthetic organisms, including microalgae, suggesting conserved capacity interaction microbes throughout evolutionary history. However, specific functions members whether hosts remain largely unexplored. therefore discuss understanding roles propose future research directions, exploration kingdoms. By investigating functions, it will be possible leverage this knowledge sustainable agricultural management goals.

Abstract The social movement to reduce reliance on pesticides and synthesized fertilizers the growing global demand for sustainable food supplies require development of eco‐friendly agricultural practices. In line, plant growth‐promoting bacteria (PGPB) can participate in creating innovative agroecological systems. While effectiveness PGPB is highly influenced by abiotic conditions microbe–microbe interactions, beneficial plant–PGPB interactions also depend both host genotype. Here, state art extent natural genetic variation underlying architecture, particular Arabidopsis thaliana reviewed. Extensive response associated with a polygenic architecture pathways rarely mentioned as being involved PGPB. To date, within little explored, which may turn allow identification new benefits plants. Accordingly, several avenues better understand genomic molecular landscape are introduced.

Despite our emergent understanding of the contribution beneficial microbes to health humans and crops we eat, microbiome engineering improve plant has had limited success. Recent work shown that genotype plays a critical role in shaping so genetics must be considered practices. Here, review recent from lab others on plant-driven genetic molecular mechanisms shape plant-associated microbial communities. Based recruitment microbes, discuss challenges Canadian agriculture are strong candidates for engineering. These include pathogens have been difficult control through traditional methods including root rot pathogens, as well controlled agricultural systems like greenhouses vertical farming.

Plant microbiome interactions are bidirectional with processes leading to assembly and effects on plants, so called feedbacks. With belowground focus we systematically decomposed both of these directions into plant (root rhizosphere) components identify methodological challenges research priorities. We found that the bidirectionality presents a challenge for genetic studies. Establishing causality is particularly difficult when mutant has both, an altered phenotype microbiome.

The scale of genetic variation important to microbes is largely unknown, yet fundamental the community assembly host-associated microbiomes, with implications for eco-evolutionary dynamics hosts. Using Ipomoea hederacea , Ivy-leaved morning glory, we generated matrilines differing in quantitative leaf shape, which controlled a single Mendelian locus. We then investigated relative roles structuring microbiome, how these two sources contributed microbe heritability. found that despite large effects environment, contribute heritability, cumulative small effect genomic differences due matriline explained as much or more microbial than Furthermore, our results first suggest shape itself contributes abundances some phyllosphere microbes.

Abstract Switchgrass ( Panicum virgatum L.) is considered a sustainable biofuel feedstock, given its fast-growth, low input requirements, and high biomass yields. Improvements in bioenergy conversion efficiency of switchgrass could be made by reducing lignin content. Engineered that expresses bacterial 3-dehydroshikimate dehydratase (QsuB) has reduced content improved saccharification due to the rerouting shikimate pathway towards simple aromatic protocatechuate at expense biosynthesis. However, impacts this QsuB trait on microbiome structure function remains unclear. To address this, wildtype engineered were grown field soils samples collected from inflorescences, leaves, roots, rhizospheres, bulk for analysis. We investigated how expression influenced switchgrass-associated fungal communities using high-throughput Illumina MiSeq amplicon sequencing ITS 16S rDNA. Compared wildtype, hosted different microbial rhizosphere, leaves. Specifically, plants had lower abundance arbuscular mycorrhizal fungi (AMF). Additionally, fewer Actinobacteriota root rhizosphere samples. These findings may indicate changes plant metabolism impact both organismal groups similarly, or potential interactions between AMF community. This study enhances understanding plant-microbiome providing baseline data developing beneficial bioengineering strategies assessing non-target traits microbiome.
