Reading the evidence in public health and nutrition
Population and nutrition studies mostly observe what people eat, breathe or are exposed to and then look for links with health, which shows association and not proof of cause. Self-reported diet is imprecise, people who eat or live differently also differ in other ways, and effects measured across a population may not apply to one person. Check the study design, how exposure was measured, what else was accounted for and the size of the effect, not only whether it was statistically significant.
Evidence from open-access studies
These open-access studies come from PubMed’s best-match results for this heading (papers whose main topic it is), ranked here by citation count, with one recent addition. Each abstract is reproduced in full under its recorded open licence so that you can read the authors’ own words. They illustrate the literature; they are not a systematic summary of it. Citation counts measure attention, not reliability or clinical benefit.

Microbial communities play a crucial role in supporting plant health and productivity. Reproducible, natural plant-associated microbiomes can help disentangle microbial dynamics across time and space. Here, using a sequential propagation strategy, we generated a complex and reproducible wheat rhizosphere microbiome (RhizCom) to study successional dynamics and interactions between the soil and heritable seed-borne rhizosphere microbiomes (SbRB) in a microcosm. Using 16S rRNA sequencing and genome-resolved shotgun metagenomics, we find that SbRB surpassed native soil microbes as the dominant rhizosphere-associated microbiome source. SbRB genomes were enriched in host-associated traits including degradation of key saccharide (niche partitioning) and cross-feeding interactions that supported partner strains (niche facilitation). In vitro co-culture experiments confirmed that helper SbRB strains facilitated the growth of partner bacteria on disaccharides as sole carbon source. These results reveal the importance of seed microbiota dynamics in microbial succession and community assembly, which could inform strategies for crop microbiome manipulation.

Plant growth behavior is a function of genetic network architecture. The importance of root microbiome variation driving plant functional traits is increasingly recognized, but the genetic mechanisms governing this variation are less studied. Here, we collect roots and rhizosphere soils from nine Populus species belonging to four sections (Leuce, Aigeiros, Tacamahaca, and Turanga), generate metabolite and transcription data for roots and microbiota data for rhizospheres, and conduct comprehensive multi-omics analyses. We demonstrate that the roots of vigorous Leuce poplar enrich more Pseudomonas, compared with the poorly performing poplar. Moreover, we confirm that Pseudomonas is strongly associated with tricin and apigenin biosynthesis and identify that gene GLABRA3 (GL3) is critical for tricin secretion. The elevated tricin secretion via constitutive transcription of PopGL3 and Chalcone synthase (PopCHS4) can drive Pseudomonas colonization in the rhizosphere and further enhance poplar growth, nitrogen acquisition, and secondary root development in nitrogen-poor soil. This study reveals that plant-metabolite-microbe regulation patterns contribute to the poplar fitness and thoroughly decodes the key regulatory mechanisms of tricin, and provides insights into the interactions of the plant's key metabolites with its transcriptome and rhizosphere microbes.

The plant microbiome comprises a wide range of microorganisms associated with different plant tissues. Over the past decades, significant research efforts have focused on understanding and harnessing the plant rhizosphere microbiome for optimal plant growth and health. However, while environmental factors are often the primary focus of these studies, the influence of plant genotype remains comparatively underexplored. In fact, the plant genotype influences a multitude of factors including root morphology and exudate composition, which play an integral role in shaping the rhizosphere niche. In this review, we discuss how alterations in plant host genetics could lead to differences in the assembly and diversity of the rhizosphere microbiome. Furthermore, we summarize current approaches to decipher complex plant traits and their ecological implications in host-microbiome systems and interactions.

Halophytic plants harbour salt-tolerant bacteria that enhance resilience to salinity. In this study, two highly halotolerant Kushneria isolates, K. konosiri (Kk) and K. marisflavi (Km), were obtained from the halophyte Suaeda maritima. Both strains tolerated up to 25% NaCl and promoted Arabidopsis thaliana growth under salt stress by producing indole-3-acetic acid, proline, and extracellular polysaccharides that mitigated osmotic stress. Inoculation with Kk or Km increased shoot and root biomass and reduced intracellular Na⁺ and reactive oxygen species. Their agricultural potential was tested in cabbage (Brassica rapa), where both isolates alleviated salinity-induced growth inhibition. A combined inoculum (Kkm) showed enhanced efficacy, significantly increasing shoot biomass (1.26-fold vs. Kk; 1.23-fold vs. Km) and dry weight (1.19-fold vs. Kk; 1.13-fold vs. Km). Kkm treatment also improved the K⁺/Na⁺ ratio and proline accumulation. Microbial profiling revealed that Kkm enriched Bacillus species in the rhizosphere and promoted greater biofilm formation than single strains. These findings demonstrate that Kushneria isolates function as salt-tolerant plant growth-promoting bacteria, enhancing ion homoeostasis, stress protection, and rhizosphere restructuring. This study highlights the potential of halophyte-derived microbial consortia to improve crop salt tolerance in agriculture.
