Quality traits drive the enrichment of Massilia in the rhizosphere to improve soybean oil content

Microbiome, Journal Year: 2024, Volume and Issue: 12(1)

Published: Oct. 31, 2024

Soybean seeds are rich in protein and oil. The selection of varieties that produce high-quality has been one the priorities soybean breeding programs. However, influence improved seed quality on rhizosphere microbiota whether is involved determining still unclear. Here, we analyzed structures rhizospheric bacterial communities 100 varieties, including 53 landraces 47 modern cultivars, evaluated interactions between traits bacteria.

Root hair developmental regulators orchestrate drought triggered microbiome changes and the interaction with beneficial Rhizobiaceae

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Nov. 20, 2024

Drought is one of the most serious abiotic stresses, and emerging evidence suggest plant microbiome affects drought tolerance. However, there a lack genetic regarding whether how plants orchestrate dynamic assembly upon drought. By utilizing mutants with enhanced or decreased root hair densities, we find that regulators also affect induced changes. Rhizobiaceae key biomarker taxa affected by related mutants. We isolated sequenced 1479 associated microbes, confirmed several Rhizobium strains presented stress-alleviating activities. Metagenome, transcriptome metabolome studies further reveal multi-omic changes stress. knocked out an ornithine cyclodeaminase (ocd) gene in sp. 4F10, which significantly dampens its stress alleviating ability. Our integrated multi-omics confirm involvement host effects reshaping during drought, provide mechanistic insights into mediated protection. Plant confers fitness benefits integrating genetic, microbial approaches, this work reveals critical role developmental shaping microbiome.

Flavones enrich rhizosphere Pseudomonas to enhance nitrogen utilization and secondary root growth in Populus

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Feb. 7, 2025

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

Metabolomic Analysis of Maize Response to Northern Corn Leaf Blight

Metabolites, Journal Year: 2025, Volume and Issue: 15(2), P. 113 - 113

Published: Feb. 10, 2025

Background: As a major food crop, maize is highly susceptible to pathogenic bacteria, which greatly reduces its yield and quality. Metabolomics reveals physiological biochemical changes in organisms aids analyzing metabolic caused by various factors. Methods: This study utilized metabolomics examine maize’s after NCLB infestation, aiming uncover related pathways potential biomarkers. The metabolite measurements were performed during the silking stage. Results: PCA showed an obvious dispersion between treated untreated groups. OPLS-DA identified 1274 differential metabolites, with 242 being downregulated (mainly phenolics esters) 1032 upregulated (primarily organic acids, amino sugars, derivatives). KEGG annotation revealed 50 affected pathways, biosynthesis of secondary metab-olites acids was significantly enriched. Conclusions: We hypothesized that sugar metabolism, proline jasmonic acid synthesis are associated susceptibility. These findings provide critical insights into responses biotic stress, offering theoretical basis for future research on plant resistance mechanisms.
