Rhizophagus intraradices improves soybean microbiome niche under saline-alkaline stress across critical growth stages

Project description:BackgroundSoil salinization and alkalization severely threaten soybean growth and yield. Arbuscular mycorrhizal fungi (AMF), specifically Rhizophagus intraradices (Ri), enhance stress tolerance and soil quality, yet their mechanisms in regulating microbial-metabolite interactions during critical soybean growth stages remain unclear.ResultsThis research employed partitioned (rhizosphere and hyphosphere) pot experiments in natural saline-alkaline soil, integrating high-throughput sequencing and untargeted metabolomics to analyze Ri effects on microbial communities and metabolic functions at branching (V5), pod development (R4), and mature pod (R8) stages. Results revealed V5 stage for Ri to activate host resistance, R4 for hyphal expansion (density 21.13 m/g), enhancing nutrient uptake, and R8 stage for increased spore and glomalin-related soil protein (GRSP) secretion to alleviate stress. Ri differentially regulates bacterial-fungal networks, enriching biomarker and driving stochastic microbial assembly. Ri shifted bacterial assembly toward stochasticity and enriched biomarkers. Bacterial richness peaked under RiRR4 (+Ri, R4 rhizosphere; +27.06% vs CRR4). Fungal assembly showed a different trend, peaking under RiRV5 (+Ri, V5 rhizosphere; +39.75% vs CRV5). Ri enhanced plant resistance and soybean growth via bacterial diversity in rhizosphere soil. Metabolomics identified phenylalanine metabolism as a core Ri-regulated pathway under saline-alkaline stress, facilitating carbon-nitrogen cycling and secondary metabolite accumulation.ConclusionsThis research reveals how Ri coordinates microbial and metabolic processes to enhance saline-alkaline resistance in soybean.

Bacterial single-cell RNA sequencing captures biofilm transcriptional heterogeneity and differential responses to immune pressure

Project description:Biofilm formation is an important mechanism of survival and persistence for many bacterial pathogens. These multicellular communities contain subpopulations of cells that display vast metabolic and transcriptional diversity along with high recalcitrance to antibiotics and host immune defenses. Investigating the complex heterogeneity within biofilm has been hindered by the lack of a sensitive and high-throughput method to assess stochastic transcriptional activity and regulation between bacterial subpopulations, which requires single-cell resolution. We have developed an optimized bacterial single-cell RNA sequencing method, BaSSSh-seq, to study Staphylococcus aureus diversity during biofilm growth and transcriptional adaptations following immune cell exposure.

Melatonin enhances plant growth and abiotic stress tolerance in soybean plants

Project description:Melatonin is a well-known agent that plays multiple roles in animals. Its possible function in plants is less clear. In the present study, we tested the effect of melatonin (N-acetyl-5-methoxytryptamine) on soybean growth and development. Both spraying of leaves and seed-coating with melatonin significantly promoted soybean growth as judged from leaf size and plant height. This enhancement was also observed in soybean production and their fatty acid content. Melatonin increased pod number, seed number and seed weight. However, the 100-seed weight was not influenced by melatonin application. Melatonin also improved soybean tolerance to salt and drought stresses. Transcriptome analysis revealed that melatonin up-regulated the expression of many genes and alleviated the inhibitory effects of salt stress on gene expressions. Further detailed analysis of the affected pathways documents that melatonin likely achieved its promotional roles in soybean through enhancement of genes involved in cell division, photosynthesis, carbohydrate metabolism, fatty acid biosynthesis and ascorbate metabolism. Our results demonstrate that melatonin has significant potential for improving of soybean growth and seed production. Further study should uncover more about the molecular mechanisms of melatonin’s function in soybeans and other crops.

Deep sequencing of small RNAs from different tissues in soybean

Project description:Analysis of flanking genomic sequences of unique small RNAs enabled identification of 419 miRNAs. Expression analysis revealed that miRNAs were differentially expressed in different tissues and development stages. Prediction of the miRNA target genes suggested that they are involved in important processes in soybean growth and development. Most conserved soybean miRNAs guide the cleavage of conserved genes. Our study significantly increased the number of known conserved and non-conserved miRNAs in soybean. Our description of soybean miRNAs can be used for functional characterization.
