Combined Application of High-Throughput Sequencing and Metabolomics to Evaluate the Microbial Mechanisms of Plant-Growth-Promoting Bacteria in Enhancing the Remediation of Cd-Contaminated Soil by Hybrid Pennisetum

Agronomy, Journal Year: 2024, Volume and Issue: 14(10), P. 2348 - 2348

The contamination of soil with the heavy metal cadmium (Cd) is increasingly prominent and severely threatens food security in China. Owing to its low cost, suitable efficacy, ability address shortcomings plant remediation by enhancing plants take up Cd, plant–microbe combination technology has become a research hotspot pollution remediation. A pot experiment was performed examine effects inoculation plant-growth-promoting bacterium Brevibacillus sp. SR-9 on biomass, Cd accumulation, nutrients hybrid Pennisetum. purpose this study determine how alleviates stress caused contamination. High-throughput sequencing metabolomics were used bacterial community composition microbial metabolic functions associated results suggest that mutation effectively stress, leading increased biomass accumulation aboveground root weight 12.08% 27.03%, respectively. Additionally, sections roots 21.16% 15.50%, Measurements physicochemical properties revealed strain slightly levels available phosphorus, total nitrogen, potassium. DNA implantation modified increasing average number Actinobacteria Bacillus. nitrogen content positively correlated abundance, phosphorus level, level. Metabolomic analysis affected abundance metabolites, 59 differentially abundant metabolites identified (p < 0.05). Among these, 14 presented whereas 45 decreased abundance. Fourteen pathways enriched these metabolites: folate resistance pathway, ABC transporter D-glutamine D-glutamic acid metabolism, purine pyrimidine metabolism. potassium, nitrogen. According correlation analyses, development Pennisetum are strongly which also impact certain populations. This work altering makeup communities their processes, bacteria promote can mitigate Cd. These findings reveal microbiological mechanisms through increase present contaminated soils.

Microplastics Alter Cr Accumulation and Fruit Quality in Cr(Vi) Contaminated Soil-Cucumber System During the Lifecycle: Insight from Rhizosphere Bacteria and Root Metabolism

Published: Jan. 1, 2023

Both microplastics and Cr(VI) potentially threaten soil crop, but little is known about their interaction in the soil-plant system. This study investigated effect mechanism of polyethylene (PE), polyamide (PA), polylactic acid (PLA) on Cr bioaccumulation toxicity a contaminated soil-cucumber system during lifecycle. The results show that had greater accumulation cucumber roots, stems, leaves than fruits. PE increased PA PLA decreased cucumber. Microplastics, especially high-dose, small, aged microplastics, exacerbated effects accumulated fresh weight fruit yield. nutrient contents fruits except soluble sugars were reduced by microplastics. random forest regression model shows microplastic type was most important factor causing changes for addition. Under co-exposure, bacteria could simultaneously tolerate stress degrade enriched rhizosphere soil. partial least squares path beneficial bacterial community growth. alleviated adverse root metabolism.
