Metagenomic analysis reveal the phytoremediation effects of monocropping and intercropping of halophytes Halogeton glomeratus and Suaeda glauca in saline soil of Northwestern China

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: Feb. 18, 2025

Planting halophytes is a widely used method of phytoremediation for saline soils. The succulent Halogeton glomeratus and Suaeda glauca are remediation soil in the arid region Northwestern China. However, whether intercropping H. S. can increase improvement effect yet to be proved. Therefore, this study analyzed three planting modes: monocropping (Hg), (Sg), (Hg||Sg). These were applied field experiments, with biomass physicochemical properties measured each treatment, mechanism was using macrogenomics. After harvesting after one season, Hg treatment had highest dry total dissolved salt content reduced; correspondingly, pH decreased organic matter increased. results showed that Actinobacteria, Acidobacteria Proteobacteria dominant phylum under four treatments. This suggests more capable producing microorganisms favorable remediation. Thus, effective strategy zone

Taxonomic and functional β-diversity patterns reveal stochastic assembly rules in microbial communities of seagrass beds

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 28, 2024

Microorganisms are important members of seagrass bed ecosystems and play a crucial role in maintaining the health seagrasses ecological functions ecosystem. In this study, we systematically quantified assembly processes microbial communities fragmented beds examined their correlation with environmental factors. Concurrently, explored relative contributions species replacement richness differences to taxonomic functional β-diversity communities, investigated potential interrelation between these components, assessed explanatory power The results suggest that stochastic dominate community assembly. Taxonomic governed by replacement, while for β-diversity, contribution slightly outweighs processes. A weak but significant ( p < 0.05) exists two components taxonomy functionality, almost no observed This implies taxonomy, convergence redundancy within communities. Environmental factors insufficient explain differences. conclusion, is patterns provide new insights evidence better understanding rules. has implications conservation management beds.

Microencapsulated Microbial Seed Coating Could Improve Soil Environment and Maize Grain Yield in Saline Soil

Plants, Journal Year: 2024, Volume and Issue: 13(22), P. 3139 - 3139

Published: Nov. 7, 2024

Soil salinization is one of the major challenges for modern agriculture, posing a great threat to soil health and food security. Field experiments were conducted evaluate effect seed coating on environment maize growth in saline soils. Three treatments applied seeds: with microencapsulated microbial agent (ME), only (MB), no (CK). High-throughput sequencing bacterial fungal 16S ITS rRNA genes was performed using Illumina HiSeq platform analyze effects these diversity community structure. Additionally, influence different endogenous hormones yield investigated. It found that led decreases pH electrical conductivity (EC), while increasing content available phosphorus. This improved diversity, significantly relative abundance main bacteria genera,

Claroideoglomus etunicatum affects the diversity and composition of the rhizosphere microbial community to help tall fescue resist saline-alkali stress

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 21, 2024

Arbuscular mycorrhizal fungi (AMF) and plant rhizosphere microbes reportedly enhance tolerance to abiotic stresses promote growth in contaminated soils. Soil salinization represents a severe environmental problem. Although the influence of AMF phytoremediation saline-alkali soils has been fully demonstrated, underlying interactive mechanisms between are still unclear. A greenhouse pot experiment was conducted explore effects (Claroideoglomus etunicatum) on tall fescue promotion microbial community We aimed investigate mechanism affecting under stress conditions via interactions with microbes. found that significantly increased shoot, root total biomass soil. diversity bacterial fungal communities, altered their composition: for bacteria, inoculation treatment (M+) had higher relative abundance Proteobacteria, Actinobacteriota Firmicutes, lower Acidobacteriota Chloroflexi than no application (M-); fungi, M + Ascomycota Mortierellomycota M- treatment. Furthermore, structural equation modeling (SEM) revealed promoted mainly by regulating soil communities. This study provides theoretical basis improving adaptation through management practices.

Saline soil is one of the important environmental problems facing world. Planting halophytes a widely used method phytoremediation for saline soils. The succulent Halogeton glomeratus and Suaeda glauca are remediation in arid region Northwestern China. However, whether intercropping H. S. can increase improvement effect yet to be proved, there no comparative reports on monocropping intercropping. Therefore, this study analyzed three planting modes: (Hg), (Sg), (Hg||Sg). These were applied field experiments, with biomass physicochemical properties measured each treatment, mechanism was using macrogenomics. After harvesting after season, Hg treatment had highest dry 9.6 t ha−1. Soil total dissolved salt content reduced by 1.138, 0.744, 0.923 g/kg Hg, Sg, Hg||Sg treatments, respectively; correspondingly, pH decreased 0.52, 0.19, 0.34 organic matter increased 4.124, 1.113, 2.563 g/kg.

Hongdoukou plant (Alpinia galanga Willd.) is a perennial herbaceous that usually has stable microflora living in the inter-root and stem leaf tissues, which assists host normal growth development. The bacterial wilt disease had been investigated planting bases of A. galanga, was new soil-borne infected by pathogenic bacteria (Ralstonia solanacearum (Smith) Yabuuchi et al.), disrupts galanga-microbe-soil microecological balance. For this reason, it important to study changes community composition diversity endophytic fungi healthy diseased (HDK_J HDK_B), mine active fungal resources order lay foundation for exploring functional microbial communities artificial synthesis. All experimental materials were from clusters traditional areas Guangdong Province. isolated stems leaves separated tissue blocks cultured PDA medium. colonization rate (CR) calculated, strains amplified PCR with ITS1/ITS4 genes as molecular markers, identify species, analyze HDK_J HDK_B, indexes included: relative segregation frequency (SF), abundance (RA) plotted ggplot2 under R language, Shannon-Wiener index (H′), Simpson (D), Margalef richness (R) Pielou uniformity (J), finally, phylogenetic tree constructed MEGA.
