Integrated rice-fish farming has emerged as a novel agricultural production pattern to address global food security challenges. Aiming determine the optimal, scientifically sound, and sustainable stocking density of red claw crayfish (Cherax quadricarinatus) in an integrated rice-crayfish system, we employed Illumina high-throughput 16S rRNA gene sequencing evaluate impact different densities on composition, diversity, function, co-occurrence network patterns soil bacterial communities. The high reduced diversity evenness community during mid-culture stage. Proteobacteria, Actinobacteria, Chloroflexi most prevalent phyla throughout experimental period. Low initially boosted relative abundance Actinobacteria paddy soil, while did so middle final stages. There were 90 distinct functional groups identified across all samples, with chemoheterotrophy aerobic being abundant. favored these groups, whereas enhanced their abundances later stages cultivation. Medium led more complex mid- culture period showed significant correlations communities, total nitrogen (TN) phosphorus (TP) concentrations emerging primary factors contributing alterations In summary, our findings demonstrated that significantly impacted microbiomes environmental at varying densities. Our study contributed theoretical insights into profound various communities soils.

Background Rhizosphere soil microorganisms, as the second genome of plants, play an important role in formation secondary metabolites medicinal plants and are one key factors authenticity materials. Methods In this paper, rhizosphere soils Gentiana scabra Bunge from six producing areas Liaoning Province were taken research objects. Through high-throughput sequencing technology, with help PLS-DA RDA, impacts microorganisms environmental on quality G. explored depth. Results Alpha diversity shows that bacterial communities varies significantly, while regularity fungi is weak; beta samples different can be effectively grouped according to community structure. LDA effect differential species bacteria vary among areas. Indicator random forest analysis show Sphingomonas Subgroup_2 main indicator high-content group, which increase evenness microbial maintain or enhance diversity. The fungal relatively weak. Functional metagenomic functions similar but relative abundances different. closely related metabolism diverse environments, biosynthesis metabolites, metabolic pathways, etc.; mainly lichen parasite, plant saprotroph, ericoid mycorrhizal.

Seasonality and Vertical Structure of Microbial Communities in Alpine Wetlands

Microorganisms, Journal Year: 2025, Volume and Issue: 13(5), P. 962 - 962

Published: April 23, 2025

The soil microbial community plays a crucial role in the elemental cycling and energy flow within wetland ecosystems. temporal dynamics spatial distribution of communities are central topics ecology. While numerous studies have focused on structures at low altitudes, diversity across seasons depths their environmental determinants remain poorly understudied. To test seasonal variation with contrasting fluxes greenhouse gases, total 36 samples were collected from different Namco Tibetan Plateau four seasons. We found significant bacterial composition, most pronounced Winter, but not archaea. In particular, Proteobacteria decreased by 11.5% Winter compared other (p < 0.05). alpha showed hump-shaped patterns lower whereas archaea no depths. A PERMANOVA further revealed differences structure between three addition, archaeal differed surface (0–5 cm) deeper (5–30 soils 0.01). Redundancy analysis that nitrogen, phosphorus, organic carbon significantly influenced bacteria Furthermore, moisture content temperature strongly affected 0.001).

Association between plant microbiota and cadmium uptake under the influence of microplastics with different particle sizes

Environment International, Journal Year: 2024, Volume and Issue: 190, P. 108938 - 108938

Plant microbiota are an important factor impacting plant cadmium (Cd) uptake. However, little is known about how affects the Cd uptake by plants under influence of microplastics (MPs) with different particle sizes. In this study, bacterial structure and assembly in rhizosphere endosphere pakchoi were analyzed amplicon sequencing 16S rRNA genes sizes polystyrene (PS-MPs) combined treatments. Results showed that there no significant differences observed shoot endophytes among compared to treatment, larger-sized PS-MPs (2 20 μm) significantly increased community diversity altered structural composition bacteria root endophytes, while smaller-sized (0.2 did not. Under treatment PS-MPs, niche breadth increased. And also maintained stability complexity co-occurrence networks, reduced them. Furthermore, addition larger size decreased proportion homogeneous section, drift endophytic assembly. The role MPs was opposite. Using random forest equation models, study found can promote colonization specific taxa, such as Brevundimonas, AKAU4049, SWB02, Ellin6055, Porphyrobacter, Sphingorhabdus, Rhodobacter, Erythrobacter, Devosia some other belonging Alphaproteobacteria, endosphere. these taxa may induce formation biofilms roots, immobilize heavy metals through oxidation processes, growth, thereby reducing pakchoi. findings provide insights into microbial mechanisms underlying on
