Effectively utilizing aquatic plants to absorb nitrogen from water bodies and convert it into organic via assimilation enzyme activity reduces concentrations. This serves as a critical strategy for mitigating agricultural non-point source pollution in the Yellow River Basin However, emergent plants' rate mechanism of uptake different forms remain unclear. study determined rates, activities, root properties, photosynthetic parameters four plants, Phragmites australis, Typha orientalis, Scirpus validus, Lythrum salicaria, under five NH4+/NO3- ratios (9:1, 7:3, 5:5, 3:7, 1:9) using 15N hydroponic simulations. The results demonstrated that both form plant species significantly influenced rates plants. In with varying ratios, P. australis T. orientalis exhibited higher inorganic than S. validus L. increasing by 11.83-114.69% 14.07-130.46%, respectively. When ratio body was 9:1, reached its peak, which 729.20 μg·N·g-1·h-1 DW (Dry Weight). highest, reaching 763.71 DW. preferences significant environmental plasticity. At an preferred NO3--N, whereas salicaria favored NH4+-N. NH4+-N positively correlated glutamine synthetase glutamate synthase while NO3--N NR activity. These findings indicate processes these involve synergistic mechanisms adaptation physiological regulation, enabling more effective utilization water. Additionally, dehydrogenase (GDH), suggesting they are better adapted eutrophication GDH pathway. specific surface area plays crucial role regulating amount exerted greatest total impact on rate, followed traits enzymes. Therefore, there were interspecific differences response various forms. It is recommended prioritize use highly adaptable such irrigation area.

Linking ecological niches to bacterial community structure and assembly in polluted urban aquatic ecosystems

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Опубликована: Дек. 15, 2023

Introduction Bacterial communities play crucial roles in the functioning and resilience of aquatic ecosystems, their responses to water pollution may be assessed from ecological niches. However, our understanding such response patterns underlying mechanisms remains limited. Methods In this study, we comprehensively investigated effects on bacterial structure assembly within different niches, including water, sediment, submerged plant leaf surfaces, using a 16S high-throughput sequencing approach. Results Ecological niches had greater impact community diversity than pollution, with distinct enrichment unique dominant phyla This disparity extends general reduction α-diversity observed excluding surfaces. Additionally, changes composition should correlated predicted functions, given functions related biogeochemical cycling surface Moreover, study revealed diverse interaction among characterized by relatively simply associations sediments intricate or interconnected networks Furthermore, stochastic processes dominated column, whereas selective screening roots events increased deterministic processes. Discussion Overall, emphasizes importance shaping pollution. These findings improve complicated microbial have implications for ecosystem health.

Submerged plants can thrive entirely underwater, playing a crucial role in maintaining water quality, supporting aquatic organisms, and enhancing sediment stability. However, they face multiple challenges, including reduced light availability, fluctuating conditions, limited nutrient access. Despite these stresses, submerged demonstrate remarkable resilience through physiological biochemical adaptations. Additionally, their interactions with microbial communities are increasingly recognized as pivotal mitigating environmental stresses. Understanding the diversity of is for comprehending complex between environments. This research aims to identify screen microbes from plant samples capable producing 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase explore metagenomic analysis. Microbes were isolated screened ACC production, techniques, co-occurrence network analysis, used examine within communities. deaminase-producing significantly enhance metabolism under stress conditions. The identification culturable bacteria revealed that most belong genera Pseudomonas, Bacillus, Acinetobacter. A total 177 strains cultured, molecular revealing 79 reductant, 86 non-reductant, 12 uncultured strains. Among 162 activity, 50 tested positive. To further understand dynamics, collected both natural sources artificial pond reservoirs assess impact location on flood-associated microbiomes plants. Metagenomic analysis was conducted epiphytic endophytic samples. By exploring overall composition dynamics associated plants, this seeks deepen our understanding plant–microbe screening helped diverse activity amplicon sequencing paved way towards identifying shaping microbiome microbes. Co-occurrence highlighted intricate Notably, observed plant-associated across different locations, distinct variations populations identified
