Abstract Research on the composition and diversity of rhizosphere microbial communities different plant species can help to identify important functional groups or potentials, which is great significance for vegetation restoration ecological reconstruction. To provide scientific basis management mountain ecosystem, pattern bacterial community was investigated using 16S rRNA high-throughput sequencing method among host plants (Cirsium japonicum, Artemisia annua, Descurainia sophia, Lepidium apetalum, Phlomis umbrosa, Carum carvi) in Tomur Peak National Nature Reserve, China. The results showed that richness bacteria were highest lowest apetalum. Proteobacteria, Acidobacteriota, Actinobacteria common dominant phyla, Sphingomonas predominant genera. Furthermore, there some specific genera plants. relative abundance non-dominant varied species. Canonical correspondence analysis indicated available (AK), total phosphorus (TP), potassium (TK), soil organic matter (SOM) main drivers structure. Based PICRUSt prediction, all samples encompass six primary metabolic pathways 47 secondary pathways. major (with a gene sequences > 3%) include 15 categories. Co-occurrence network revealed differences interactions modules, with microorganisms exhibiting distinct advantages. This study elucidates distribution patterns ecosystems, provides theoretical guidance protection based microbiome.

Abstract Epiphytic bacteria constitute a vital component of aquatic ecosystems, pivotal in regulating elemental cycling. Despite their significance, the diversity and functions epiphytic bacterial communities adhering to various submerged macrophytes remain largely unexplored. In this study, we employed metagenomic approach investigate function associated with six macrophytes: Ceratophyllum demersum , Hydrilla verticillata Myriophyllum verticillatum Potamogeton lucens Stuckenia pectinata Najas marina . The results revealed that predominant species for each plant type included Pseudomonas spp., Microbacterium Stenotrophomonas rhizophila Multiple comparisons linear discriminant analysis effect size indicated significant divergence community composition among macrophytes, 0.3–1% uniquely identified. richness S. significantly differed from both C.

The hyperarid core of the Atacama Desert represents one most intense environments on Earth, often being used as an analog for Mars regolith. area is characterized by extremes in climate (e.g., temperature, humidity, UV irradiation) and edaphic factors hyper-salinity, high pH, compaction, perchlorates, low moisture, phosphorus organic matter).

Within habitat it captures windblown sand leading formation unique structures generation above-ground phyllosphere soil.

This study presented a comprehensive analysis of the microbial ecology in water diversion rivers (WDRs) source area East Route South-to-North Water Diversion Project (ER-SNWDP) China across various periods. Proteobacteria, Chloroflexi, Acidobacteriota, and Bacteroidota were identified as dominant phyla river sediment. During wet period, communities exhibited highest richness, biodiversity, most intense antagonistic relationships compared to those dry normal Generally, network predominantly existed symbiotic models characterized by mutual benefit symbiosis throughout all co-occurrence was found be complex, with OTUs showing closest interconnections. The mechanisms governing community diversity, succession, biogeography spatial turnover species stochastic processes. A more pronounced impact processes on assemblages observed during or periods than period.

Particular frost patterns on natural leaves had prompted Yao et al. [Y. al ., Proc. Natl. Acad. Sci. U.S.A. 117 , 6323–6329 (2020)] to investigate the underlying physics. Their work revealed why corrugated surfaces ice forms crests and dries out adjacent grooves. In absence of frost, in contrast, grooves tend constitute niches a leaf where microorganisms are less limited by moisture than other locations. Here, we show that able nucleate before it can modify frosting pattern their advantage. This ability might drive cold arid environments association between certain plants.
