Ecological significance of Candidatus ARS69 and Gemmatimonadota in the Arctic glacier foreland ecosystems

Applied Microbiology and Biotechnology, Journal Year: 2024, Volume and Issue: 108(1)

Published: Jan. 15, 2024

Abstract The Gemmatimonadota phylum has been widely detected in diverse natural environments, yet their specific ecological roles many habitats remain poorly investigated. Similarly, the Candidatus ARS69 identified only a few habitats, and literature on metabolic functions is relatively scarce. In present study, we investigated significance of phyla Ca. Arctic glacier foreland (GF) ecosystems through genome-resolved metagenomics. We have reconstructed first high-quality metagenome-assembled genome (MAG) belonging to 12 other MAGs from three different GF samples. further elucidated these two groups phylogenetic lineage function phylogenomic pangenomic analysis. analysis showed that all potentially belonged novel species. consist about 8296 gene clusters, which 8% single-copy core genes ( n = 980) were shared among them. study also revealed potential role associated with carbon fixation, denitrification, sulfite oxidation, reduction biochemical processes ecosystems. demonstrates widespread distribution classes across wide ranges functions, including polar region. Key points • Glacier act as laboratory microbial community structure. 13 genomes soil All species processes. found participate fixation denitrification

Light Intensity Modulates the Functional Composition of Leaf Metabolite Groups and Phyllosphere Prokaryotic Community in Garden Lettuce (Lactuca sativa L.) Plants at the Vegetative Stage

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(3), P. 1451 - 1451

Published: Jan. 25, 2024

Light intensity primarily drives plant growth and morphogenesis, whereas the ecological impact of light on phyllosphere (leaf surface endosphere) microbiome is poorly understood. In this study, garden lettuce (Lactuca sativa L.) plants were grown under low, medium, high intensities. High remarkably induced leaf contents soluble proteins chlorophylls, it reduced nitrate. comparison, medium exhibited highest sugar, cellulose, free amino acids. Meanwhile, resulted in significant changes composition functional genes but not taxonomic compositions prokaryotic community (bacteria archaea) phyllosphere.

Differentiation and Interconnection of the Bacterial Community Associated with Silene nigrescens Along the Soil-To-Plant Continuum in the Sub-Nival Belt of the Qiangyong Glacier

Plants, Journal Year: 2025, Volume and Issue: 14(8), P. 1190 - 1190

Published: April 11, 2025

Plant microbiomes provide significant fitness advantages to their plant hosts, especially in the sub-nival belt. Studies date have primarily focused on belowground communities this region. Here, we utilized high-throughput DNA sequencing quantify bacterial rhizosphere soil as well root and leaf endosphere compartments of Silene nigrescens uncover differentiation interconnections these along soil-to-plant continuum. Our findings reveal that exhibit notable variation across different compartment niches: soil, endosphere, endosphere. There was a progressive decline diversity, network complexity, modularity, niche breadth from further Conversely, both host selection effect stability showed an increasing trend. Total nitrogen total potassium emerged crucial factors accounting for observed differences diversity composition, respectively. Additionally, 3.6% amplicon sequence variants (ASVs) were shared Source-tracking analysis revealed community migration among compartments. The genera Pseudomonas, IMCC26256, Mycobacterium, Phyllobacterium, Sphingomonas constituted core microbiome. These taxa are all three niches function key connector species. Notably, Pseudomonas stands out predominant taxon bacteria, with being most factor influencing its relative abundance. deepen our understanding assembly principles ecological dynamics microbiome belt, offering integrated framework study.
