A short‐term flood, implemented in a field experiment with sprinkler irrigation in maize production systems, increased soil moisture levels and reduced autoclaved citrate extractable protein, an indicator of soil biological health that reflects organically bound soil nitrogen, and also corresponded to greater differential abundance of soil bacterial ...

ABSTRACT The phyllosphere, the aboveground interface between plant leaves and their microbial residents, plays a vital yet underappreciated role in crop productivity. While root‐ and soil‐associated microbiomes are well‐studied, the ecological assembly and yield‐related effects of host‐mediated phyllosphere microbial communities remain largely ...

Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...

Hi‐C sequencing was used to link viral sequences with microbial metagenome assembled genomes in the largely uncultivated waters of an oxygen‐deficient zone's secondary chlorophyll maximum within the Eastern Tropical North Pacific Ocean. ABSTRACT Oxygen‐deficient zones (ODZs) influence global nitrogen cycling as key sites for the removal of bioavailable

Despite intensive microbiological characterization of soda lake microbial communities, no culturable representatives from the phylum Planctomycetota have been isolated from these haloalkaline habitats. In the context of studying polysaccharide utilization by soda lake microbial communities, we used polysaccharide hyaluronic acid as enrichment substrate

Novel candidate taxa contribute to key metabolic processes in Fennoscandian Shield deep groundwaters. [PDF]
The continental deep biosphere contains a vast reservoir of microorganisms, although a large proportion of its diversity remains both uncultured and undescribed.

This study investigated the interplay between fluid geochemistry and microbial diversity in the shallow‐water hydrothermal vents of the gulf of Naples, Italy. We found that hydrothermal fluid chemistry and the geological settings where the vents are hosted play a key role in shaping microbial distribution.

Activity‐Informed Network Analysis Reveals Keystone Microbes Shaping Freshwater Ecosystem Function
Graphical abstract illustrating the workflow and key findings of this study. We first applied SPIEC‐EASI to metagenomic abundance data to construct microbial co‐occurrence networks and selected the top 15 MAGs based on degree centrality. We then used CARlasso to detect relationships between the top MAGs and environmental features.

Seasonal dynamics of prokaryotic communities in Kongsfjorden were driven by contrasting hydrographic conditions in 2019 and 2020. Atlantification enhanced prokaryotic diversity and interactions in 2019, while sea ice and glacial runoff in 2020 reduced surface diversity and network complexity, underscoring Arctic prokaryotic sensitivity to environmental

A century of research on Planctomycetota bacterial phylum, previously known as Planctomycetes
Abstract 100 years after Planctomycetes were discovered and fifty years since the first isolate was successfully cultured, this bacterial phylum remains enigmatic in many ways. In the last few decades, a significant effort to characterize new isolates has resulted in over 150 described species, allowing a more comprehensive analysis ...
