Diatom Proteomics Reveals Unique Acclimation Strategies to Mitigate Fe Limitation [PDF]

open access: yes, 2015
Phytoplankton growth rates are limited by the supply of iron (Fe) in approximately one third of the open ocean, with major implications for carbon dioxide sequestration and carbon (C) biogeochemistry.

Effect of Metal Cations on Selenite Bioreduction by a Consortium of Halophilic/Halotolerant Bacteria and/or Yeast

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Evaluation the effects of potentially toxic co‐contaminating metal cations, including cadmium (Cd), lead (Pb), and Zinc (Zn), on the bioreduction of selenite by a consortium of halotolerant and halophilic bacteria and/or yeast. ABSTRACT Selenium oxyanion pollution in the environment, often originating from anthropogenic industrial activities, causes ...

Elucidating the Functional and Taxonomic Diversity of Soil Microbial Communities From Three Commercial Soybean Farms in South Africa

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Prior to inoculation of soybeans, South African soils contain no Bradyhizobia that nodulate and fix nitrogen in soybeans. Soybean cultivation with prolonged inoculation resulted in the establishment and dominance of Bradyrhizobia in three soybean farms in South Africa as revealed by a microbial community study using shotgun metagenomics. ABSTRACT Prior

The Seasonal and Spatial Patterns of Planktonic Bacterial and Fungal Community Structure and the Response to Environmental Factors in the Danjiangkou Reservoir, China

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
This study investigated the spatial and temporal distribution patterns of bacterial and fungal communities in the Danjiangkou Reservoir during dry season and wet season, revealing the mechanism by which seasonal variations drive changes in microbial community composition and function through their influence on the physicochemical properties of the ...

The Keto Functions of Heme d1 Are Introduced by NirF and NirC

open access: yesChemBioChem, Volume 27, Issue 10, 27 May 2026.
During heme d1 biosynthesis, the proteins NirF and NirC together catalyze the formation of dihydro‐heme d1, thereby introducing the unique keto functions of heme d1. In this paper, the development of an in vitro enzyme activity assay for NirF/NirC is described, which demonstrates the function of the two proteins for the first time.

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

open access: yesAdvanced Science, Volume 13, Issue 29, 22 May 2026.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

The Maize ZmbHLH118 Transcription Factor Regulates Vacuolar Nitrate Loading by the NO3− Transporter ZmCLCa

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.

Understanding the factors (salinity, nitrate, and carbon availability) and mechanisms that control N2O products and nitrate removal patterns in inland saline farmland ditches

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Denitrification, the microbial process by which nitrate (NO3−) in aquatic systems is converted to N2 and N2O, is widely recognized as an effective and environmentally friendly method for mitigating NO3− pollution in water bodies. However, the complex role of salinity, which could significantly influence the denitrification process, in salt ...
