Identification of Sources of Dissolved Organic Matter Using Multi‐Isotope Approach

open access: yesCLEAN – Soil, Air, Water, Volume 54, Issue 7, July 2026.
• A precise and multi‐isotope method was developed using solid phase extraction (SPE) and Element Analyzer – Isotope Ratio Mass Spectrometry (EA‐IRMS) to characterize the dissolved organic matter (DOM). • The DOM extraction and elution methods were standardized for natural waters containing as low as 0.5 mg DOM. • The extraction efficiencies range from

Photosynthetic primary production in the Mesoproterozoic

open access: yesNew Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

CIA5 and its interacting metal‐binding GTPase ZNG3 are degraded by the proteasome in Zn deficiency

open access: yesThe Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY Carbon and zinc (Zn) metabolism are tightly connected in phototrophs, as carbonic anhydrases critical for CO2 assimilation are highly abundant Zn enzymes. The eukaryotic green alga Chlamydomonas (Chlamydomonas reinhardtii) maintains efficient phototrophic growth in ambient or low CO2 environments by establishing a carbon concentrating mechanism

Stress‐Resistant Symbiodiniaceae and Diverse Bacterial Communities Promote Coral Persistence in Variable, Multi‐Stressor Environments

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Corals living in multi‐stressor bays in Curaçao maintain stress‐tolerant symbiotic algae and specialized bacterial communities in comparison to those in nearby reefs. These findings provide insight into how Caribbean coral holobionts persist in extreme and marginal conditions and may respond under future environmental conditions.

Co‐inoculation with Bacillus and exopolysaccharide Cp2‐exopolysaccharides promotes salt stress tolerance and productivity in alfalfa

open access: yesGrassland Research, Volume 5, Issue 2, Page 119-131, June 2026.
Co‐inoculation with Bacillus and Cp2‐Exopolysaccharides (EPS) promotes salt stress tolerance and productivity in alfalfa. CK1 (control1): distilled water, DN2: Bacillus strain DN2, EPS: Exopolysaccharide, CK2 (control2): 100 mmol·L‐1 NaCl, S: Salt. Abstract Background Alfalfa is one of the most important forage crops in the world, and its performance ...

The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, Volume 5, Issue 3, Page 312-324, June 2026.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.
