Alley Cropping Can Potentially Alter the Nitrogen and Carbon Soil Cycles and Increase the Abundance of Beneficial Bacteria in a Mediterranean Citrus Orchard

Journal of Sustainable Agriculture and Environment, Volume 4, Issue 2, June 2025.
ABSTRACT Monocrop of mandarin leading to reduced soil biodiversity and functionality that must be changed to a sustainable agriculture practice such as alley cropping. In this study an attempt has been made to assess how two different alley cropping strategies promote soil bacterial diversity, microbial activities and the abundance of beneficial ...

Genome‐wide association study and BSR‐seq identify nitrate reductase–related genes in rice landraces (Oryza sativa L.)

The Plant Genome, Volume 18, Issue 2, June 2025.
Abstract Nitrogen (N) is an essential nutrient for rice (Oryza sativa L.) growth and development. However, the lower nitrogen use efficiency (NUE) results in an N fertilizer surplus, which causes many environmental problems. In this study, genome‐wide association studies were used to detect nitrate reductase (NR)‐related loci in 419 rice landraces ...

Distinguishing the Isotopic Signals of Nitrate Assimilation and Denitrification Along the GEOTRACES GP15 Pacific Meridional Transect

Journal of Geophysical Research: Oceans, Volume 130, Issue 6, June 2025.
Abstract The biogeochemical processes shaping the fluxes of nitrogen (N) in the tropical to subarctic Pacific are illuminated by nitrate isotope ratios (δ15N and δ18O) along the GEOTRACES GP15 section. In the equatorial and tropical Pacific, nitrate δ15N and δ18O are 2–4‰ higher in the thermocline than in deeper waters.

Variations in abundance and community composition of denitrifying bacteria during a cyanobacterial bloom in a eutrophic shallow lake in China

Journal of Freshwater Ecology, 2017
Although cyanobacterial blooms can change microbial communities, it is still unclear what impact such harmful blooms will have on denitrifying bacteria, the drivers of the removal of excessive nitrogen from water.

Superoxide reductase from Desulfoarculus baarsii: reaction mechanism and role of glutamate 47 and lysine 48 in catalysis [PDF]

Biochemistry, American Chemical Society, 2001, pp.5032-40, 2015
Superoxide reductase (SOR) is a small metalloenzyme that catalyzes reduction of O(2)(*)(-) to H(2)O(2) and thus provides an antioxidant mechanism against superoxide radicals. Its active site contains an unusual mononuclear ferrous center, which is very efficient during electron transfer to O(2)(*)(-) [Lombard, M., Fontecave, M., Touati, D., and Nivi ...

Microbial Responses to Micronutrient Amendments in Oxygenated and Deoxygenated Waters of the Arabian Sea

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Microcosm experiments and 16S rRNA amplicon sequencing show that micronutrients (Zn, Fe, Co) or their combination (Zn + Fe + Co) significantly influence nutrient concentrations and microbial dynamics in both oxygenated (73 m) and deoxygenated (200 m) waters of the Arabian Sea.
