Interação entre fungos micorrízicos arbusculares e bactérias diazotróficas em trigo Interaction between arbuscular mycorrhizal fungi and diazotrophic bacteria in wheat plants

Pesquisa Agropecuária Brasileira, 2007
O objetivo deste trabalho foi avaliar o efeito da inoculação de dois novos isolados de bactérias diazotróficas endofíticas e da interação destas bactérias com fungos micorrízicos arbusculares (FMAs), na cultura do trigo.

Soil organic matter is essential for colony growth in subterranean termites

Scientific Reports, 2021
Intrinsic dinitrogen (N2) fixation by diazotrophic bacteria in termite hindguts has been considered an important pathway for nitrogen acquisition in termites.

Does Slight Soil Acidification Negatively Affect Diazotrophic Bacterial Community in Paddy Field? A Regional-Scale Study

Ecosystem Health and Sustainability
Diazotrophic bacteria are eco-friendly alternatives for reducing chemical N fertilizer use. Yet, their responses to soil acidification from excessive fertilization in paddy ecosystems remain unclear. To elucidate this issue, we compared the structure and

Iron Homeostasis in Azotobacter vinelandii

Biology, 2023
Iron is an essential nutrient for all life forms. Specialized mechanisms exist in bacteria to ensure iron uptake and its delivery to key enzymes within the cell, while preventing toxicity.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

Growth promotion of Guinea grass by diazotrophic bacteria

Pesquisa Agropecuária Tropical, 2019
The Panicum maximum species (cv. Mombaça) is a forage plant well adapted to the different edaphoclimatic conditions found in Brazil; however, it requires high nitrogen fertilizer doses to ensure high yields.

Plant species are more important to bacterial community composition than seeding ratio in a pea‐canola intercropping system

PLANTS, PEOPLE, PLANET, EarlyView.
Demand for agricultural land has increased due to rising demand for food, potentially leading to expansion into previously untouched habitats, which threatens refugia of native plants. We aimed to provide insight into how variation in seeding ratio may impact soil bacterial communities in a pea‐canola intercropping system, potentially altering crop ...

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...
