Autotrophic and symbiotic diazotrophs dominate nitrogen-fixing communities in Tibetan grassland soils

, 2018
Biological nitrogen fixation, conducted by soil diazotrophs, is the primary nitrogen source for natural grasslands. However, the diazotrophs in grassland soils are still far from fully investigated.

Trace Element Bioavailability Shapes Bacterial Communities and Biological Nitrogen Fixation in Paddy Soils

Nitrogen
Biological nitrogen fixation (BNF) is a key nitrogen source in paddy soils, yet its spatial variability remains poorly understood. In this study, we conducted a 90-day 15N2 labeling experiment using soils from seven paddy fields in Zhejiang Province ...

Diazotrophic bacteria in star flowers

Bioscience Journal, 2012
This study evaluated the occurrence and density of associative diazotrophic bacteria in the rhizosphere, collar, roots and leaves of Syngonanthus elegans (Bong) Ruhland (Goldenfoot) and Syngonanthus aciphyllus (Mini-skirt). These species are able to grow in poor soils. Five samples, with 25 plants both of S. elegans and S.

Effect of Hydrolytic Enzymes Production by Diazotrophs and Urea Fertilization on Root Colonization and Growth of Rice (Oryza Sativa L.) [PDF]

, 2010
Production of hydrolytic enzyme by diazotrophs and their association with rice plant may increase the N2-fixing activity and subsequently plant growth. The ability to produce hydrolytic enzymes is an important mechanism of diazotrophs to enter the plant ...

Keystone rhizospheric diazotrophs may promote the pioneer plant growth in mine tailings

Soil Security
Nitrogen (N) shortage often hinders the bioremediation of mining-generated tailings. For pioneer plants living in mine tailings, biological N fixation (BNF) is an essential source of N.

Impacts of Managed Vegetation Restoration on Arbuscular Mycorrhizal Fungi and Diazotrophs in Karst Ecosystems

The crucial functional arbuscular mycorrhizal fungi (AMF) and diazotrophs play pivotal roles in nutrient cycling during vegetation restoration. However, the impact of managed vegetation restoration strategies on AMF and diazotroph communities remains ...
