Temporal dynamics of total and active root-associated diazotrophic communities in field-grown rice

Plant-associated nitrogen-fixing microorganisms (diazotrophs) are essential to host nutrient acquisition, productivity and health, but how host growth affects the succession characteristics of crop

Depth-related Variability of Biological Nitrogen Fixation and Diazotrophic Communities in Mangrove Sediments

Background: Nitrogen-fixing microorganisms (diazotrophs) provide biological available nitrogen and play a pivotal role in nitrogen cycling of mangrove sediments. However, most studies on

Diversity, function and assembly of mangrove root-associated microbial communities at a continuous fine-scale

The divergence in the diversity and function of root-associated microbial communities along a continuous fine-scale niche is revealed, thereby highlighting a strictly selective role of soil-root interfaces in shaping the fungal community structure in the mangrove root systems.

Rice Root-Associated Diazotrophic Community Succession is Driven by Growth Period Combined With Fertilization

Investigation of the succession of total and active diazotrophs in rhizosphere soil and rice roots under four fertilization treatments during three key growth periods found the alpha-diversity indices and complex of network structures of endophytic diazOTrophs increased at the vegetative stage.

Nitrogen Fertilization and Native C4 Grass Species Alter Abundance, Activity, and Diversity of Soil Diazotrophic Communities

Relationships between soil diazotrophic community and associated soil properties are revealed, adding to the understanding of the response of soil d Diazotrophs to N fertilization and grass species in native C4 grass systems.

Martelella alba sp. nov., isolated from mangrove rhizosphere soil within the Beibu Gulf

The phylogenomic tree based on the up-to-date bacterial core gene set indicated that the strain BGMRC 2036T form a clade formed with members of the genera Martelella, and it was namedMartelella alba sp.

Sugar and organic acid availability modulate soil diazotroph community assembly and species co-occurrence patterns on the Tibetan Plateau

It was found that the distribution of sugars and organic acids in the root-associated soils was significantly correlated with the richness of diazotrophs, and the presence of these two soil metabolites explains the variability indiazotrophic community compositions.



Diversity and Structure of Diazotrophic Communities in Mangrove Rhizosphere, Revealed by High-Throughput Sequencing

A comprehensive examination of the diversity and structure of microbial communities in the rhizospheres of three mangrove species was undertaken using high-throughput sequencing of the 16S rRNA and nifH genes, suggesting that diazotrophs potentially play an important role in biogeochemical cycles, such as those of nitrogen, phosphorus, sulfur, and potassium, in the mangroves ecosystem.

Anthropogenic impact on diazotrophic diversity in the mangrove rhizosphere revealed by nifH pyrosequencing

The increased abundance of Marinobacterium, which is a bioindicator of pollution, suggests that anthropogenic activity has a negative impact on the genetic diversity of diazotrophs in the mangrove rhizosphere.

Diversity of endophytic and rhizoplane bacterial communities associated with exotic Spartina alterniflora and native mangrove using Illumina amplicon sequencing.

The results provide clues to the isolation of functional bacteria and the effects of root-associated microbial groups on S. alterniflora invasions, including Methylococcales, Pseudoalteromonadacea, Clostridium, Vibrio, and Desulfovibrio which have the potential to affect the carbon, nitrogen, and sulfur cycles.

Ecology of heterotrophic dinitrogen fixation in the rhizosphere of mangrove plant community at the Ganges river estuary in India

SummaryHeterotrophic dinitrogen fixation in root associations of successional stages of the tropical mangrove plant community at the Ganges river estuary in India was investigated by excised-root

Bacterial Communities in the Rhizospheres of Three Mangrove Tree Species from Beilun Estuary, China

This study investigated the vertical distributions of rhizosphere bacteria from three mangrove species in Beilun Estuary, China using high throughput DNA pyrosequencing of the 16S rRNA gene to shed insights into biogeochemical transformations driven by bacteria in Rhizosphere sediments.

A consortium of non-rhizobial endophytic microbes from Typha angustifolia functions as probiotic in rice and improves nitrogen metabolism.

A long-term nitrogen deficiency response in the treated plants was elicited by the consortium improving N-uptake, assimilation and relative N-use efficiency of rice plants, which appeared to be at least one of the main strategies of plant growth promotion.

Multiple factors drive the abundance and diversity of diazotrophic community in typical farmland soils of China.

The findings suggest that diazotrophs have various activity and distribution in the three soil types, which played different roles on nitrogen input in agricultural soil in China, being driven by multiple environmental factors.
