ABSTRACT The relationship between soil microbiome stability and diversity remains a topic of debate. Our study aims to investigate the in different wetland types invaded by Spartina alterniflora reveal mechanisms driving functional influences on this during later‐stage development S. invasion system. To investigated structure, diversity, traits bacteria associated with their impact bacteriome we conducted 16S rRNA sequencing soils from two wetlands dominated invasive plant at growth stages, situated temperate (salt marsh wetland) subtropical (mangrove regions, assessed its factors. Subsequently, analyzed environmental bacterial changes sites constructed co‐occurrence networks among taxonomic groups traits. differences late‐stage ‐invaded systems suggest that communities higher tend exhibit greater stability. Keystone genera play both direct indirect roles regulating stability, all belong dominant phyla. Furthermore, biological factors significantly outweigh nonbiological In contrast, core functions (broad functions) specialized such as “nitrogen metabolism” “sulfur decrease Their enhancement these metabolic processes correlates reduced community which is key observed systems. This advances our understanding microbial ecosystem highlighting importance keystone taxa for It enhances ability predict transitions. scientific basis management invasion.

Effect of straw biochar amendment on tobacco growth, soil properties, and rhizosphere bacterial communities

Scientific Reports, Journal Year: 2021, Volume and Issue: 11(1)

Published: Oct. 20, 2021

Abstract Biochar is an effective soil conditioner. However, we have limited understanding of biochar effects on the tobacco growth and bacterial communities in rhizosphere. The aim this study was to investigate different straw amendment (0, 2, 10, 50 g/kg dry soil) growth, properties, rhizosphere by pot trials. Most agronomic traits increased when application rate varied from 0 10 g/kg, but were inhibited application. Soil pH, SOC, available nutrients urease, invertase, acid phosphatase activities all with application, whereas catalase activity decreased or remained unchanged. OTUs community diversity indices differed doses non-rhizosphere soils. And significant differences found between soils despite addition. Firmicutes , Proteobacteria Acidobacteria Bacteroidetes Actinobacteria dominant phyla samples, they had abundances treatment influenced effect. high dose (50 g/kg) similarity structure compared those soil. These results provide a better microecological benefits ecosystem.

Microbes with high–abundance attributes dominate the prokaryote communities of saline–alkali soil and construct more complex networks in the plant rhizosphere

Geoderma, Journal Year: 2023, Volume and Issue: 439, P. 116684 - 116684

Published: Oct. 11, 2023

Understanding the interactions between plants and microbes in terms of core and/or keystone taxa is great importance for promoting salt tolerant comprehensive utilisation saline–alkali lands. However, our knowledge about dominant microbial categories their response to plant growth limited. Here, we distinguished by classifying prokaryotic conducting network analysis Moreover, explored how these important varied rhizosphere bulk soils. Overall, six prokaryotes were identified. Approximately one–tenth species with high–abundance attributes accounted two–thirds total prokaryotes. showed that nearly all links among nodes positive; identified mainly belonged attributes. Furthermore, rhizosphere, a decreasing trend correlations diversity indices community compositions soil properties was observed compared those soil. more complex modules strongly correlated changes properties. These results suggest can recruit establishing syntrophic association taxa, which subsequently construct structure. Although ecological functions targeted need be confirmed, findings provide potential method constructing artificial microbiome multiple approaches, further helping develop strategies ameliorate stress
