Effects of Intact Soil Bacterial Community on Plant Growth and Soil Physicochemical Properties

The Fifth International Conference on Biological Information and Biomedical Engineering, 2021
Soil microorganisms play an important role in the nutrient transformation and circulation of terrestrial ecosystem. Some studies found that intact soil microbial community could purify the soil environment and promote plant growth. However, the effects of intact soil microbial community and their affect mechanisms were not clearly known.

Biogeographical patterns of soil bacterial communities

Environmental Microbiology Reports, 2009
Summary This study provides the first maps of variations in bacterial community structure on a broad scale based on genotyping of DNA extracts from 593 soils from four different regions of France (North, Brittany, South‐East and Landes).

Shifts in the soil bacterial community along a salinity gradient in the Yellow River Delta

Land Degradation and Development, 2020
Soil salinization has rapidly encroached from the coastline to inland areas over the past two decades in the Yellow River Delta (YRD). Soil samples were collected from low‐ (LSW), medium‐ (MSW), and high‐ (HSW) salinity wetlands at a depth of 0–20 cm for

The Biogeography of Ammonia-Oxidizing Bacterial Communities in Soil

Microbial Ecology, 2009
Although ammonia-oxidizing bacteria (AOB) are likely to play a key role in the soil nitrogen cycle, we have only a limited understanding of how the diversity and composition of soil AOB communities change across ecosystem types. We examined 23 soils collected from across North America and used sequence-based analyses to compare the AOB communities in ...

Effects of a sulfonylurea herbicide on the soil bacterial community

Environmental Science and Pollution Research, 2014
Sulfonylurea herbicides are widely used on a wide range of crops to control weeds. Chevalier® OnePass herbicide is a sulfonylurea herbicide intensively used on cereal crops in Algeria. No information is yet available about the biodegradation of this herbicide or about its effect on the bacterial community of the soil.

Ameliorative effects of silicon fertilizer on soil bacterial community and pakchoi (Brassica chinensis L.) grown on soil contaminated with multiple heavy metals.

Environmental Pollution, 2020
Contamination of soil with heavy metals seriously harms the growth of crops. Silicon fertilizer is known to promote growth of crops and alleviate heavy metals stresses in vegetables.

Exposure to fungicide difenoconazole reduces the soil bacterial community diversity and the co-occurrence network complexity.

Journal of Hazardous Materials, 2020
Difenoconazole is a triazole fungicide that is widely used worldwide and has been frequently detected in agricultural soils, but its ecotoxicological effect on soil bacterial community remains unknown.

Influence of the neonicotinoid insecticide thiamethoxam on soil bacterial community composition and metabolic function.

Journal of Hazardous Materials, 2020
Understanding of neonicotinoid insecticides toxicity on non-target organisms, such as bees, has indirectly promoted their soil treatment use. However, their effect on soil ecosystems haven't fully understood.

Transcriptional activity of paddy soil bacterial communities

Environmental Microbiology, 2009
Summary Bulk mRNA was used to explore the transcriptional activity of bacterial communities in oxic versus anoxic paddy soil. Two microbial cDNA libraries were constructed from composite samples using semi‐randomly primed RT‐PCR. cDNAs averaged 500–600 bp in length and were treated as expressed sequence tags (ESTs)

Towards a Natural History of Soil Bacterial Communities

Trends in Microbiology, 2018
Despite the enormous diversity of bacteria, a recent study reveals that soils are globally dominated by a small list of taxa. Characterizing the traits of these bacteria offers the potential for predicting functional differences among soil communities.
