Understanding the responses of biological communities to elevated CO2 (eCO2) is a central issue in ecology, but little is known about the influence of eCO2 on the structure and functioning (and consequent feedbacks to plant productivity) of the belowground microbial community. Here, using metagenomic technologies, we showed that 10 years of field exposure of a grassland ecosystem to eCO2 dramatically altered the structure and functional potential of soil microbial communities.

Elevated CO2 shifts the functional structure and metabolic potentials of soil microbial communities in a C4 agroecosystem
TLDR
It is implied that eCO2 has profound effects on the functional structure and metabolic potential/activity of soil microbial communities associated with C4 plants, possibly leading to changes in ecosystem functioning and feedbacks to global change in C4 agroecosystems.
The phylogenetic composition and structure of soil microbial communities shifts in response to elevated carbon dioxide
TLDR
In this study, phylogenetic microarrays were used to comprehensively survey the richness, composition and structure of soil microbial communities in a grassland experiment subjected to two CO2 conditions, and statistical analyses showed that the overall taxonomic structure of soils microbial communities was altered at eCO2.

TLDR
A positive feedback of eCO2 is revealed in forest soil microbial communities, which may provide new insight for a further understanding of forest ecosystem responses to global CO2 increases.
Metagenomic reconstruction of nitrogen cycling pathways in a CO2-enriched grassland ecosystem
Fungal Communities Respond to Long-Term CO2 Elevation by Community Reassembly
TLDR
Novel insights are provided into how eCO2 shapes soil fungal communities in grassland ecosystems and changes in the co-occurrence network topology were significantly associated with altered soil and plant properties under e CO2, especially with increased plant biomass and NH4 + availability.
Distinct responses of soil microbial communities to elevated CO2 and O3 in a soybean agro-ecosystem
TLDR
Overall, the analysis suggests possible mechanisms of microbial responses to global atmospheric change factors through the stimulation of C and N cycling by eCO2, the inhibition of N functional processes by eO3 and the interaction by e CO2 and e O3.
Elevated CO2 and nitrogen addition affect the microbial abundance but not the community structure in salt marsh ecosystem
Elevated CO2 and Warming Altered Grassland Microbial Communities in Soil Top-Layers
TLDR
The possible feedback of soil microbial communities to multiple climate change factors by the suppression of N cycling under warming, and enhancement of C and N cycling processes under either eCO2 alone or in interaction with warming is revealed.
Elevated CO2 influences microbial carbon and nitrogen cycling
TLDR
The findings suggest that the soil microbial community structure and their ecosystem functioning for C and N cycling were altered dramatically at eCO2, which provides new insights into the understanding of the feedback response of soil microbial communities to elevated CO2 and global change.

Elevated atmospheric CO2 affects soil microbial diversity associated with trembling aspen.
TLDR
Changes in soil biota are evidence for altered interactions between trembling aspen and the microorganisms in its surrounding soil, and support the theory that greater plant detritus production under elevated CO(2) significantly alters soil microbial community composition.
Assessment of 10 years of CO2 fumigation on soil microbial communities and function in a sweetgum plantation
Influence of plant diversity and elevated atmospheric carbon dioxide levels on belowground bacterial diversity
TLDR
Examination of soil samples taken from a biodiversity × CO2 grassland experiment showed that increased levels of carbon dioxide had no significant influence on both soil bacterial community composition and on bacterial richness, whereas plant diversity is responsible for qualitative changes (bacterial diversity).
Effects of Elevated Atmospheric CO2 on Soil Microbial Biomass, Activity, and Diversity in a Chaparral Ecosystem
TLDR
Bacterial diversity, described by 16S rRNA clone libraries, was unaffected by the CO2 treatment, but fungal biomass was stimulated, indicating that fungi were responsible for the stimulation of enzymatic activity in the FACE treatment.
Plant species richness, elevated CO2, and atmospheric nitrogen deposition alter soil microbial community composition and function
TLDR
The results demonstrate that plant species richness can directly regulate microbial activity and community composition, and that plantspecies richness is a significant determinant of microbial response to elevated CO2 and N deposition.
Fungal community composition and metabolism under elevated CO2 and O3
TLDR
It is concluded that fungal metabolism is altered under elevated CO2 and O3, and that there was a concomitant change in fungal community composition under elevated O3.
Plant species richness , elevated CO 2 , and atmospheric nitrogen deposition alter soil microbial community composition and function
We determined soil microbial community composition and function in a field experiment in which plant communities of increasing species richness were exposed to factorial elevated CO2 and nitrogen (N)…
How elevated pCO2 modifies total and metabolically active bacterial communities in the rhizosphere of two perennial grasses grown under field conditions.
TLDR
The data suggest that Actinobacteria in soil and Myxococcales (Deltaproteobacteria) in root are stimulated under elevated pCO2, which influenced mainly the active and root-associated component of the bacterial community.
Ammonia-oxidizing bacteria respond to multifactorial global change.
TLDR
This work examined the response of ammonia-oxidizing bacteria (AOB), microorganisms that mediate the transformation of ammonia into nitrite, to simultaneous increases in atmospheric CO2, precipitation, temperature, and nitrogen deposition, manipulated on the ecosystem level in a California grassland.
Elevated CO2 stimulates net accumulations of carbon and nitrogen in land ecosystems: a meta-analysis.
TLDR
The net N accumulation in plant and soil pools at least helps prevent complete down-regulation of, and likely supports, long-term CO2 stimulation of C sequestration, according to compiled data from 104 published papers that study C and N dynamics at ambient and elevated CO2.
