Metagenomic analysis of Free-air CO2 enrichment (FACE) area
Microorganisms have a remarkable ability to mitigate elevated CO2 levels through carbon concentrating mechanisms (CCM). Free-air CO2 enrichment (FACE) experiments provide insight into plant behavior under heightened CO2 conditions in natural settings. Consequently, microorganisms in FACE regions experience sustained exposure to elevated CO2 concentrations. This study employs meta-genomic techniques to explore microbial communities in a distinct FACE area thriving in high CO2 environments. The bacterial community, archaea, taxonomic composition and functional potential are investigated using next-generation sequencing
