Divergent Responses of the Diazotrophic Microbiome to Elevated CO₂ in Two Rice Cultivars.

ABSTRACT: The species-specific responses of plant growth to elevated atmospheric CO₂ concentration (eCO₂) could lead to N limitation and potentially influence the sustainability of ecosystem. Questions remain unanswered with regards to the response of soil N₂-fixing community to eCO₂ when developing high-yielding agroecosystem to dampen the future rate of increase in CO₂ levels and associated climate warming. This study demonstrates the divergent eCO₂ influences on the paddy diazotrophic community between weak- and strong-responsive rice cultivars. In response to eCO₂, the diazotrophic abundance increased more for the strong-responsive cultivar treatments than for the weak-responsive ones. Only the strong-responsive cultiva
