Unraveling the CO2—Microbe Nexus: A Conceptual Framework for Nitrogen Fixation Efficiency in Legume—Rhizobium Systems
Elevated atmospheric CO2, a principal driver of anthropogenic climate change, imposes emerging constraints on symbiotic nitrogen fixation (SNF), particularly within legume—Rhizobium systems. This study critically assesses the impact of CO2 enrichment on nitrogen fixation efficiency (NFER) in Rhizobium spp., a microbial...
