Abstract Legume-Rhizobia symbiosis plays a crucial role in both agricultural and ecological contexts, providing a sustainable solution for improving soil fertility and mitigating climate change through carbon storage. This thorough examination delves into the complex mechanisms of this mutually beneficial relationship, investigating the molecular, physiological, and ecological aspects that govern the interaction between leguminous plants and nitrogen-fixing rhizobia bacteria. In this review, we analysed the key elements of this symbiosis, including the processes of nodulation, the pathways of communication, and the genetic factors that enable nitrogen fixation. Furthermore, we scrutinize the factors that influence the success of this partnership, which range from soil conditions and the diversity of host plants to the effectiveness of specific strains of rhizobia. Additionally, the broader implications of legume-rhizobia symbiosis on carbon storage were also reviewed. This mutualistic relationship not only enhances plant growth and productivity but also stimulates the release of substances from the roots that enrich the organic matter in the soil and contribute to long-term carbon retention. We assess the potential of this process to reduce greenhouse gas emissions and combat climate change, emphasizing its significance in sustainable agriculture and ecosystem management. Moreover, we also explore recent advancements in biotechnology and microbial engineering, which offer promising opportunities to optimize legume-rhizobia interactions for increased agricultural productivity and enhanced carbon storage. This comprehensive examination synthesizes the current state of knowledge on legume-rhizobia symbiosis and its role in carbon storage, shedding light on the multifaceted advantages of this ecological partnership for a sustainable and resilient future.
