  abstract = {{M}arine diazotrophs are microscopic planktonic organisms ubiquitous in the ocean, that play a major ecological role: they supply nitrogen to the surface ocean biosphere, an essential but scarce nutrient in similar to 60% of the global ocean. {O}ver the past decades, they have attracted considerable attention, with numerous studies providing key insights into their diversity, lifestyle, biogeographical distribution, and biogeochemical role in planktonic ecosystems. {A}n increasing number of studies show that these microbes regulate marine productivity and shape the food web by alleviating nitrogen limitation, thereby contributing to carbon sequestration to the deep ocean. {Y}et, the diazotroph-derived organic carbon exported to the deep ocean is still poorly quantified, limiting robust estimates of the ocean's contribution to {CO}2 sequestration and climate change mitigation under present and future conditions. {T}his knowledge gap reflects the complexity of diazotroph export pathways to the deep ocean, whose quantification and variability drivers remain difficult to resolve with current methods. {T}his review aims to synthesize current knowledge on the role of diazotrophs in their interactions with the food web and the biological carbon pump ({BCP}), reanalyze existing datasets, identify key knowledge gaps, and propose future research directions.},
