  abstract = {{T}he priming effect ({PE}) is a key mechanism contributing to the carbon balance of the soil ecosystem. {A}lmost 100 years of research since its discovery in 1926 have led to a rich body of scientific publications to identify the drivers and mechanisms involved. {A} few review articles have summarised the acquired knowledge; the last major one was published in 2010. {S}ince then, knowledge on the soil microbial communities involved in {PE} and in {PE} + {C} sequestration mechanisms has been considerably renewed. {T}his article reviews current knowledge on soil {PE} to state to what extent new insights may improve our ability to understand and predict the evolution of soil {C} stocks. {W}e propose a framework to unify the different concepts and terms that have emerged from the international scientific community on this topic, report recent discoveries and identify key research needs. {S}eventy per cent of the studies on the soil {PE} were published in the last 10 years, illustrating a renewed interest for {PE}, probably linked to the increased concern about the importance of soil carbon for climate change and food security issues. {A}mong all the drivers and mechanisms proposed along with the different studies to explain {PE}, some are named differently but actually refer to the same object. {T}his overall introduces 'artificial' complexity for the mechanistic understanding of {PE}, and we propose a common, shared terminology. {D}espite the remaining knowledge gaps, consistent progress has been achieved to decipher the abiotic mechanisms underlying {PE}, together with the role of enzymes and the identity of the microbial actors involved. {H}owever, including {PE} into mechanistic models of {SOM} dynamics remains challenging as long as the mechanisms are not fully understood. {I}n the meantime, empirical alternatives are available that reproduce observations accurately when calibration is robust. {B}ased on the current state of knowledge, we propose different scenarios depicting to what extent {PE} may impact ecosystem services under climate change conditions. {R}ead the free {P}lain {L}anguage {S}ummary for this article on the {J}ournal blog.},
