In early Greek tragedy, the single character who dialogued with the chorus was called the protagonist. Aeschylus added a second character (the deuteragonist or antagonist) and Sophocles a third (the tritagonist). In modern theater, only the first term has been preserved, with the broad meaning of main character in any literary work.
From a literary perspective, an analogy can be drawn between a novel and biological interactions. A pathogen infecting plants acts as the protagonist, determining the plant's development. In this context, we can refer to the entry of an antagonist whose role is to control the pathogen's action without causing significant impact on the plant.
However, we have yet to mention the role of a third party: the tritagonist. Next-generation biostimulants can act precisely as this third actor, modulating the plant-pathogen-microbiome relationship in a way that neither the pathogen nor the defense mechanisms alone could achieve.
