Unveiling essential host genes and keystone microorganisms of the olive tree holobiont linked to Verticillium wilt tolerance

Keystone microbial taxa, particularly Actinophytocola and Nocardia, are proposed to play an important role against V. dahliae within the indigenous olive root microbiota under natural conditions. Moreover, our findings underscore the importance of studying keystone taxa along with essential host plant genes to holistically understand plant-microbiota interactions and explore their potential in disease management. This integrative approach provides insights into the complex dialogue taking place between the host plant and its microbiota, offering potential targets for microbiome engineering to enhance olive resilience against VWO.
