Plants that are phytosedentary have built up over the millennia a resistome capable of perpetuating their life in the globosphere. This resistome, whether transmissible or not, defines lasting resilience. The knowledge of the passive or active action of the vertical or horizontal aspect of the resistance, will allow to better explain the origin of the defense mechanism apart from the general view of the R gene and to understand in a transmissibility the new nature of the neo-resistance put in place, either by adaptation or by heritability.
