A prevalent concept for colonization and evolution among plant pathogens their hosts stems from a post-Darwinian paradigm rooted in the formalized assumption of “specialized parasitism.” Seminal studies on rust fungi socioeconomic importance integrated such an evolutionary perspective driven by strict coevolution hosts. Following this fundamentally unfalsifiable assumption, theories regarding host-switching parasites were dismissed. If occurred, process would depend upon origin specific novel mutations that allow infections previously unexploited or host groups, acquisition broader range. After mutation arose, be locked into eventual dead end (e.g., codified under Dietel’s Law). Accordingly, if are highly specialized (one parasite, one plant), then new associations rare otherwise unpredictable. Similar schools thought became dominant animal established during same period (i.e., Müller’s rule, Fuhrmann’s Fahrenholz’s rule). Other focused took host–one parasite idea granted only tentatively included insights subsequent development pathogen scientific frameworks. Later, emerging neo-Darwinian views, cospeciation was conflated with gene-for-gene rule postulated 1956 which has persisted phytopathologists even to present day. In parallel history, conceptual pathologists parasitologists assumed is cannot predicted, given dependence elusive special mutation. contrast, current impacts increasing frequency epidemics across globe, influence health food security, suggest historical approach fails describing complex biosphere dynamic change. The Stockholm (SP) provides powerful alternative what may regarded as standard model coevolutionary diversification. SP creates theoretical workbench emergence can evaluated predicted. exploring dynamics phytoplasmas, emergent group substantial risk security. New examined, pushing resolution internal conflicts generated assumptions model, dominated reasoning more than century pathology research.
