Linking microbiome structure to functional analysis identifies resilient Pseudarthrobacter, Pseudomonas, and Streptomyces antagonists of Phytophthora infestans in tomato
Ada Linkies
IntroductionLate blight, caused by Phytophthora infestans, remains one of the most destructive tomato diseases, driving the need for sustainable measures to reduce intensive fungicide use. Plant-associated microbial communities offer a promising but still underexplored source of biological control agents. Moreover, links between community-level microbiome patterns and functionally effective antagonists remain poorly resolved.MethodsIn this study, we combine culture-dependent isolation, functiona
