Constitutive Metabolite Profiling of European and Asian Fraxinus with Varying Susceptibility to Ash Dieback.

ABSTRACT: Hymenoscyphus fraxineus is an invasive pathogen native to East Asia, responsible for the widespread mortality of European ash (Fraxinus excelsior) throughout Europe. Asian ash species, which co-evolved with H. fraxineus, are considered more tolerant than European ash. However, within European ash populations, a small proportion of genotypes show low susceptibility to the pathogen. This study sought to characterize the underlying defence mechanisms to H. fraxineus by performing untargeted constitutive metabolomics profiling of phloem and leaf tissue of from thirteen F. excelsior genotypes (nine tolerant and four susceptible) and five genotypes representing three Asian ash species (F. mandshurica, F. platypoda, and F. chinensis). Here we report 57 and 36 compounds associated with lower or hi
