UPLC-ESI-TOF-MS Profiling of Metabolome Alterations in Barley (<i>Hordeum vulgare</i> L.) Leaves Induced by <i>Bipolaris sorokiniana</i>.

ABSTRACT: Spot blotch of barley (Hordeum vulgare L.), caused by Bipolaris sorokiniana, is responsible for major losses in crop yield. Breeding-resistant barley varieties have proven to be an effective countermeasure for protecting agricultural production. Plants react to pathogen attacks by up-regulating secondary metabolites. Marker compounds for a B. sorokiniana infection are examined by untargeted UPLC-TOF-MS metabolomics and lipidomics techniques. Through the analysis of nine quantitatively resistant and susceptible barley genotypes, derived from the nested association mapping population HEB-25, followed by structure identification experiments and spore germination assays, 57 metabolites are identified. In addition to previously known metabolites, the unknown compounds 5-car
