Fusarium graminearum is a major pathogen of wheat causing head blight (FHB). Its ability to colonize via seedling root infection has been reported recently. Our previous study on rot (FRR) disclosed histological characteristics pathogenesis and defense that mirror processes spike infection. Therefore, it would be interesting understand whether genes relevant for FHB resistance are induced in roots. The concept similar-acting mechanisms provides basis research at broad crop plants. However, molecular responses involved FRR as well their relation unknown. To test the hypothesis conserved response, candidate gene expression was conducted activity selected prominent defense-related roots, adult plant spikes, shoots. examined stages assess age-related pattern disease resistance. This offers first evidence significant genetic overlap responses, both local distant tissues. results point development-specific rather than organ-specific determinants resistance, suggest roots an model studies wheat−Fusarium interactions.
