Molecular dissection of Xinong 511 spike rachis response to Fusarium head blight infection.

ABSTRACT: Fusarium head blight (FHB, also known as wheat scab or ear blight), caused primarily by the Fusarium graminearum, is a worldwide disease of wheat (Triticum aestivum L.). Studying the pathogen expansion patterns and molecular mechanisms of disease resistance in resistant wheat varieties is crucial for advancing wheat disease management strategies. Here, we found a significant difference between two wheat cultivars with different resistances, and it was revealed that they exhibited divergent pathogen infestation process. The susceptible cultivar showed extensive pathogen in the spike rachis, while resistant varieties only had limited pathogen spread and colonization. Meanwhile, wheat resistance to FHB was positively correlated with transcriptional reprogramming in the early stages, with high
