[Abstract]  Fusarium graminearum, the major causal agent of Fusarium head blight (FHB), causes serious wheat yield losses and a threat to human and animal health. The main efforts to combat the disease are the research of pathogenesis mechanisms and breeding for disease resistance plants. The efficiency of these actions could be evaluated by reliable inoculation assay, which is performed by accurate and repeatable inoculation methods. Hence, a standard procedure of effective wheat inoculation should improve the accuracy of pathogenicity evaluation. Here, we present a protocol for wheat spike inoculation with fungal conidial suspensions or fungus agar discs. These methods show highly reproducibility and accuracy on wheat infection experiment in laboratory conditions. [摘要]  Fusarium graminearum 是镰刀菌枯萎病(FHB)的主要致病因子,会导致严重的小麦产量损失,并对人类和动物健康构成威胁。 抗击该病的主要工作是发病机制的研究和抗病植物的育种。 可以通过可靠的接种测定来评估这些作用的效率,所述可靠的接种测定通过准确且可重复的接种方法进行。 因此,有效小麦接种的标准程序应提高致病性评估的准确性。 在这里,我们提出了小麦穗接种与真菌分生孢子悬浮或真菌琼脂圆盘的协议。 这些方法在实验室条件下对小麦感染实验显示出高度的重现性和准确性。

【背景】禾谷镰刀菌是一种破坏性的真菌病原体,它会对谷类作物造成全球严重的镰刀菌枯萎病(FHB)病。近年来,随着全球气候变化和农业实践的变化,FHB的发病率增加。另外, F. graminearum 产生几种真菌毒素,包括单端孢菌毒素霉菌毒素脱氧雪腐镰刀菌烯醇(DON),它威胁人类和动物的健康(Tanaka et al。,1988; Windels,2000; Su et al。 ,2018)。迄今为止,控制FHB的最有效工具来源于抗病植物的致病机制和育种研究(Steiner et al。,2009; Son et al。,2013)。

由于缺乏通常在宿主中诱导基因对基因介导的抗性的病原体特化模式(van Eeuwijk et al。,1995), ...
