Fusarium ear blight (FEB) is a devastating fungal disease of cereal crops. Outbreaks are sporadic and current control strategies are severely limited. This review highlights the use of Arabidopsis to study plant-FEB interactions. Use of this pathosystem has identified natural variation in Fusarium susceptibility in Arabidopsis, and native plant genes and signalling processes modulating the interaction. Recent breakthroughs include the identification of plant- and insect-derived small molecules which increase disease resistance, and the use of a host-induced gene silencing (HIGS) construct to silence an important Fusarium gene to prevent infection. Arabidopsis has also been used to study other fungi that cause cereal diseases. These findings offer the potential for translational research in cereals which could yield much-needed novel control strategies.
镰刀菌穗腐病（FEB）是一种毁灭性的谷类作物真菌病。疫情零星发生，目前的控制策略受到严重限制。本综述重点介绍了利用拟南芥研究植物与 FEB 相互作用。利用该病理系统已经确定了拟南芥中对镰刀菌易感性的自然变异，以及调节相互作用的本地植物基因和信号转导过程。最近的突破包括鉴定出植物和昆虫衍生的小分子，这些小分子可以提高抗病性，以及利用宿主诱导基因沉默（HIGS）构建体来沉默一个重要的镰刀菌基因以防止感染。拟南芥也被用于研究其他引起谷类疾病的真菌。这些发现为谷类作物的转化研究提供了潜力，可能会产生急需的新型控制策略。
