摘要

Fusarium graminearum Schwabe (teleomorph: Gibberella zeae) is a destructive fungus, causing economically important diseases such as seedling blight, root and crown rot and head blight on small grain cereals, in particular wheat and barley. It is a devastating phytopathogen, not only due to causing significant yield losses, but also because of contaminating plant tissues with trichothecenes and other types of mycotoxins, which are harmful for human animal health. Several disease management strategies are used to decrease yield losses and mycotoxin production in cereals caused by this pathogenic fungus. Among various disease control methods, use of resistant cultivars could be the most effective way to combat diseases caused by F. graminearum in cereals. However, any plant cultivar with complete resistance against this pathogen was not reported worldwide and only some of the host cultivars with partial resistance against F. graminearum were identified, so far. Therefore, understanding biochemical and cytomolecular aspects of interaction in F. graminearum-cereals pathosystems would be valuable for designing novel management strategies against various diseases caused by this hemibiotrophic fungal pathogen on economically important cereals. This review is focused on biology, pathogenicity, and genetic structure of F. graminearum populations together with the role of reactive oxygen species (ROS) and antioxidant systems in association with plant cell wall in defense responses of cereals, as the main resistance mechanisms against this destructive fungus.

Graminearum造成的疾病的最有效方法。然而，到目前为止，未在全球范围内报道任何具有完全抵抗该病原体的植物品种，并且只有一些具有部分抗性的宿主品种。因此，了解F. Graminearum-eyeals患者的生化和细胞分子方面对F. Graminearum-谷物的相互作用，对于在经济上重要的谷物上设计针对这种血统营养病病原体引起的各种疾病的新的管理策略是有价值的。本综述专注于F. Graminearum群体的生物学，致病性和遗传结构以及与谷物防御反应的植物细胞壁与谷物墙壁相关联的反应性氧（ROS）和抗氧化体系的作用，作为反应的主要抵抗机制破坏性真菌。
