For many years pathogens of wheat have remained poorly understood. Hindered by an inaccessible host and the obligate nature of many of the pathogens, our understanding of these interactions has been limited compared to other more amenable pathosystems. However, breakthroughs over recent years have shed new light on diseases of wheat, particularly those caused by the genetically tractable necrotrophic pathogens. We now understand that many of the necrotrophic fungal pathogens do interact with wheat in a strict gene-for-gene relationship, and that pathogen and host partners in these interactions have now been identified. This improved understanding of necrotrophic effector biology has fundamentally changed the way we consider these important wheat diseases.
多年来，小麦病原体的研究一直很不充分。由于宿主难以接近以及许多病原体的专性特性，与其他更容易研究的病理系统相比，我们对这些相互作用的了解受到了限制。然而，近年来的突破为小麦疾病，特别是由遗传上易于处理的坏死型病原体引起的疾病，带来了新的认识。我们现在知道，许多坏死型真菌病原体与小麦的相互作用是严格的基因对基因关系，并且这些相互作用中的病原体和宿主伙伴已经被确定。对坏死型效应物生物学的这种更深入的理解，从根本上改变了我们对这些重要小麦疾病的看法。
