赤霉病是小麦、大麦、玉米等粮食作物的主要真菌病害之一。FHB物种复合体产生真菌毒素，导致质量和产量降低，以及人类和动物健康风险。抗性育种结合化学和/或栽培防治措施具有可持续控制FHB的潜力。然而，由于常规育种的遗传增益有限，因此FHB抗性育种进展缓慢，需要互补的基因组工具来探索和操纵遗传资源。小麦赤霉病抗性育种也受到性状的数量性质、对赤霉病发病机理的有限理解和宿主基因组的大尺寸的阻碍。本文重点介绍了对FHB的严重程度，发病机制和遗传控制策略的知识状态。现有的基因组技术用于解开潜在的机制，在占主导地位的FHB物种，禾谷镰刀菌的毒力，进一步概述。跨学科合作是成功开发和部署抗赤霉病基因型小麦种植者所必需的。(C)2016爱思唯尔有限公司版权所有
Fusarium head blight (FHB) is one of the main fungal diseases of grain crops such as wheat, barley and maize. The FHB species complex produces mycotoxins that cause quality and yield reductions, as well as human and animal health risks. Resistance breeding, integrated with chemical and or cultural control practices has the potential for sustainable control of FHB. However, breeding for FHB resistance has been slow due to limited genetic gains from conventional breeding, requiring complementary genomic tools to explore and manipulate genetic resources. Breeding for FHB resistance in wheat is also hampered by the quantitative nature of the trait, limited understanding of FHB pathogenesis and the large size of the host genome. This paper highlights the state of knowledge on FHB severity, pathogenesis and genetic control strategies. Available genomic technologies used to uncoil the underlying mechanisms of virulence in the dominant FHB species, E graminearum, are further outlined. Interdisciplinary collaboration is required for successful development and deployment of FHB resistant genotypes to wheat growers. (C) 2016 Elsevier Ltd. All rights reserved.
