摘要:

小麦赤霉病是一种小麦穗部病害,严重影响小麦的产量和品质。挖掘小麦赤霉病抗性基因,揭示其抗病机制,对于提高小麦赤霉病抗性,推动小麦赤霉病抗性育种进程具有重要的意义。系统阐述了抗赤霉病相关QTL、多组学研究、细胞壁防卫、信号转导、次生代谢物合成、识别应答等小麦赤霉病抗性机制的研究进展,并对未来小麦赤霉病抗性机制的研究方向进行了探讨。希望以此加深研究者对小麦赤霉病抗性机制的了解,为未来小麦抗赤霉病分子机制研究提供理论基础,为小麦抗赤霉病遗传改良提供丰富的基因资源。

Abstract:

Fusariumhead blight (FHB) is a destructive disease of wheat that reduces yield and grain quality. The urging task of screening for resistance genes and understanding mechanisms underlying FHB resistance will certainly help to win the fight against FHB in the near future. This review expounded systematically the following main sections: QTL for FHB resistance, omics, cell wall fortification, signaling transduction, secondary metabolite synthesis, recognition and resistance mechanism study, and discussed the research direction of FHB resistance mechanism. The review was expected to provide theoretical reserves for further revealing the molecular mechanism on regulating wheat FHB resistance, and provide excellent gene resources for improving wheat FHB germplasm resources.

Key words: wheat, Fusasium head blight, resistance mechanism
