Fusarium
head 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.
