Fusarium graminearum causes Fusarium Head Blight (FHB), a devastating disease of cereal plants such as wheat and barley. Ethylene (ET) signaling was known as negative regulator of the disease resistance against F. graminearum in Arabidopsis, wheat and barley (Chen et al.,2009, New Phytologist, 182: 975–983). ERF71 and ERF73 are plant specific transcription factors, which is located at downstream of ET-signaling pathway. This study aims to investigate the involvement of ERF71/ERF73 in regulating disease resistance to F. graminearum. The erf71, erf73 and erf71erf73 double mutant showed enhanced disease resistance against F. graminearum compare to the wild-type. In contrast, susceptible phenotypes were observed in ERF71ox and ERF73ox plants. In addition, expression of ET-responsive genes such as PDF1.2a and PR3 genes were suppressed in erf71, erf73 and erf71erf73 plants. In contrast, expression of these genes are higher in the ERF71ox and ERF73ox compare to the wild-type. Thus, ERF71 and ERF73 genes are involved in the ET-signaling pathway regulating disease resistance to F. graminearum.
