Overexpression of BEC1019 in Zhoumai 26 wheat increased susceptibility to the necrotrophic pathogen Gaeumannomyces graminis var. tritici (Ggt), whereas silencing BEC1019 decreased susceptibility to Ggt. (A) Macroscopic responses to Ggt infection on the stems and roots of BEC1019-overexpressing and RNAi lines and wild-type control plants. (B) Relative Ggt biomass of control wheat and BEC1019 overexpressing and RNAi plants. (C) Microscopic analysis showing the growth of Ggt hyphae on the stems of wild-type plants and BEC1019-overexpressing and RNAi plants after inoculation. Scale bar = 25 µm. (D) Transcript levels of BEC1019 in Ggt-infected base stems and roots of overexpressing and RNAi transgenic plants. Double asterisks indicate significant differences relative to the control plants (p ≤ 0.01, according to t-tests).
