APUM5 was induced in response to Pst DC3000 and A. brassicicola infection but did not affect susceptibility. (A) APUM5 gene expression pattern upon Pst DC3000 inoculation. AtPR1 was used as a positive control for Pst DC3000 inoculation. Error bars indicate standard deviations (n = 3). (Student’s t-test; *P < 0.01, ***P < 0.0001). (B) APUM5 was induced by A. brassicicola infection. PDF1.2 was used as a positive control for fungal pathogen infection. Error bars indicate standard deviations (n = 3). (Student’s t-test; **P < 0.001, ***P < 0.0001). (C) Bacterial growth analysis in APUM5 transgenic plants. NahG plant was used as a positive control for Pst DC3000 inoculation. Error bars indicate standard deviations (n = 3). (D) Quantitative analysis of necrotic lesion size upon A. brassicicola infection at 5 dpi.
