Ectopic expression of MdMYB30 in Arabidopsis increases resistance to Pst DC3000. a Phenotypes of WT, MdMYB30 OE4, OE5, and OE6 infected with Pst DC3000 for 0, 3, 5, 7, and 13 days (scale bars: 1 cm). b Callose deposition of WT and MdMYB30 ectopic expression Arabidopsis infected with Pst DC3000 for 5 days (scale bars: 500 μm). c 3′,3′-Diaminobenzidine (DAB) staining for H₂O₂ in the leaves of WT and MdMYB30 ectopic expression Arabidopsis infected with Pst DC3000 for 5 days. d DAB staining areas and intensity were determined with ImageJ software. e Nitroblue tetrazolium (NBT) staining for superoxide in the leaves of the WT and MdMYB30 ectopic expression Arabidopsis infected with Pst DC3000 for 5 days. f NBT staining areas and intensity were determined with ImageJ software. Bars with different letters are significantly different at P < 0.05 according to Tukey’s single factor test. Data are mean ± standard deviation. At least three biological repetitions were performed
