Overexpression of MebZIP3 and MebZIP5 confers improved disease resistance against cassava bacterial blight. (A,B) The bacterial number of Xam in WT, MebZIP3 (A) and MebZIP5 (B) transgenic plant leaves at 0, 2, 4, and 6 dpi of 10⁸ cfu ml^-1 of Xam. (C) The pictures showing the plant leaves at 0 and 6 dpi of Xam. Bars = 1 cm. (D) Quantification of H₂O₂ in plant leaves. (E) The callose depositions in plant leaves. White dots in the figures indicated callose depositions in plant leaves, and the average data was shown. At least 15 cassava leaves were assayed for every biological repeat, and at least three biological repeats were performed. Asterisk symbols (^∗) indicting the significant differences in comparison to WT at p < 0.05.
