FIGURE LEGEND In the original article, there was a mistake in the legend for Figure 6 and Figure 7 as published. The numbering for Figure 6 was mixed with Figure 7 and not in agreement with the text: this mistake was introduced during proof stage, since the editing changed both legend and figure number. In addition, DC3000 should not be in italics. The correct numbering of Figures 6 and 7 appear below. FIGURE 6 | BCAA levels after exogenous application of 2-HAs to A. thaliana plants FIGURE 7 | ILA and LA abundance in response to P. syringae virulent strain infection. ERROR IN FIGURE In the original article, there was a mistake in Figures 2–4, and 6 as published. Due to the incorrect calculation of 2-HA level (a factor 50 was missed), all figures showing such measurements have to be replaced with the corrected y axis and limit of detection. The corrected Figures 2–4, and 7 appear below. (Figure presented.).
