The expression of defense genes responsive to SA (PR1 and PR2), JA/ET (PR3c, lipoxygenase 9 (LOX9), 1-aminocyclopropane carboxylic acid oxidase (ACO), ET-response factor (ERF1)), and ABA (NCED2) was evaluated by RT-qPCR in treated leaves before and after pathogen infection (Figure 2). Here, TMEM37 is linked to infection.
