In addition, upon pathogen infection we found stronger expression of the JA-responsive gene PDF1.2 (PLANT DEFENSIN1.2; Penninckx et al.,1998) (Fig. 2A) and the SA-responsive marker gene PR1 (PATHOGENESIS-RELATED PROTEIN 1; Uknes et al., 1992) (Fig. 2B) in Col-0 plants previously treated with fungal VCs compared with untreated (control) plants. The gene discussed is TMEM37; the disease is infection.
