TMEM37 and infection: To evaluate the contribution of the SA and JA signalling pathways to the increased resistance of srfr1‐1 to H. schachtii, transcript levels of SA‐responsive (EDS1, PAD4 and PR1) and JA‐responsive (MYC2 and JAZ1) genes were determined in 14‐day‐old Arabidopsis seedlings at 3 days post‐infection and compared with transcript levels in mock‐treated seedlings.
