Sensitivity of Blumeria graminis and Rhynchosporium commune to Me‐JA treatment and inducibility of JA‐related genes. (a, b) Number of B. graminis (Bgh) colonies (a) and length of R. commune lesions (b) on barley leaf segments pretreated for 24 hr with 45 μm Me‐JA (black circles) or water (control, grey circles). (c–f) Relative transcript levels of HvLOX2 (c, d) and HvJIP60 (e, f) in uninoculated leaf segments (black bars) or leaf segments inoculated (patterned bars) with B. graminis (c, e) or R. commune (d, f). α‐TUB was used as reference gene. Experiments were performed on middle segments of the second leaves of plants grown for 14 days in control conditions. Means (±SE) from three replicate experiments (n = 3)
