Upon infection with A. brassicicola or treatment with methyl jasmonate MeJA, agb1 mutants show a significant delay in the induction of the MeJA-induced PR genes PDF1.2, OPR3 and PAD3 [18], whereas expression of the salicylic-acid-dependent PR1 was increased after infection with P. cucumerina [16]. Here, PADI3 is linked to infection.
