Accordingly, induction of JMT, a MYC2 target gene encoding an S-adenosyl-L-methionine:JA carboxyl methyltransferase that catalyzes formation of MEJA from JA, was severely reduced in med16 and med25 due to a combination of elevated levels before, and deficient induction after infection (Fig. 6D). The gene discussed is MED16; the disease is infection.
