Coronatine is a plant growth regulator produced by Pseudomonas syringae. Coronatine simulates bioactive jasmonic acid (HY-122464A) conjugates or octadecanoid signal molecules of higher plants to make plants appear pathogenic symptoms. Coronatine promotes the virulence of Pseudomonas syringae in plants by activating the signal cascade that inhibits the accumulation of Salicylic acid (HY-B0167)[1][2][3][4].
