Tentoxin is a natural cyclic tetrapeptide produced by phytopathogenic fungus Alternaria alternata. It selectively induces chlorosis in several germinating seedling plants. Therefore, tentoxin may be used as a potential natural herbicide, and is a lactam.[1]
Tentoxin was first isolated from Alternaria alternata (syn. tenuis) and characterized by George Templeton et al. in 1967.[2]
Tentoxin has also been used in recent research to eliminate the polyphenol oxidase (PPO) activity from seedlings of higher plants.[3]
