Tentoxin

Tentoxin is a natural cyclic tetrapeptide produced by phytopathogenic fungi from genus Alternaria (A. tenuis and A. alternata). It selectively induces chlorosis in several germinating seedling plants. Therefore, tentoxin may be used as a potential natural herbicide.

Tentoxin was first isolated and characterized by George Templeton et al. in 1967 from Alternaria tenuis.
