Tentoxin
Encyclopedia
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
.
Tentoxin was first isolated from Alternaria alternata (syn. tenuis) and characterized by George Templeton et al. in 1967.
Tentoxin has also been used in recent research to eliminate the polyphenol oxidase
(PPO) activity from seedlings of higher plants.
Tetrapeptide
A tetrapeptide is a peptide consisting of four amino acids joined by peptide bonds. Many tetrapeptides are pharmacologically active, often showing affinity and specificity for a variety of receptors in protein-protein signaling...

Herbicide
Herbicides, also commonly known as weedkillers, are pesticides used to kill unwanted plants. Selective herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic "imitations" of plant...
