Gamma-thionins (also known as plant defensins) are small evolutionarily related proteins of plants that serve to defend them against parasites. The following plant proteins belong to this family: Gamma-thionins from Triticum aestivum (Wheat) endosperm (gamma-purothionins) and gamma-hordothionins from Hordeum vulgare(Barley) are toxic to animal cells and inhibit protein synthesis in cell free systems. A flower-specific thionin (FST) from Nicotiana tabacum (Common Tobacco).
