Abstract
A 5 kDa peptide was purified from the basic protein fraction of radish (Raphanus sativus L.) storage organs. The amino-terminal amino acid s equence of this peptide (43 residues) shows homology with the subclass of thionins containing six cysteine residues of which crambin is a re presentative. The six-cysteine type thionin from radish displays in vi tro antifungal activity against Fusarium culmorum. This activity is ho wever substantially lower than that of the eight-cysteine type thionin s from cereals.
