Abstract

A non-specific lipid-transfer peptide (nsLTP) with fungicidal activity was isolated from Daucus carota sativa carrot seeds. Peptides were purified by a method including aqueous extraction, anion-exchange chromatography over CM-TSK-650M, and HPLC over a column of 250/8/4 Protein@Peptide C 18 using an acetonitrile gradient. The molecular weight of the peptide was determined as 9624 Da by mass spectrometry. The peptide was found to have fungicidal activity against the pathogenic fungus Verticillium dahliae. The partial N-terminal sequence, which was highly homologous to the N-terminal sequences of lipid-transfer peptides from seeds of rice, tobacco, and maize, was determined using Edman automated sequencing.
