Abstract
A novel antifungal peptide, LAMP-1a, was isolated from sand-elymus (Leymus arenarius) seeds. Expression of a synthetic gene encoding this peptide in Escherichia coli cells was obtained. The target peptide was expressed as a fusion with thioredoxin. Identity of the recombinant peptide to native LAMP-1a was confirmed by chromatography, mass spectrometry, and amino acid sequencing. LAMP-1a displayed a high inhibitory activity in respect of a number of phytopathogenic fungi in in vitro assays, which opens up possibilities for the gene encoding it to be used for genetic transformation of plants and for engineering pathogen-resistant crops
