Resumen:
An antibiotic called fragarin showing activities against bacterial and fungal plant pathogens was isolated and purified by FPLC chromatography from the soluble fraction of strawberry leaves. The molecular weight value determined by mass spectrometry is 316 Da. Fragarin remains fully active after protease treatment or alkaline hydrolysis at 100ºC for 20 min. Biological and chemical analyses suggest that fragarin may be a new type of an antimicrobial preformed compound ? phytoanticipin - and would constitute a primary non-specific barrier of strawberry defense.
