چکیده	Didymella glomerata and Truncatella angustata associated with grapevine trunk diseases (GTDs) in Iran, were grown in vitro to evaluate the production of phytotoxic metabolites as potential pathogenicity determinants. 2,5-Dihydroxymethylfuran and (þ)-6- hydroxyramulosin were isolated from the culture filtrates of D. glomerata and T. angustata, respectively. They were identified by physical and spectroscopic (essentially 1 D and 2 D 1 H and 13C NMR and ESIMS) methods and X ray analysis. Both compounds induced significant necrosis and curling on the leaves of the host plant Vitis vinifera L. and the effects were concentration dependent. No effect was observed on the leaves of the non-host Solanum lycopersicum L.. plant
