In this work, we isolated major secondary\nmetabolites produced by three Trichoderma harzianum (T22, T39 and A6) and one T. atroviride (P1) isolates. Seven compounds obtained from fungal culture filtrates were extracted and characterised: two new molecules [T22 azaphilone and T39 butenolide] and five already known secondary metabolites [1-hydroxy-3-methyl-anthraquinone,1,8-dihydroxy-3-methyl-anthraquinone,harzianolide,6-n-pentyl-6H-pyran-2-oneand harzianopyridone].\nDifferent levels of antibiotic activity against various pathogens were detected. Since these compounds may be produced also during plant colonization, their ISR-inducing ability was evaluated. We obtained a reduction of disease symptoms on tomato and canola seedlings inoculated with Botrytis cinerea and Leptosphaeria maculans, respectively and treated with the fungal metabolites applied on the cotyledons at a concentration ranging from 1 to 10 ppm. RT-PCR analysis (chitinase IV, PR1 from Brassica napus and an endochitinase from Lycopersicum esculentum) indicated that treatments with the purified fungal compounds induced over-expression of the tested PR proteins in planta, thus indicating a role of Trichoderma secondary metabolites in the activation of plant defence genes. Moreover, a possible involvement of these fungal compounds in canola and wheat growth promotion was evaluated. Purified harzianolide and T39 butenolide induced a significant increase development of seedlings when applied directly on the roots."^^xsd:string ; pubblicazioni:affiliazioni "-Lorito M., Dip.
