Penicillium rubens strain 212 (PO212) is an effective inducer of resistance mechanisms in tomato plants against Fusarium oxysporum f.sp. lycopersici . During the interaction of PO212 with the plant, different classes of molecules may act as elicitors such as certain secreted endo-xylanases. The aim of this work was to elucidate the possible role of the xylanolytic system of PO212 in its biocontrol activity. We identified poten...
