ResumenA study was carried out to determine the changes in phenolic composition induced by tuberculosis infection in olive trees. Four ethanolic extracts were compared: olive leaf from shoots affected by Pseudomonas savastanoi pv. Savastanoi, nodules induced by this bacteria, leaf from healthy (asymptomatic) shoots, and shoots. Among the differences found, the presence of a phenolic compound in nodules was significant in much larger quantities than in leaf or shoots. Mass spectrometric analysis showed this compound to be verbascoside. The enhancement of its biosynthesis could be related to the defense mechanisms of the tree in the nodules induced by P. savastanoi and suggests the possibility of exploration of natural and biotechnological sources of this compound.
