Barbera (disease susceptible) and the interspecific variety Castor (disease resistant) were infected at veraison by the ochratoxin A-producing fungus Aspergillus carbonarius in order to test the stilbene-synthase gene expression by reverse transcriptase-polymerase chain reaction. Stilbene (trans-resveratrol and piceatannol) synthesis was also analyzed. Stilbene-synthase gene expression was induced by the fungus and stilbenes were produced in both varieties, but was significantly higher in Castor. Castor displayed few disease symptoms while Barbera was highly infected. ER -
