Abstract: The defense potential of a tolerant American Yitis rupestris cultivar (Rupestris du Lot) and a susceptible European Vitis vinifera cultivar (Chardonnay) in response to UV-C irradiation was investigated, The expression of eight defense-related genes coding for enzymes of the phenylpropanoid pathway (phenylalanine ammonia Jyase and stilbene synthase), the octadecanoid pathway (lipoxygenase), and pathogenesis-related proteins (class I and Ill chitinases, B-I ,3-glllcanase, cIass 6 pathogenesis-related protein, and class 10 pathogenesis-related protein) was followed by real-time reverse transcription polymerase chain reaction (RT-PCR). Phenolic compound accumulation was monitored by microscopic observation. Accumulation of resveratrol, a major grapevine phytoalexin, was evaluated by HPLC, and chitinase and fi-I ,3- glucanase enzyme activities were measured. Both grapevine species responded to UV-C treatment by enhancement of defense mechanisms. Intensity of some defense responses was correlated with tolerance to diseases, as previously described for stilbene accumulation: the tolerant species responded more intensely to UV-C exposure than the susceptibJe one. UV-C irradiation is a practical and reproducible method for inducing grapevine defense responses and can be useful in determining the defense potentiaJ of grapevine cultivars. Keys words: grapevine, UV-C (200 to 280 nm), defense mechanisms, real-time RT-PCR Abbreviations: class I chitinase (Chitlb); class III chitinase (CH3); Iipoxygenase (LOX); phenylalanine ammonia lyase (PAL); class 6 pathogenesis-related protein (PR-6); class 10 pathogenesis-reJated protein (PR-IO); stilbene synthase (StSy) MenosAbstract: The defense potential of a tolerant American Yitis rupestris cultivar (Rupestris du Lot) and a susceptible European Vitis vinifera cultivar (Chardonnay) in response to UV-C irradiation was investigated, The expression of eight defense-related genes coding for enzymes of the phenylpropanoid pathway (phenylalanine ammonia Jyase and stilbene synthase), the octadecanoid pathway (lipoxygenase), and pathogenesis-related proteins (class I and Ill chitinases, B-I ,3-glllcanase, cIass 6 pathogenesis-related protein, and class 10 pathogenesis-related protein) was followed by real-time reverse transcription polymerase chain reaction (RT-PCR).
