Restriction Fragment Length Polymorphisms of Grapevine DNA with Phenylalanine Ammonia-Lyase cDNA

Total DNA was extracted from leaves of grapevines, 8 cultrvars of Vitis vinifera, Concord (V. labrusca) and a rootstock variety, F-3309. All the tested DNA showed different Southern analysis patterns using L-phenylalanine ammonia-lyase (PAL) cDNA of carrot (Daucus carota) as a probe. A dendrogram based on the RFLPs of PAL cDNA relatively agreed well with morphological taxonomy.
