title: Isolation of a 6.2 kb genomic fragment carrying the Adh1 gene of tomato and its expression in transgenic tobacco.
abstract: An 11 kb Eco RI genomic fragment containing the alcohol dehydrogenase (Adh1) gene was cloned. Cross-hybridization with three Adh2 cDNA clones suggested that the entire coding region of the Adh1 gene was contained on a 6.2 kb Xba I/Hind III subfragment. Using RFLP linkage analysis, the genomic clone was mapped on chromosome 4 between the markers TG 182 and TG 65 in a position corresponding to the Adh1 locus. To further confirm the Adh1 origin of the genomic clone, tobacco plants were transformed with the 6.2 kb Xba I/Hind III genomic subfragment. Isozyme analysis demonstrated that in transgenic tobacco plants functional tomato specific ADH-1 homodimers were synthesized as well as heterodimers composed of tobacco and tomato subunits.
