Abstract:Transgenic tobacco plants possessing a chimeric gene of thepromoter region of the Ri plasmid ORF12 gene (rolC) and a structuralgene of bacterial ß-glucuronidase were obtained. Histochemicalanalysis showed that the chimeric gene is expressed in phloemcells throughout whole plants. Stable inheritance of such cellspecific expression of ORF12 promoter was also confirmed. 2Present address: Research Institute of Agricultural Resources,Ishikawa Agricultural College, Nonoichi-machi, Ishikawa, 921Japan.
