| To understand the properties of the cauliflower mosaic virus (CaMV) 35S promoter and the effect of the deleted maize alcohol dehydrogenase I-S (Adhl-S) intron 1 on the expression of the CaMV $35S{eta}-glucuronidase$ (GUS) gene in potato (Solanum tuberosum L. cv. Superior), we constructed a chimeric gene and transferred it into potato with Agrobacterium tumefaciens mediated method. The pLS201, a gene transfer vector of 17.7 kilobase pairs, was composed of the CaMV 35S promoter, the 249 base pairs of deleted maize Adhl-S intron 1, the GUS reporter gene, and the kanamycin resistance gene as a selectable marker for transformation. The GUS activity was examined by histochemical and spectrophotometric assay in transformed potato plants. The GUS activity was found primarily around the vascular tissue cells in stem and root. In the spectorophotometric assay, the level of GUS activity of transgenic potato transformed with CaMV 35S/249 bp of intron 1 fragment-GUS (pLS201) was compared with that of potato transformed with CaMV 35S-GUS (pBI121). The quantitative spectrophotometric assay showed that the level of GUS activity in potato transformed with pLS201 was higher in leaf, stem and root by 30-, 34- and 42-fold, respectively than those in potato transformed with pBI121. This results indicate that the inclusion of the deleted maize Adhl-S intron 1 resulted in increament of the GUS gene expression in transgenic potato.potato. |
