| Abstract: | A 577-bp promoter segment of Agrobacterium rhizogenes rolC, previously known as the phloem-specific gene expression promoter, was fused to the 5′ end of a reporter gene, β-glucuronidase
(GUS), uidA. This rolC-promoter-driven expression of the GUS gene was found to be significantly strong in glandular cells in transgenic tobacco plants. Analysis of this segment of the
promoter sequence revealed a myb response element. |
