Deletion Analysis of the 5'-Upstream Region of the Agrobacterium rhizogenes Ri Plasmid rolC Gene Required for Tissue-Specific Expression.
The cis-acting elements located in the -848 and +23 region of the 5'-upstream region of the rolC gene of the Agrobacterium rhizogenes Ri plasmid were investigated. The cis-acting DNA region required for phloem-specific expression was found within the -153 region, whereas a minimum region needed for the expression in the seed embryo was located at position -120.
