Deletion Analysis of the 5′-Upstream Region of the Agrobacterium rhizogenes Ri Plasmid rolC Gene Required for Tissue-Specific Expression

Abstract

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.
