Abstract
The cloning of promoter sequences of two invertase genes from potato (Solanum tuberosum L.) is described. Histochemical analysis of series of reporter transgenic lines reveals phloem-specific expression from both promoters, with one expressed preferentially in internal phloem and the other in external phloem of stem vascular bundles.
