Differential expression of invertase genes in internal and external phloem tissues of potato (Solanum tuberosum L.)

Show Summary Details

Preview

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‐expression from both promoters, with one expressed preferentially in internal phloem and the other in external phloem of stem vascular bundles.

Keywords: Promoter; source‐sink; vascular bundle.
