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

J Exp Bot. 2000 Apr;51(345):817-21.

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.
