Regulated genes in transgenic plants.

Journal Article (Journal Article)

Transgenic plants are an effective system for the study of regulated gene expression. Developmental control of expression can be monitored by assaying different tissues or by assaying a plant at different developmental stages. Analysis of the petunia 5-enolpyruvylshikimate-3-phosphate synthase gene, which is highly expressed in flowers, allowed identification of an upstream region that confers tissue-specific and developmentally regulated expression. The cell specificity of expression in floral tissues has been defined by histochemical localization. This expression is contrasted to that of the 35S promoter of cauliflower mosaic virus, a nominally constitutive promoter that shows a definite specificity of expression in floral tissues. Moreover, this expression differs in transgenic hosts of different species.
