In transgenic plants, for many applications it is important that the inserted genes are expressed in a tissue-specific manner. This in turn could help better understanding their roles in plant development. Germin-like proteins (GLPs) play diverse roles in plant development and defence responses. In order to understand the functions and regulation of the GLP13 gene, its promoter (762 bp) was cloned and fused with beta-glucuronidase (GUS) reporter gene for transient expression in Arabidopsis thaliana and tobacco (Nicotiana tabacum cv. K326). Histochemical analysis of the transgenic plants showed that GUS was specifically expressed in vascular bundles predominantly in phloem tissue of all organs in Arabidopsis. Further analyses in transgenic tobacco also identified similar GUS expression in the vascular bundles.
