Abstract

There is described a new DNA sequence of an expression cassette on which the potato tuber specific regulatory regions are localised as well as the transfer of this DNA sequence into the plant genome using agrobacteria as transfer micro-organisms. The DNA sequence contains a patatin gene with a patatin gene promoter. The transfer DNA sequence acts both for regulating endogenous as well as for preparation of heterologous products in crops.
