| 摘要 |
The invention relates to an expression cassette for expressing genes in plant seed and to the plasmids containing said expression cassette. The invention includes the production of transgenic plant cells containing said expression cassette and the use of the plasmids in said expression cassette for producing transgenic plants. The invention can be applied in the field of biotechnology, pharmaceutics and plant production. The aim of the invention is to provide a means for the seed-specific expression in transgenic plants in such a manner that it is suitable for the production of the desired substances. Another aim of the invention is to construct an expression cassette which allows stable expression of genes of substances to be produced in plant seed at a high expression rate. The inventive expression cassette comprises the following essential components: the promoter of the gene of the seed protein which is analogous to the sucrose binding protein (SBP), optionally the DNA sequence of a signal peptide, preferably that of the SBP signal peptide, a gene to be expressed, 3' termination sequences.
