EXPRESSION CONTROL POLYNUCLEOTIDES

摘要

There is provided an expression control polynucleotide of an invertase gene, which may be operably limited to a heterologous polynucleotide. Optionally the expression control polynucleotide and heterologous polynucleotide construct is transfected into host cells or organisms. Preferably the construct is used to produce a transgenic plant and the expression control polynucleotide is pollen cell-specific. A suitable expression control polynucleotide is as set out in SEQ ID No 1, especially nucleotides 3430-5349 thereof. Desirably the protein expressed by the heterologous polynucleotide causes male sterility in the transgenic plants.
