PROMOTER SEQUENCE WHICH IS EXPRESSED IN ANTHERS AND IN POLLEN

摘要

An expression cassette for expression in plants which allows a heterogenous gene to be specifically expressed in anthers and/or pollen is provided. This expression cassette contains a rice CatA gene promoter having a sequence shown as SEQ ID NO: 1, or a sequence which includes a portion thereof and which has a promoter activity equivalent to that of the sequence shown as SEQ ID NO: 1, and a site for inserting a heterogenous gene such that the heterogenous is expressibly linked to the promoter. A recombinant plasmid containing a heterogenous gene, and a method for introducing a heterogenous gene into a plant by using a recombinant plasmid are also provided.
