CA Case GA/5-17740/= Regulatory DNA sequence Abstract The present invention relates to a novel, substantially pure, regulatory DNA sequence that is obtainable from the 5' region of a plant chitinase gene and that, in operable linkage with any desired expressible DNA, leads to greatly increased levels of expression in transformed plants. The present invention relates also to recombinant DNA molecules that contain the DNA sequence according to the invention in operable linkage with an expressible DNA, and to the vectors derived therefrom, and also to host cells and/or host organisms, including transgenic plants, that contain the said recombinant DNA or the vectors derived therefrom. The present invention also includes a novel chitinase gene that is obtainable from Nicotiana tabacum L. c.v. Havana 425 plants and that contains in its 5' untranslated region the regulatory DNA sequence according to the invention. |
