<p>A DNA being derived from a gene encoding rice adenylate kinase and exerting a promoter function in a plant body; a vector carrying the DNA having the promoter function; a bacterium containing the vector; a plant cell transformed by the vector; and a regenerated plant obtained from this cell and its seed. The above DNA having the promoter function can be ligated to a structural gene such as a reporter gene and integrated into a vector such as an expression vector. When the DNA having the promoter function is ligated to a vector together with a structural gene encoding a protein and a host plant is transformed thereby, the structural gene is expressed. Further, the expression of a desired structural gene can be regulated by ligating the desired gene under the control of the DNA fragment.</p> |
