<;P>;PROBLEM TO BE SOLVED: To provide a DNA having promotor activity bringing a leaf-specific expression, a recombinant plasmid containing the DNA and enabling the leaf-specific expression of an objective gene, and a transformed plant body introduced with the recombinant vector. <;P>;SOLUTION: This DNA functioning as a promotor, shown by the following (a), (b) or (c) is provided. (a) The DNA includes a specific base sequence. (b) The DNA includes a base sequence obtained by deleting, substituting or adding one or several bases in the specific base sequence, and has the promotor activity bringing the leaf-specific expression. (c) The DNA includes a base sequence having &ge;95% homology to the specific base sequence and has the promotor activity bringing the leaf-specific expression. <;P>;COPYRIGHT: (C)2010,JPO&INPIT
