It is intended to contribute to the solution of environmental problems caused byndestroying the ozone layer and serious problems concerning the food resources in then21 st century by isolating a photoreactivating enzyme from an ultraviolet light-tolerantnrice plant, thus acquiring information on the photoreactivation mechanism of the plantnwhich still remains unknown mostly, and constructing an ultraviolet light-tolerant plantnwith the use of a cloned gene. Genes encoding a photoreactivating enzyme originatingnin rice plant, in particular, a gene encoding a protein as specified in the following (a) orn(b): (a) a protein comprising the amino acid sequence represented by SEQ ID NO:1; andn(b) a protein comprising an amino acid sequence derived from the amino acid sequencen(a) by deletion, substitution or addition of one to several amino acids and having anphotoreactivating enzyme activity. |
