Gene of enzyme reactivating dna damaged by ultraviolet light using visible light

摘要

It is intended to contribute to the solution of environmental problems caused by destroying the ozone layer and serious problems concerning the food resources in the 21st century by isolating a photoreactivating enzyme from an ultraviolet light-tolerant rice plant, thus acquiring information on the photoreactivation mechanism of the plant which still remains unknown mostly, and constructing an ultraviolet light-tolerant plant with the use of a cloned gene. Genes encoding a photoreactivating enzyme originating in rice plant, in particular, a gene encoding a protein as specified in the following (a) or (b): (a) a protein comprising the amino acid sequence represented by SEQ ID NO:1; and (b) a protein comprising an amino acid sequence derived from the amino acid sequence (a) by deletion, substitution or addition of one to several amino acids and having a photoreactivating enzyme activity.
