Diurnal change of cucumber CPD photolyase gene (CsPHR) expression and its physiological role in growth under UV-B irradiation.

Abstract excerpt

Complementary DNA encoding a putative cyclobutane pyrimidine dimer (CPD)-specific DNA photolyase (CPD photolyase) was isolated from cucumber leaves. The deduced amino acid sequence of the cDNA exhibited high similarity to that of the Arabidopsis CPD photolyase. Transformation with the cDNA restored the impaired photorepair activity of an Escherichia coli mutant, indicating that this cDNA encodes a functional...
