Another two genes controlling mitotic intragenic recombination and recovery from UV damage in Aspergillus nidulans III. Photoreactivition of UV damage in uvsD and uvsE mutants

Abstract

In this paper photoreactivation of UV damage in growing uvs+, uvsD53 and uvsE82 conidia of Aspergillus nidulans is examined. The results indicate that uvs+ and uvsE82 conidia immediately start to lose photoreactivable lesions following incubation in the dark, but that uvsD53 conidia retain these lesions for at least several hours. The observations are interpreted as indicating that uvs+ and uvsE82 conidia are excision-efficient but that uvsD53 is defective in excision repair.
