Abstract
Using agarose gel electrophoresis and T4-endodeoxyribonuclease-V, which is a kind of restriction endonuclease of cyclobutyl pyrimidine dimer (CPD), the impacts of He-Ne laser (5 mW (.) mm(-2)) irradiation on DNA excision repair capacity in damaged wheat cells induced by enhanced ultraviolet-B (10.08 kJ (.) m(-2 .) d(-1)) radiation were studied. The results indicated that the content of endonuclease sensitive sites (ESS) was reduced by He-Ne laser irradiation, which formed in cells irradiated by enhanced ultraviolet-B. With the irradiation of He-Ne laser, the excision of CPDs and the reduction of single strand breaks (SSB) contents which were the endonuclease sensitive sites (ESS) digested by T4-endodeoxyribonuclease-V had been stimulated in the wheat cells.
