Studies on Mechanism of Kinetin Promoted SOD Biosynthesis of Rice Seedlings after Chilling Injury
摘要
Abstract
Experiments showed that exogenous KT(2 mg·L-1) can increase SOD activity of rice seedlings after chilling injury, but the SOD activity of normal rice seedlings and its cell free extract did not increased with KT treatment. For study on mechanism of de novo SOD biosynthesis of seedling after chilling injury with KT treatement, transcription inhibitor actinomycin D(AMD, 3 mg·L-1) was used. The experiments showed that KT promoted SOD de novo biosynthesis mainly on the transciriptional level.关键词
