原始语种摘要: The base excision repair (BER) pathway is an essential defense mechanism in plants against oxidative damage of DNA. Previous studies have reported that chromium (Cr) exposure causes oxidative stress and DNA damage due to accumulation of reactive oxygen species (ROS). In this study, hydroponic experiments were carried out to investigate expression of 21 candidate genes involved in BER pathway in rice seedlings exposed to Cr(III) using qRT-PCR analysis. Changes of H2O2 and O2 content in rice tissues and the relative growth rate of rice seedlings were also determined. Results indicated that Cr(III) exposure caused dose-dependent inhibition on the relative growth rate of rice seedlings. H2O2 content in roots was significantly increased, while changes of H2O2 and O􀀀 2 content in shoots was...
