Real-time PCR quantitative analysis of ROS signal transduction and antioxidant system related genes between the control and the SWCNTs-added cryopreservation. Bars show means of gene expression level and standard deviation over triplicate detections. Values with different lowercase letters are significantly different among samples in the control group at 0.05 level. Values with different uppercase letters are significantly different among samples in the SWCNTs group at 0.05 level. * are significantly different between different groups in the same stage at 0.05 level, and ** are highly significantly different between different groups in the same stage at 0.01 level. The CK group is the cryopreservation without adding SWCNTs, and the CNT group is the SWCNTs-added cryopreservation. CK, untreated; PC, after pre-culture; DH, after dehydration; RW, after rapid cooling-warming; DL, after dilution
