Fig. 5From: Single-wall carbon nanotubes improve cell survival rate and reduce oxidative injury in cryopreservation of Agapanthus praecox embryogenic callusThe heat-map of ROS signal transduction and antioxidant system related genes in the control and the SWCNTs-added cryopreservation. The up-regulated genes are indicated in red, and the down-regulated genes are indicated in green. The intensity of the colors increases as the expression differences increase, as shown in the bar at the bottom. CK, untreated; PC, after pre-culture; DH, after dehydration; RW, after rapid cooling-warming; DL, after dilutionBack to article page
