Representative schematic model displaying the effect of heat stress on photosynthetic carbon metabolism and ROS scavenging system for both CfT lines (PS and SG). Cells in gradient colors represent the relative ratio of proteins or values of physiological parameters in PS and SG CfT lines exposed to heat stress. Regarding the model, most of pathways (carbon metabolism, photorespiration and ROS scavenging system) operate in synergy (fold of change was mostly higher than 4 for all sites), which potentially reflects the high protection and resistance of PS line to heat stress. However, for SG line, except the photorespiration metabolism (fold of change between 1~2), all the other sites were down regulated and this very likely could be the reason of the high vulnerability of SG to heat.
