[48]. PTOX has also been implicated in growing the flux through the linear Etc. and subsequent increased tolerance of photosystems to high light in cold-hardened Arabidopsis thaliana [49]. This result suggests that the energy dissipation mechanisms set in motion within the chloroplast in the course of winter hardening have been successful. A single manifestation of this may have been a fairly low amount of ROS generation as the temperature dropped. Having said that, redox effects on cellular responses to the atmosphere are certainly not confined to a simple containment of ROS. A great deal information point to regulatory roles for precise antioxidant proteins in plant cells beneath strain. A number of of these antioxidant, regulatory genes have been upregulated over the winter hardening time course, such as catalase CAT2, glutaredoxin ROXY1, and glutathioneCollakova et al.
