Abstract

NADPH-dependent thioredoxin reductase C (NTRC) redox interaction with protein CP12 plays a role in cold acclimation. A recent study by Teh et al. describes the underlying molecular mechanisms that leads to dissociation of the autoinhibitory PRK/CP12/GAPDH (phosphoribulokinase/CP12/glyceraldehyde-3-phosphate dehydrogenase) supracomplex. We propose that chloroplast-to-nucleus retrograde signaling precedes the described mechanism.
