Ort, Donald R. Tucker, Dawn Elizabeth 2015-09-28T15:22:38Z 2015-09-28T15:22:38Z 10000-01-01 2001 2001 The similarity in regulation between NR and sucrose phosphate synthase suggested that NR might be subject to low temperature disruptions in its endogenous rhythm as has been demonstrated for SPS in chilling-sensitive species such as tomato. NR regulation is in fact disrupted by low temperatures, however the change is transient and does not alter the phase of the NR endogenous rhythm following the chill. NR rather undergoes a temporary induction of de novo transcription regardless of the time in the circadian cycle that the chilling episode is initiated causing an increase in both NR protein and activity. The untimely depletion of reductant and TCA carbon skeletons as well as accumulations of toxic byproducts of nitrogen assimilation that this would cause is likely to be detrimental to the plant.
