By: S. Huber n & K. Hanson

TL;DR: The photosynthetic carbohydrate metabolism and growth of a starchless mutant of Nicotiana sylvestris that is deficient in plastid phosphoglucomutase is characterized and restricted growth of the mutant on short days is postulated, including slightly lower net photosynthesis and inability to synthesize starch in both source and sink tissues for use at night.

By: S. Huber n, J. Huber, W. Campbell & M. Redinbaugh

TL;DR: Overall, NR and SPS share many common features of control but are not identical in terms of regulation in situ, whereas with NR, the covalent modification is super-imposed on changes in the level of NR protein. (via Semantic Scholar)
