Do metabolite transport processes limit photosynthesis?
Metabolite transport proteins occupy key positions in the metabolic networks of highly compartmentalized eukaryotic cells. In such cells, at least one and frequently more than one membrane delineate organelles from the cytosol. Thereby compartments with different reactions milieus are created that are characterized by low pH or high-energy status, or by highly reductive or oxidative conditions,...
متن کاملC4 photosynthesis
The question then is how the same neurons convey two different sorts of information. The answer is that motor giants are capable of generating two types of action potentials, small/slow calcium spikes and large/fast sodium spikes, depending on the degree of depolarization it receives. As opposed to the input from the ring giant, the input from the pacemaker is too low to trigger the sodium spik...
متن کاملThe inevitability of C4 photosynthesis
Elements of C4 photosynthesis-a complex adaptation that increases photosynthetic efficiency-may have evolved first to correct an intercellular nitrogen imbalance, and only later evolved a central role in carbon fixation.
متن کاملPhotosynthesis in C3-C4 intermediate Moricandia species.
Evolution of C4 photosynthesis is not distributed evenly in the plant kingdom. Particularly interesting is the situation in the Brassicaceae, because the family contains no C4 species, but several C3-C4 intermediates, mainly in the genus Moricandia Investigation of leaf anatomy, gas exchange parameters, the metabolome, and the transcriptome of two C3-C4 intermediate Moricandia species, M. arven...
متن کاملDoes C4 Photosynthesis Occur in Wheat Seeds?
Our recent report of new evidence for C4 photosynthesis in wheat seeds (Rangan et al., 2016) has been met with skepticism (Busch and Farquhar, 2016), maybe because this has been such a long-running controversy. Much of the confusion has been because early work did not distinguish photosynthesis in the pericarp of the seed (Fig. 1) from that in the covering glumes. Glumes, like leaves in wheat, ...
