However, as yet only one putative transcription factor, WF-1, present in wheat leaf nuclei, has been identified as interacting with an SBPase gene upstream sequence (Miles et al. 1993). The activity of the SBPase enzyme is regulated by light. On transfer from darkness to light, the catalytic ...
WebbIn plant photosynthesis, the energy of light is used to drive the oxidation of water (H 2 O), producing oxygen gas (O 2), hydrogen ions (H +), and electrons. Most of the removed electrons and hydrogen ions ultimately … WebbAs light availability decreases deeper in the water column, photosynthesis rates also decrease, and less dissolved oxygen is produced. This means that dissolved oxygen concentrations generally decrease as you move deeper into the body of water because of photosynthesis is not replenishing dissolved oxygen that is being taken up through …
