Photosynthesis of Grass Species Differing in Carbon Dioxide Fixation Pathways 1doi:10.1104/pp.67.3.433Panicum species of the Laxa group were investigated in a series of published reports and were found to posses
A team led by researchers at the University of California, Davis, has discovered a missing link in the evolution ofphotosynthesisand carbon fixation. Dating back more than 2.4 billion years, a newly discovered form of the plant enzyme rubisco could give new insight into plant evolution and breedi...
photosynthesis in a marine diatom Nearly 50 years ago, inorganic carbon was shown to be fixed in microalgae as the Ccompound phosphoglyceric acid. The enzyme responsible for Ccarbon fixation, ribulose-1,5-bisphosphate carboxylase (Rubisco), however, requires inorganic ca... John R. Reinfelder,Ann...
The current generation of Earth system models used by the United Nations to project future climate scenarios (CMIP6) relies heavily on marine biogeochemical models to track the fate of carbon absorbed into the oceans. Here we compare 11 CMIP6 marine biogeochemical models and find the largest sourc...
Light capture and light energy conversion are critical steps for bacterial photosynthesis. Among these, solar-to-chemical energy conversion is a process with high energy loss and a low utilization rate, which limits for accommodating a potentially strong carbon sink in downstream pathway engineering. ...
The maximum influence of carbon fixation on the isotopic composition of the cytosolic pool, and thus on the coccolith vesicle and calcite, therefore occurs at intermediate values of CO2 utilization in the chloroplast (Fig. 4). Taken to either limit; zero; and complete utilization, carbon fixation...
We observed high transcriptional activity of Thaumarchaeota in the deoxygenated waters, with significant increase in the expression of core genes representing ammonia oxidation, ammonia transport, and carbon fixation pathways. Meanwhile, the transcripts of Cyanobacteria (particularly for photosynthesis and ca...
Step-by-Step Solution:1. Understanding Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide (CO2) and wat
Metabolic pathways such as “photosynthesis”, “photosynthesis-antenna proteins”, and “carbon fixation in photosynthetic organisms”, were closely associated with photosynthesis, while “α-linoleic acid metabolism” and “fatty acid metabolism” were closely related to lipid metabolism (Fig. 5b). To...
To better understand electron flow during EEU we pursued a chemical probe-based approach to selectively inhibit key proteins involved in cyclic pETC. TIE-1 and related anoxygenic phototrophs use cyclic photosynthesis30to generate energy (Fig.2). The photosystem (P870) is reported to be at the...
