Identification of two forms of PFK and a fructose-2,6-bisphosphate independent form of PFP in a green algaPhotosynthesis Research - Tập 21 Số 2 - Trang 123-128 - 1989
Kiss, F., Johnson, T. C., Klecan, A. L., Vincze, Gy., Buchanan, B. B., Balogh, A.
Cell-free preparations from the green alga, Chlorella pyrenoidosa, contained two forms of phosphofructokinase (PFK), designated PFK I and PFK II. This represents the first evidence for a second form of PFK in green algae. A pyrophosphate D-fructose-6-phosphate, 1-phosphotransferase (PFP) activity, that was unaffected by the regulatory metabolite, fructose-2,6-bisphosphate, co-purified with PFK II ...... hiện toàn bộ
Light and growth temperature alter carbon isotope discrimination and estimated bundle sheath leakiness in C4 grasses and dicotsPhotosynthesis Research - Tập 91 - Trang 47-58 - 2007
Jiří Kubásek, Jiří Šetlík, Simon Dwyer, Jiří Šantrůček
We combined measurements of short-term (during gas exchange) and long-term (from plant dry matter) carbon isotope discrimination to estimate CO2 leakiness from bundle sheath cells in six C4 species (three grasses and three dicots) as a function of leaf insertion level, growth temperature and short-term irradiance. The two methods for determining leakiness yielded similar results (P > 0.05) for all...... hiện toàn bộ
An integration of photosynthetic traits and mechanisms that can increase crop photosynthesis and grain productionPhotosynthesis Research - Tập 46 - Trang 169-175 - 1995
C. C. Black, Z. P. Tu, P. A. Counce, P.-F. Yao, M. N. Angelov
The hypothesis we propose is that during photosynthesis the balance between potentially detrimental and beneficial photochemically induced events can be tipped beneficially toward increased photosynthesis and toward increased crop yield. To test this hypothesis a procedure has been devised with the rice plant, Oryza sativa, that has resulted in increasing both canopy photosynthesis and rice grain ...... hiện toàn bộ
Coupling biology to synthetic nanomaterials for semi-artificial photosynthesisPhotosynthesis Research - Tập 143 Số 2 - Trang 193-203 - 2020
Brown, Katherine A., King, Paul W.
Biohybrid artificial photosynthesis aims to combine the advantages of biological specificity with a range of synthetic nanomaterials to create innovative semi-synthetic systems for solar-to-chemical conversion. Biological systems utilize highly efficient molecular catalysts for reduction–oxidation reactions. They can operate with minimal overpotentials while selectively channeling reductant e...... hiện toàn bộ
Ca2+ effects on Fe(II) interactions with Mn-binding sites in Mn-depleted oxygen-evolving complexes of photosystem II and on Fe replacement of Mn in Mn-containing, Ca-depleted complexesPhotosynthesis Research - Tập 147 Số 2 - Trang 229-237 - 2021
Semin, B. К., Davletshina, L. N., Goryachev, S. N., Seibert, M.
Fe(II) cations bind with high efficiency and specificity at the high-affinity (HA), Mn-binding site (termed the “blocking effect” since Fe blocks further electron donation to the site) of the oxygen-evolving complex (OEC) in Mn-depleted, photosystem II (PSII) membrane fragments (Semin et al. in Biochemistry 41:5854, 2002). Furthermore, Fe(II) cations can substitute for 1 or 2Mn cations (pH depende...... hiện toàn bộ
