An improved model of C3 photosynthesis at high CO2: Reversed O2 sensitivity explained by lack of glycerate reentry into the chloroplast
Photosynthesis Research - - 1991
Hydrogen peroxide generation and antioxidant enzyme activities in the leaves and roots of wheat cultivars subjected to long-term soil drought stress
Photosynthesis Research - Tập 125 - Trang 279-289 - 2015
The dynamics of the activity of catalase, ascorbate peroxidase, guaiacol peroxidase, and benzidine peroxidase, as well as the level of hydrogen peroxide in the vegetative organs of durum wheat (Triticum durum Desf.) cultivars was studied under long-term soil drought conditions. It was established that hydrogen peroxide generation occurred at early stages of stress in the tolerant variety Barakatli......
Identification of two forms of PFK and a fructose-2,6-bisphosphate independent form of PFP in a green alga
Photosynthesis Research - Tập 21 Số 2 - Trang 123-128 - 1989
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 ......
Light and growth temperature alter carbon isotope discrimination and estimated bundle sheath leakiness in C4 grasses and dicots
Photosynthesis Research - Tập 91 - Trang 47-58 - 2007
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......
Active in situ and passive airborne fluorescence measurements for water stress detection on a fescue field
Photosynthesis Research - Tập 155 - Trang 159-175 - 2022
Ledflex is a fluorometer adapted to measure chlorophyll fluorescence at the canopy level. It has been described in detail by Moya et al. (2019), Photosynthesis Research.

An integration of photosynthetic traits and mechanisms that can increase crop photosynthesis and grain production
Photosynthesis Research - Tập 46 - Trang 169-175 - 1995
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 ......
Coupling biology to synthetic nanomaterials for semi-artificial photosynthesis
Photosynthesis Research - Tập 143 Số 2 - Trang 193-203 - 2020
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......
Uncovering channels in photosystem II by computer modelling: current progress, future prospects, and lessons from analogous systems
Photosynthesis Research - Tập 98 - Trang 503-522 - 2008
Even prior to the publication of the crystal structures for photosystem II (PSII), it had already been suggested that water, O2 and H+ channels exist in PSII to achieve directed transport of these molecules, and to avoid undesirable side reactions. Computational efforts to uncover these channels and investigate their properties are still at early stages, and have so far only been based on the stat......
Comparative analysis of the primary structure of the reaction center-bound cytochrome subunit in purple bacteria
Photosynthesis Research - Tập 55 - Trang 349-355 - 1998
The amino acid sequences of the reaction center-bound cytochrome subunit of six species of purple bacteria were compared. Amino acid residues thought to be important in controlling the redox midpoint potentials of four hemes in Blastochloris (Rhodopseudomonas) viridis were found to be well conserved. As opposed to all other species studied, the amino acid sequence of the cytochrome subunit of B. v......
