The technique of chlorophyll-a fluorescence induction (ChlF) is widely used in plant biology. The 'mainstream', so-called QA model of ChlF, posits that the reaction centers (RCs) of Photosystem-II (PSII) exist in two states, quenched (Fo) o...

Hiroo Takaragawa et al.
Leaf photosynthetic rate serves as a growth indicator in plant science; however, the high cost (exceeding USD 70,000) of traditional measurement system is the main concern when making photosynthesis measurements of interest to a wide range ...
Time-resolved targeted metabolomics shows an abrupt switch from Calvin-Benson-Bassham cycle to tricarboxylic acid cycle when the light is turned off [0.03%]
时间分辨靶向代谢组学表明，在关灯时Calvin-Benson-Bassham循环会突然转变为三羧酸循环

In leaves, major CO₂ fluxes alternate between fixation by the Calvin-Benson-Bassham (CBB) cycle during light and release by the tricarboxylic acid (TCA) cycle in darkness. The speed at which leaf metabolism transitions between these pathwa...
Modulation of singlet excited state dynamics of bacteriochlorophyll a in Fenna-Matthews-Olson (FMO) complex by PscB, a subunit with an intrinsically disordered region in Chlorobaculum tepidum reaction center [0.03%]

Anica Dadwal et al.
Modulation of the chlorophyll singlet state by protein environment is a key aspect of photosynthesis and light-harvesting in biological systems. This modulation affects excited-state dynamics, energy transfer efficiency, and photochemical r...
Thermoluminescence can be used to study lipid peroxidation in photosynthetic organisms [0.03%]
可利用热发光研究光合生物中的脂质过氧化作用

José M Ortega
Oxidants attack lipids with carbon-carbon double bonds, causing the formation of lipid peroxyl radicals and hydroperoxides through a process called lipid peroxidation. Different aldehydes, including malondialdehyde, can also be formed as se...
