Mitochondrial alternative oxidase pathway acts as an electron sink during photosynthetic induction in Rumex K-1 leaves

Photosynthetica, 2021
Chloroplast PSII photochemical efficiency is upregulated more rapidly than CO2 assimilation during photosynthesis induction, suggesting the existence of other electron sinks than that of CO2 assimilation.

Fluorescence induction of photosynthetic bacteria [PDF]

Photosynthetica, 2018
The kinetics of bacteriochlorophyll fluorescence in intact cells of the purple nonsulfur bacterium Rhodobacter sphaeroides were measured under continuous and pulsed actinic laser diode (808 nm wavelength and maximum 2 W light power) illumination on the micro- and millisecond timescale.

Short-term elevated temperature and CO2 promote photosynthetic induction in the C3 plant Glycine max, but not in the C4 plant Amaranthus tricolor.

Functional Plant Biology, 2022
The continuous increases of atmospheric temperature and CO2 concentration will impact global photosynthesis. However, there are few studies considering the interaction of elevated temperature (eT) and elevated CO2 (eCO2) on dynamic photosynthesis ...

Contributions of species shade tolerance and individual light environment to photosynthetic induction in tropical tree seedlings.

Tree Physiology, 2022
It has long been debated whether tree leaves from shady environments exhibit higher photosynthetic induction efficiency than those from sunny environments and how the shade tolerance of tree species and the light environment of leaves contribute to the ...

Photosystem II Photosynthetic Unit Sizes from Fluorescence Induction in Leaves [PDF]

Plant Physiology, 1981
The use of fluorescence induction measurements in leaves infiltrated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea has been evaluated as a routine method for estimation of the concentration of the reaction centers of photosystem II relative to total chlorophyll in a wide variety of plant species. The procedure is based on a simple theory that takes into

Drought stress reduces crop carbon gain due to delayed photosynthetic induction under fluctuating light conditions.

Physiologia Plantarum : An International Journal for Plant Biology, 2021
Drought stress is a major limiting factor for crop growth and yield. Water availability in the field can cyclically change between drought and rewatering conditions, depending on precipitation patterns.

Elevated CO2 Enhances Dynamic Photosynthesis in Rice and Wheat

Frontiers in Plant Science, 2021
Crops developed under elevated carbon dioxide (eCO2) exhibit enhanced leaf photosynthesis under steady states. However, little is known about the effect of eCO2 on dynamic photosynthesis and the relative contribution of the short-term (substrate) and ...
