Photosynthetic induction in C4 leaves
Planta, 1985Simultaneous measurements of CO2 uptake, transpiration rate, and chlorophyll a fluorescence in leaf strips of C4 plants during the induction phase of photosynthesis are described. The timecourse of CO2 fixation is biphasic with the initial phase occurring within the first 1 to 5 min and the secondary phase consisting of a slow rise to the steady-state ...

Reduced minimum model for the photosynthetic induction processes in photosystem I
Journal of Photochemistry and Photobiology B: Biology, 2016Photosystem I (PS I) is one of the most important protein complexes for photosynthesis, which is present in plants, algae and cyanobacteria. A variety of mechanisms for environmental response in and around PS I have been elucidated experimentally and theoretically.

Chloroplast Energization During Photosynthetic Induction
1987Although photosynthetic induction [1] and fluorescence induction (Kautsky effect) are not synonymous, experimental evidence indicates that fluorescence kinetics are closely related to the complexities of induction and its termination. Early studies of chlorophyll fluorescence kinetics in a physiological context were mainly descriptive (for reviews see ...

Early detection of mercury contamination by fluorescence induction of photosynthetic bacteria
Photochemical & Photobiological Sciences, 2010The induction (sudden dark-to-light transition) of fluorescence of photosynthetic bacteria has proved to be sensitive tool for early detection of mercury (Hg(2+)) contamination of the culture medium. The major characteristics of the induction (dark, variable and maximum fluorescence levels together with rise time) offer an easier, faster and more ...

Fluorescence Induction in Photosynthetic Bacteria
1972Many experiments were in favor of the assumption that the Kautsky effect may be attributed to electron exchange reactions between the photosystem II and the redox chain leading to photosystem I.That means the cooperation between two photoreactions should be responsible for the induction phenomena.

Photosynthetic induction of dual phosphate uptake kinetics inPorphyra umbilicalis
Physiologia Plantarum, 1994The rates of phosphate uptake and photosynthesis were simultaneously determined in order to investigate the relationship between phosphate use and photosynthesis.Porphyra umbilicalis(L.) Kützing exhibited two different phosphate uptake kinetics. The first one followed a saturation model and was observed in light (maximum phosphate uptake rate. Vmax= 94

Primary Photosynthetic Induction Phenomena in Wheat
Physiologia Plantarum, 1967AbstractThe induction phenomena of photosynthesis in leaves of wheat were studied with a Beckman oxygen sensor. By special treatment prior to illumination, e.g. long dark and anaerobic periods the oxygen evolution could be divided into two parts, one consisting of two or three transients appearing under the first minute of illumination and one ...

Induction of Photosynthetic Oxygen Evolution in Spinach Leaves
1984When leaves are illuminated, the rate of oxygen evolution does not immediately reach its maximum steady state value. The time between the onset of illumination and the attainment of this maximum steady state rate is called the induction period. Induction in chloroplasts has been extensively studied (for review see Walker,1981) but this knowledge has ...

Natural genetic variation of the photosynthetic induction response to fluctuating light environment
Current Opinion in Plant Biology, 2019Field-grown plants experience fluctuating light intensity for periods extending from seconds to hours because of cloud movements and self-shading. When full light intensity returns after shading, the net CO2 assimilation rate in leaves does not reach its maximum value immediately, but rises gradually over several minutes to approach a new steady state.

Photosynthesis Research, 2017
Plants grown in the field experience sharp changes in irradiation due to shading effects caused by clouds, other leaves, etc. The excess of absorbed light energy is dissipated by a number of mechanisms including cyclic electron transport, photorespiration, and Mehler-type reactions. This protection is essential for survival but decreases photosynthetic
