The Path of Carbon in Photosynthesis. XVI. Kinetic Relationshipsof the Intermediates in Steady State Photosynthesis [PDF]

open access: yes, 1952
A kinetic study of the accumulation of C{sup 14} in the intermediates of steady state photosynthesis in C{sup 14}O{sub 2} provides information regarding the sequence of reactions involved. The work described applied the radio-chromatographic technique for analysis of the labeled early products. The simultaneous carboxylation reaction resulting in malic

NTRC Effects on Non-Photochemical Quenching Depends on PGR5

open access: yesAntioxidants, 2021
Non-photochemical quenching (NPQ) protects plants from the detrimental effects of excess light. NPQ is rapidly induced by the trans-thylakoid proton gradient during photosynthesis, which in turn requires PGR5/PGRL1-dependent cyclic electron flow (CEF ...

Measuring the dynamic photosynthome [PDF]

open access: yes, 2018
Background: Photosynthesis underpins plant productivity and yet is notoriously sensitive to small changes inenvironmental conditions, meaning that quantitation in nature across different time scales is not straightforward.

Photosynthetic Characteristics of Antisense Transgenic Rice Expressing Reduced Levels of Rubisco Activase

open access: yesPlant Production Science, 2012
The activation of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), which catalyses CO2 fixation in photosynthesis, requires the assistance of the regulatory protein Rubisco activase.

The Path of Carbon in Photosynthesis. XX. The Steady State [PDF]

open access: yes, 1952
The separation of the phenomenon of photosynthesis in green plants into a photochemical reaction and into the light-dependent reduction of carbon dioxide is discussed, The reduction of carbon dioxide and the fate of the assimilated carbon were investigated with the help of the tracer technique (exposure of the planks to the radioactive C{sup 14}O{sub 2}

Light energy allocation at PSII under field light conditions: How much energy is lost in NPQ-associated dissipation? [PDF]

open access: yes, 2014
In the field, plants are exposed to fluctuating light, where photosynthesis occurs under conditions far from a steady state. Excess energy dissipation associated with energy quenching of chlorophyll fluorescence (qE) functions as an efficient photo ...

Leaf Gas Exchange and Photosystem II Fluorescence Responses to CO2 Cycling

open access: yesPlants, 2023
Experimental systems to simulate future elevated CO2 conditions in the field often have large, rapid fluctuations in CO2. To examine possible impacts of such fluctuations on photosynthesis, the intact leaves of the field-grown plants of five species were

The diurnal time course of net photosynthesis of soybean leaves: Analysis with a physiologically based steady-state photosynthesis model [PDF]

open access: yesOecologia, 1980
A physiologically based steady-state model of whole leaf photosynthesis (WHOLEPHOT) is used to analyze observed net photosynthesis daily time courses of soybean, Glycine max (L.) Merr., leaves. Observations during two time periods of the 1978 growing season are analyzed and compared.
