Updating the steady-state model of C4 photosynthesis [PDF]
Journal of Experimental Botany, 2021 Abstract C4 plants play a key role in world agriculture. For example, C4 crops such as maize and sorghum are major contributors to food production in both developed and developing countries, and the C4 grasses sugarcane, miscanthus, and switchgrass are major plant sources of bioenergy.

Rubisco activase is a key regulator of non‐steady‐state photosynthesis at any leaf temperature and, to a lesser extent, of steady‐state photosynthesis at high temperature [PDF]
The Plant Journal, 2012 SummaryThe role of Rubisco activase in steady‐state and non‐steady‐state photosynthesis was analyzed in wild‐type (Oryza sativa) and transgenic rice that expressed different amounts of Rubisco activase. Below 25°C, the Rubisco activation state and steady‐state photosynthesis were only affected when Rubisco activase was reduced by more than 70%. However,

Frontiers in Plant Science, 2017 Nitrogen is one of the most important elements for plants and is closely related to photosynthesis. High temperature stress significantly inhibits photosynthesis under both steady-state and flecked irradiance.

Steady‐state models of photosynthesis [PDF]
Plant, Cell & Environment, 2013 AbstractIn the challenge to increase photosynthetic rate per leaf area mathematical models of photosynthesis can be used to help interpret gas exchange measurements made under different environmental conditions and predict underlying photosynthetic biochemistry.

Modelling the role of Rubisco activase in limiting non‐steady‐state photosynthesis [PDF]
Journal of Experimental Botany, 2000 The roles of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase in limiting the approach of photosynthesis to steady-state following a step increase from a low to a saturating value of photon flux density (PFD) are reviewed. This information, along with the effect of Rubisco on steady-state photosynthetic rate and the effect

Remote Sensing of Environment, 2013 Previous studies have demonstrated the link between leaf chlorophyll fluorescence and photosynthesis, mainly at the leaf level and under controlled laboratory conditions. The present study makes progress in demonstrating the relationship between steady-state fluorescence and net photosynthesis measured under natural light field conditions both at the ...

Dynamics of photosynthetic induction and relaxation within the canopy of rice and two wild relatives
Food and Energy Security, 2021 Wild rice species are a source of genetic material for improving cultivated rice (Oryza sativa) and a means to understand its evolutionary history.

Photosynthetica, 2022 In nature, plants are often confronted with wide variations in light intensity, which may cause a massive carbon loss and water waste. Here, we investigated the response of photosynthetic rate and stomatal conductance to fluctuating light among ten rice ...

Analysis of Steady State Photosynthesis in Alfalfa Leaves [PDF]
Plant Physiology, 1976 A method for carrying out kinetic tracer studies of steady state photosynthesis in whole leaves has been developed. An apparatus that exposes whole leaves to (14)CO(2) under steady state conditions, while allowing individual leaf samples to be removed as a function of time, has been constructed. Labeling data on the incorporation of (14)C into Medicago
