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 ...

An Ecohydrological Perspective on Drought-induced Forest Mortality [PDF]

, 2014
Regional‐scale drought‐induced forest mortality events are projected to become more frequent under future climates due to changes in rainfall patterns. The occurrence of these mortality events is driven by exogenous factors such as frequency and severity

The Energy Budget of Steady-State Photosynthesis [PDF]

, 2007
Our work developed a unique set of in vivo spectroscopic tools that have allowed us to probe the importance of 1) The effects of storage of proton motive force (pmf ) in the form of both electric field (Δψ) and pH difference (ΔpH); 2) alteration in the stoichiometry of proton pumping to electron transfer at key steps; 3) the influence of changes in the

CpLEPA is critical for chloroplast protein synthesis under suboptimal conditions in Arabidopsis thaliana. [PDF]

PLoS ONE, 2012
LEPA is one of the most conserved translation factors and is found from bacteria to higher plants. However, the physiological function of the chloroplast LEPA homolog in higher plants remains unknown.

Non-steady-state stomatal conductance modeling and its implications: from leaf to ecosystem [PDF]

Biogeosciences
Accurate and efficient modeling of stomatal conductance (gs) has been a key challenge in vegetation models across scales. Current practice of most land surface models (LSMs) assumes steady-state gs and predicts stomatal responses to environmental cues as

High Stomatal Conductance in the Tomato Flacca Mutant Allows for Faster Photosynthetic Induction

Frontiers in Plant Science, 2020
Due to their slow movement and closure upon shade, partially closed stomata can be a substantial limitation to photosynthesis in variable light intensities.

Effects of measurement methods and growing conditions on phenotypic expression of photosynthesis in seven diverse rice genotypes

Frontiers in Plant Science, 2023
IntroductionLight response curves are widely used to quantify phenotypic expression of photosynthesis by measuring a single sample and sequentially altering light intensity within a chamber (sequential method) or by measuring different samples that are ...

Carboxylation Capacity Can Limit C₃ Photosynthesis at Elevated CO₂ throughout Diurnal Cycles

Plants, 2021
The response of carbon fixation in C3 plants to elevated CO2 is relatively larger when photosynthesis is limited by carboxylation capacity (VC) than when limited by electron transport (J). Recent experiments under controlled, steady-state conditions have

Elevated CO₂ does not increase eucalypt forest productivity on a low-phosphorus soil [PDF]

, 2017
Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions. Elevated CO2 experiments in temperate planted forests yielded ~23% increases in productivity over the initial years.
