Intracellular position of mitochondria and chloroplasts in bundle sheath and mesophyll cells of C3 grasses in relation to photorespiratory CO2 loss

Plant Production Science, 2016
In C3 plants, photosynthetic efficiency is reduced by photorespiration. A part of CO2 fixed during photosynthesis in chloroplasts is lost from mitochondria during photorespiration by decarboxylation of glycine by glycine decarboxylase (GDC).

Thioredoxin system modulates metabolic and stomatal responses to elevated CO2 in Arabidopsis

New Phytologist, EarlyView.
Integrative model of extraplastidial NADPH‐dependent thioredoxin reductase/thioredoxin system‐mediated regulation of stomatal function, redox homeostasis, and metabolic responses under ambient and elevated CO2 in Arabidopsis thaliana. Summary The NADPH‐dependent thioredoxin reductase/thioredoxin (NTR/TRX) system plays a central role in maintaining ...

Environmental influences on the maximum quantum yield of terrestrial primary production

New Phytologist, EarlyView.
Temperature and aridity effects on terrestrial ecosystems' intrinsic quantum yield. Summary Historically, terrestrial biosphere models (TBMs) have assigned the intrinsic (maximum) quantum yield of photosynthesis (ϕ0)$$ {\phi}_0\Big) $$ a constant value for each plant functional type. However, experimental studies have shown that ϕ0$$ {\phi}_0 $$ – when

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Optimization of photosynthesis for sustainable crop production

CABI Agriculture and Bioscience, 2022
Crop production will need to increase by about 60% to satisfy the demand of food for the fast-growing population globally. A number of recent studies have provided strong support demonstrating that improving the photosynthetic efficiency via different ...

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Reconstruction of Oryza sativa indica Genome Scale Metabolic Model and Its Responses to Varying RuBisCO Activity, Light Intensity, and Enzymatic Cost Conditions

Frontiers in Plant Science, 2017
To combat decrease in rice productivity under different stresses, an understanding of rice metabolism is needed. Though there are different genome scale metabolic models (GSMs) of Oryza sativa japonica, no GSM with gene-protein-reaction association exist

Variation in Photorespiration. The Effect of Genetic Differences in Photorespiration on Net Photosynthesis in Tobacco [PDF]

Plant Physiology, 1968
The hypothesis that net photosynthesis is diminished in many plant species because of a high rate of CO(2) evolution in the light has been tested further. High rates of CO(2) output in CO(2)-free air in comparison with dark respiration were found in Chlamydomonas reinhardi, wheat leaves, tomato leaves, and to a lesser extent in Chlorella pyrenoidosa by

Concurrent Temperature and Light Intensity Fluctuations Promote Stomatal Opening and Non‐Steady State Photosynthesis

Plant, Cell &Environment, EarlyView.
ABSTRACT In nature, fluctuations in light intensity (FL) are tightly coupled to rapid changes in leaf temperature (Tleaf), yet the short‐term physiological effects of these concurrent drivers remain largely unresolved. Here, we combined rapid infrared induced Tleaf fluctuations with controlled step changes in light intensity for leaf gas exchange ...
