Implication of quantifying nitrate utilization and CO2 assimilation of Brassica napus plantlets in vitro under variable ammonium/nitrate ratios [PDF]

open access: yesBMC Plant Biology, 2022
Background Plantlets grown in vitro with a mixed nitrogen source utilize sucrose and CO2 as carbon sources for growth. However, it is very difficult to obtain the correct utilization proportions of nitrate, ammonium, sucrose and CO2 for plantlets ...

Interaction of Nitrate Assimilation and Photorespiration at Elevated CO2

open access: yesFrontiers in Plant Science, 2022
It has been shown repeatedly that exposure to elevated atmospheric CO2 causes an increased C/N ratio of plant biomass that could result from either increased carbon or – in relation to C acquisition - reduced nitrogen assimilation.

Mitochondrial alternative oxidase pathway acts as an electron sink during photosynthetic induction in Rumex K-1 leaves

open access: yesPhotosynthetica, 2021
Chloroplast PSII photochemical efficiency is upregulated more rapidly than CO2 assimilation during photosynthesis induction, suggesting the existence of other electron sinks than that of CO2 assimilation.

Synthetic Formatotrophs for One‐Carbon Biorefinery

open access: yesAdvanced Science, 2021
The use of CO2 as a carbon source in biorefinery is of great interest, but the low solubility of CO2 in water and the lack of efficient CO2 assimilation pathways are challenges to overcome. Formic acid (FA), which can be easily produced from CO2 and more

Linking the Dynamic Response of the Carbon Dioxide-Concentrating Mechanism to Carbon Assimilation Behavior in Fremyella diplosiphon

open access: yesmBio, 2020
Cyanobacteria use a carbon dioxide (CO2)-concentrating mechanism (CCM) that enhances their carbon fixation efficiency and is regulated by many environmental factors that impact photosynthesis, including carbon availability, light levels, and nutrient ...

Papaya (Carica papaya L.) Leaf Area Estimation and Single-leaf Net Photosynthetic CO2 Assimilation Rate Following Leaf Defoliation and Fruit Thinning

open access: yesHortScience, 2020
Papaya (Carica papaya L.) leaves are large, up to 70 cm wide, and frequently deeply lobed, with seven to 13 major veins. The scan width of current handheld digital leaf area instruments is generally less than 15 cm.

Sun leaves up-regulate the photorespiratory pathway to maintain a high rate of CO2 assimilation in tobacco

open access: yesFrontiers in Plant Science, 2014
The greater rate of CO2 assimilation in sun-grown tobacco leaves leads to lower intercellular and chloroplast CO2 concentrations and, thus, a higher rate of oxygenation of ribulose-1,5-bisphosphate (RuBP) than in shade-grown leaves.

Analysis of CO2 Fluxes: Inclusion of Wall Conductance (Gw) on the Estimation of Rubisco Activity, Vcmax of Soybean Leaves

open access: yesHayati Journal of Biosciences, 2011
In global change research, where modelling of CO2 fluxes from plants is an important component in determining vegetation capacity to protect the climate, mechanistic-based modelling is needed when projection of future CO2 absorption dynamics need to be ...

Photorespiration plays an important role in the regulation of photosynthetic electron flow under fluctuating light in tobacco plants grown under full sunlight

open access: yesFrontiers in Plant Science, 2015
Plants usually experience dynamic fluctuations of light intensities under natural conditions. However, the responses of mesophyll conductance, CO2 assimilation, and photorespiration to light fluctuation are not well understood.

Leaf photosynthesis and yield components of mung bean under fully open-air elevated [CO2]

open access: yesJournal of Integrative Agriculture, 2015
Mung bean (Vigna radiata L.) has the potential to establish symbiosis with rhizobia, and symbiotic association of soil micro flora may facilitate the photosynthesis and plant growth response to elevated [CO2].
