Cellular perspectives for improving mesophyll conductance. [PDF]
Plant J, 2020 SummaryAfter entering the leaf, CO2 faces an intricate pathway to the site of photosynthetic fixation embedded within the chloroplasts. The efficiency of CO2 flux is hindered by a number of structural and biochemical barriers which, together, define the ease of flow of the gas within the leaf, termed mesophyll conductance.

Expression of a CO2-permeable aquaporin enhances mesophyll conductance in the C4 species Setaria viridis [PDF]
eLife, 2021 A fundamental limitation of photosynthetic carbon fixation is the availability of CO2. In C4 plants, primary carboxylation occurs in mesophyll cytosol, and little is known about the role of CO2 diffusion in facilitating C4 photosynthesis.

The Kinetics of Mesophyll Conductance and Photorespiration During Light Induction [PDF]
PlantsMesophyll conductance to CO2 (gm) act as a significant limiting factor influencing the CO2 assimilation rate (AN) during photosynthetic induction. However, the effect of vapor pressure deficit (VPD) on gm kinetics during light induction is not well ...

Responses of leaf stomatal and mesophyll conductance to abiotic stress factors
Journal of Integrative Agriculture, 2022 Plant photosynthesis assimilates CO2 from the atmosphere, and CO2 diffusion efficiency is mainly constrained by stomatal and mesophyll resistance. The stomatal and mesophyll conductance of plants are sensitive to abiotic stress factors, which affect the ...

Analysis of mesophyll conductance in five understory herbaceous species. [PDF]
Physiol Mol Biol Plants, 2020 Mesophyll conductance (g m) has received over time much less attention than stomatal conductance (g s), although it affects leaf photosynthesis to about the same extent as stomatal conductance does. The objective of this study was to analyze the g m trend in five understory herbaceous species growing in a close-canopy forest in the north-west of Italy.

Interaction of Soil Texture and Irrigation Level Improves Mesophyll Conductance Estimation [PDF]
PlantsCombining leaf gas exchange with chlorophyll fluorescence, this study quantified the effects of soil water content (SWC) on mesophyll conductance (gm) and biochemical parameters in 8-year-old pear trees across three soil textures [clay (CS), sandy (SS ...

Exploring the potential of Δ17O in CO2 for determining mesophyll conductance. [PDF]
Plant Physiol, 2023 AbstractMesophyll conductance to CO2 from the intercellular air space to the CO2–H2O exchange site has been estimated using δ18O measurements (gm18). However, the gm18 estimates are affected by the uncertainties in the δ18O of leaf water where the CO2–H2O exchange takes place and the degree of equilibration between CO2 and H2O.

Leaf mesophyll conductance and leaf hydraulic conductance: an introduction to their measurement and coordination. [PDF]
Journal of Experimental Botany, 2013 Two highly contrasting variables summarizing the efficiency of transport of materials within the leaf are recognized as playing central roles in determining gas exchange and plant performance. This paper summarizes current approaches for the measurement of mesophyll conductance to CO2 (g m) and leaf hydraulic conductance (K leaf) and addresses the ...
