Stomatal, mesophyll conductance, and biochemical limitations to photosynthesis during induction [PDF]
Plant Physiology, 2020 Abstract The dynamics of leaf photosynthesis in fluctuating light affects carbon gain by plants. Mesophyll conductance (gm) limits CO2 assimilation rate (A) under the steady state, but the extent of this limitation under non-steady-state conditions is unknown.

Frontiers in Plant Science, 2023 Carbon isotope composition (δ13C) has been widely used to estimate the intrinsic water-use efficiency (iWUE) of plants in ecosystems around the world, providing an ultimate record of the functional response of plants to climate change.

Cell wall composition strongly influences mesophyll conductance in gymnosperms [PDF]
The Plant Journal, 2020 SummaryCell wall thickness is widely recognized as one of the main determinants of mesophyll conductance to CO2 (gm). However, little is known about the components that regulate effective CO2 diffusivity in the cell wall (i.e. the ratio between actual porosity and tortuosity, the other two biophysical diffusion properties of cell walls).

Temperature response of carbon isotope discrimination and mesophyll conductance in tobacco [PDF]
Plant, Cell & Environment, 2012 ABSTRACTThe partial pressure of CO2 at the sites of carboxylation within chloroplasts depends on the conductance to CO2 diffusion from intercellular airspace to the sites of carboxylation, termed mesophyll conductance (gm). We investigated the temperature response of gm in tobacco (Nicotiana tabacum) by combining gas exchange in high light, ambient CO2

A microscale model for combined CO(2) diffusion and photosynthesis in leaves. [PDF]
PLoS ONE, 2012 Transport of CO(2) in leaves was investigated by combining a 2-D, microscale CO(2) transport model with photosynthesis kinetics in wheat (Triticum aestivum L.) leaves.

Mesophyll conductance in land surface models: effects on photosynthesis and transpiration [PDF]
The Plant Journal, 2019 SummaryThe CO2transfer conductance within plant leaves (mesophyll conductance,gm) is currently not considered explicitly in most land surface models (LSMs), but instead treated implicitly as an intrinsic property of the photosynthetic machinery. Here, we review approaches to overcome this model deficiency by explicitly accounting forgm, which comprises

Variable mesophyll conductance revisited: theoretical background and experimental implications [PDF]
Plant, Cell & Environment, 2012 ABSTRACTThe CO2 concentration at the site of carboxylation inside the chloroplast stroma depends not only on the stomatal conductance, but also on the conductance of CO2 between substomatal cavities and the site of CO2 fixation. This conductance, commonly termed mesophyll conductance (gm), significantly constrains the rate of photosynthesis.

The Response Mechanism and Threshold of Spring Wheat to Rapid Drought
Atmosphere, 2022 In order to deeply understand the effect mechanism of rapid drought stress on the physiological and biochemical properties of crop leaves and determine drought thresholds, the potted spring wheat under two water treatments, adequate water supply and ...
