Mesophyll conductance limitation of photosynthesis in poplar under elevated ozone
Science of The Total Environment, 2019Finite mesophyll conductance (gm) reduces the rate of CO2 diffusion from the leaf intercellular space to the chloroplast and constitutes a major limitation of photosynthesis in trees. While it is well established that gm is decreased by stressors such as drought and high temperature, few studies have investigated if the phytotoxic air pollutant ozone ...

Estimation of Mesophyll Conductance and Its Applications
2016CO2 travels from the atmosphere through stomata to the carboxylation sites where CO2 is fixed (Figure 4.1). During this diffusional process, CO2 travels through the leaf boundary layer, stomata, mesophyll cell wall, mesophyll plasmalemma, and cytosol and chloroplast membranes. Carbonic anhydrase catalyzes the reversible hydration of CO2 to HCO3

[Mesophyll conductance to CO2: Methods and current knowledge].
Ying yong sheng tai xue bao = The journal of applied ecology, 2021Mesophyll conductance (gm), the total conductance of CO2 diffusion from substomatal cavity to the site of carboxylation within chloroplast, is a major limiting factor for photosynthesis and a key parameter for improving photosynthetic resource use efficiency of crops.

SUMMARYDrought stress significantly affects cotton's net photosynthetic rate (A) by restraining stomatal (gs) and mesophyll conductance (gm) as well as perturbing its biochemical process, resulting in yield reductions. Despite the significant progress in dissecting effects of drought on photosynthesis, the variability observed in cotton's gm, and the ...

Leaf hydraulic conductance and mesophyll conductance are not closely related within a single species
Plant, Cell & Environment, 2016AbstractStomata represent one resistor in a series of resistances for carbon and water exchange between the leaf and the atmosphere; the remaining resistors occurring within the leaf, commonly represented as mesophyll conductance to CO2, gm, and leaf hydraulic conductance, kLeaf.

The temperature response of mesophyll conductance to CO2 diffusion (gm) has been shown to vary considerably between species but remains poorly understood. Here, we tested the hypothesis that increases in chloroplast surface area with increasing temperature, due to the formation of chloroplast protrusions, caused observed positive responses of gm to ...

The response of mesophyll conductance to short‐term CO2 variation is related to stomatal conductance
Plant, Cell & EnvironmentAbstractThe response of mesophyll conductance (gm) to CO2 plays a key role in photosynthesis and ecosystem carbon cycles under climate change. Despite numerous studies, there is still debate about how gm responds to short‐term CO2 variations. Here we used multiple methods and looked at the relationship between stomatal conductance to CO2 (gsc) and gm ...
