CO2 mesophyll conductance regulated by light: a review
Planta, 2023Light quality and intensity regulate plant mesophyll conductance, which has played an essential role in photosynthesis by controlling leaf structural and biochemical properties. Mesophyll conductance (gm), a crucial physiological factor influencing the photosynthetic rate of leaves, is used to describe the resistance of CO2 from the sub-stomatal cavity

Mesophyll conductance in gymnosperms
2020Mesophyll conductance is the CO2 diffusion efficiency through the leaf from the substomatal cavity to chloroplasts located in plant cells. It is an important step determining photosynthetic efficiency next to photosynthetic biochemistry and stomatal conductance. Mesophyll conductance limits photosynthesis and therefore plant growth.

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 ...
