Stomatal conductance limited the CO2 response of grassland in the last century [PDF]
BMC Biology, 2021 Background The anthropogenic increase of atmospheric CO2 concentration (c a) is impacting carbon (C), water, and nitrogen (N) cycles in grassland and other terrestrial biomes.

Smaller, faster stomata: scaling of stomatal size, rate of response, and stomatal conductance [PDF]
Journal of Experimental Botany, 2013 Maximum and minimum stomatal conductance, as well as stomatal size and rate of response, are known to vary widely across plant species, but the functional relationship between these static and dynamic stomatal properties is unknown. The objective of this study was to test three hypotheses: (i) operating stomatal conductance under standard conditions (g

Hydraulic constraints to stomatal conductance in flooded trees. [PDF]
OecologiaAbstract Stomatal closure is a pervasive response among trees exposed to flooded soil. We tested whether this response is caused by reduced hydraulic conductance in the soil-to-leaf hydraulic continuum (k total), and particularly by reduced root hydraulic conductance (k root), which has been widely hypothesized.

Radiometric Method for Determining Canopy Stomatal Conductance in Controlled Environments [PDF]
Agronomy, 2019 Canopy stomatal conductance is a key physiological factor controlling transpiration from plant canopies, but it is extremely difficult to determine in field environments.

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 ...

Speed of light-induced stomatal movement is not correlated to initial or final stomatal conductance in rice. [PDF]
Photosynthetica, 2022 In nature, plants are often confronted with wide variations in light intensity, which may cause a massive carbon loss and water waste. Here, we investigated the response of photosynthetic rate and stomatal conductance to fluctuating light among ten rice genotypes and their influence on plant acclimation and intrinsic water-use efficiency (WUEi ...

Plant Science, 2014 During leaf development, the increase in stomatal conductance cannot meet photosynthetic demand for CO2, thus leading to stomatal limitation of photosynthesis (Ls). Considering the crucial influences of stomatal development on stomatal conductance, we speculated whether stomatal development limits photosynthesis to some extent. To test this hypothesis,

Stomatal conductance tracks soil-to-leaf hydraulic conductance in faba bean and maize during soil drying. [PDF]
Plant Physiol, 2022 Although regulation of stomatal conductance is widely assumed to be the most important plant response to soil drying, the picture is incomplete when hydraulic conductance from soil to the leaf, upstream of the stomata, is not considered.

Systemic Signaling in the Regulation of Stomatal Conductance [PDF]
Plant Physiology, 2020 Dear Editor, Plants use systemic signaling networks to spread information on locally perceived stimuli and coordinate responses in different plant parts. In natural environments, sun flecks and leaf-shading may lead to rapid and large changes in light conditions within the canopy and plants need ...

Geophysical Research Letters, 2022 The spatio‐temporal variation of stomatal conductance directly regulates photosynthesis, water partitioning, and biosphere‐atmosphere interactions. While many studies have focused on stomatal response to stresses, the spatial variation of unstressed ...
