#Stomata, which are the pores on the leaf surface which regulate CO2 coming into the leaf, but also the amount of water vapour lost (transpiration), react relatively slowly to environmental changes. One of my PhD students just got his first paper out, showing for beech that shade adapted leaves are more responsive to changes in light. This has consequences for shaded leaves in the canopy of forest : more responsive stomata have a more efficient CO2 uptake and thus #Photosynthesis. Plants under drought were also more responsive, reducing their amount of water lost by transpiration and increasing thereby their #WaterUseEfficiency.

The latest research results on stomatal dynamics from our PhD candidate (and quite proud of it :-) : the shade tolerant Fagus sylvatica , the common beech, shows more reactive stomatal responses on shade leaves than on sun leaves, suggesting an optimisation to increase CO2 uptake. The differences in stomatal dynamics were not related, as usually assumed, to differences in stomatal morphology.

Are smaller stomata faster in reacting to environmental changes such as light, CO2, atmospheric humidity, temperature ? I have participated with our data in a group publication where we take a closer look at the "Speedy small stomata" paradigm.
Using data from over 80 plant species, we found only weak correlations between stomatal size and maximum stomatal closing or opening speeds as well as response times.
Instead, stomatal speed appears to be context-dependent, shaped by species-specific traits, stomatal type and broader anatomical and physiological features.
These findings support a trait-based approach to assessing stomatal kinetics, which has implications for understanding #EcosystemFunctioning under #ClimateChange and #CropBreeding for higher #WaterUseEfficiency and #photosynthesis.Woning et al. Revisiting the relationship between stomatal size and speed across species – a meta-analysis

I'm quite satisfied with this large collaboration paper coming out just before 2026, challenging a paradigm : small stomata are not necessarily reacting more rapidly to changes in light.

"So next time you look upon a leaf, consider the frantic pace of dynamic calculation and adjustment of millions of little mouths, reacting as your breath falls upon them. Realise that our own fate, tied to the performance of forests and crops in future climates, hangs on the behaviour of the stomata of different species. A good reason for us to understand these unassuming little valves."

In our new paper we question the conventional understanding that #diffusional limitations of CO2 contribute to the reduction in #photosynthesis at high #temperatures. We suggest that #stomata and #mesophyll membranes could work strategically to facilitate #transpiration cooling and #CO2 supply, thus alleviating #heat #stress on leaf photosynthetic function, albeit at the cost of reduced #WateUseEfficiency.

Volatile organic compounds (#VOCs) emitted by injured plants increase the cytosolic Ca2+ concentration in non-injured #Arabidopsis #leaves indicating that volatiles trigger the expression of biotic and abiotic #stress-responsive genes in a Ca2+-dependent manner. Tissue-specific high-resolution Ca2+ imaging shows that VOCs are rapidly taken up by the inner tissues via #stomata, leading to cytosolic Ca2+ increases and subsequent #defense responses in Arabidopsis leaves.

#Grasses have "respiratory pores" (called #stomata) that open and close to regulate the uptake of carbon dioxide (#CO2) for #photosynthesis on the one hand and water loss through transpiration on the other. Unlike many other plants, stomata in grasses form lateral "helper cells".

In particular, we are interested why the unique #morphology of grass stomata makes them so much more efficient in terms of gas exchange #physiology. Follow me if you like #nerd posts about #plantsci
