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.

🌞 Together, these results point to light as the key environmental cue shaping stomatal patterning, helping refine how we understand leaf development and plant responses to changing environments. (8/8)

Carbon dioxide or photosynthetically active radiation? Evaluation of the significance of individual environmental factors that control leaf stomatal development

AbstractBackground and Aims. Stomata are pores in the plant epidermis that regulate gas exchange by controlling CO2 uptake and water loss through transpira

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.
