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

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."
