Excited to share our latest research on stomatal dynamics! We developed a microscope to image individual stomata. Maize stomata respond faster to light changes, optimizing CO₂ uptake, while chrysanthemum shows slower closure, affecting water use. onlinelibrary.wiley.com/doi/epdf/10.... #Stomata

Happy to share our preprint on negative relationship between adaxial stomatal density and yield in wheat under field conditions, especially under water and nutrient limitation.
Higher adaxial stomatal density is associated with lower grain yield in spring wheat https://www.biorxiv.org/content/10.1101/2025.01.07.631641v1
