Stomatal trait variation may have evolved more in response to pathogens than climate, or climate may be affecting the traits in unexpected ways.

Stomatal cell wall composition: distinct structural patterns in different phylogenetic groups
Stomata are pores regulating gas exchange in land plants. Stomatal morphology has remained largely consistent through ∼400 million years of plant evolution, though cell wall composition has changed. Shtein et al...

A fresh look at guard cell walls
Arguably, one of the best known ‘structure-function’ relationships in plant biology is the role played by cellulose microfibrils within the walls of the guard cells in stomatal opening. Stomata* are the controllable...
