The Zamiaceae are often considered 'living fossils', but a close study of how they have evolved over millions of years can give a glimpse into the lives of past plants.

Stomatal traits do not determine species range via abiotic stress tolerance in Pooideae
Stomatal trait variation may have evolved more in response to pathogens than climate, or climate may be affecting the traits in unexpected ways.

Short- and long-term responses to elevated carbon dioxide use the same genetic controls
Manipulating stomatal traits could produce more crops for dry regions.
Stomatal anatomy coordinates leaf size with Rubisco kinetics in Limonium
Stomatal anatomy integrates Rubisco kinetics and leaf size in Limonium species, consistent with selection on functional coordination and shared developmental pathways.

StomaToy — Learning Plant Defence Through Play
Stomata are necessary for photosynthesis, but they're also access points for pathogens. How do plants defend them?

Savanna tree and C4 grass acclimation responses across low-to-high CO2
By the year 2100, atmospheric CO2 concentration ([CO2]a) could reach 800 ppm, having risen from ~200 ppm since the Neogene, beginning ~24 Myr ago. Changing [CO2]a affects plant carbon–water balance, with implications...

BLINKing stomata: an optogenetic approach to improve plant growth and water use
Photosynthesis needs water. Guest blogger Maria Papanatsiou has a new way of increasing water efficiency in plants, enabling them to do more with less.

Ecophysiology of early lineage vascular plants
Tropical understory communities are highly diverse, and plants in these environments must optimize functional traits to ensure ecological and evolutionary success. Campany et al. survey the ecophysiology of two spore...
Hornwort stomata walls are not built for movement
Guard cell walls are built to resist bending and deformation to open and close the pore. Pectins provide flexibility and resilience to walls; in particular arabinans and unesterified homo-galacturonans are required for...
Night-time transpiration facilitates respiratory carbon dioxide release
Night-time transpiration accounts for a considerable amount of water loss in crop plants, yet its biological function, regulation and response to salt stress are poorly understood. Even et al. present data on barley...
Stomatal conductance and elevated CO2
Studies have indicated that plant stomatal conductance (gs) decreases in response to elevated atmospheric CO2, a phenomenon of significance for the global hydrological cycle. However, gs increases across certain CO2...

Hooray for the hydathode!
There's more than one way for a pathogen to gain access to healthy leaf.

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...
Guard cells first, then epidermis
Stomata in the moss Funaria are regularly spaced at the base of the capsule. Merced and Renzaglia describe the patterning and distribution of stomata and how they are coordinated with the formation of substomatal...
