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 (a) could reach 800 ppm, having risen from ~200 ppm since the Neogene, beginning ~24 Myr ago....

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....

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...

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...

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....

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...

When fungal infection comes to Pinus radiata, it can run through the bottom of the crown of the tree, removing its leaves....

How do you get more DNA down a pollen tube?

A common event for flowering plants is whole genome duplication (WGD), where a plant gets extra chromosomes. It’s often studied in mature...

Simulating the effects of local adaptation and life history on the ability of plants to track climate shifts

Local adaptation is common but not universal in plants and results from the interplay of gene flow with natural selection. Gene flow...

What creates Gentiana diversity in mountains?

The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et...
