Blue Light Regulation of Stomatal Opening and the Plasma Membrane H+-ATPase | Plant
Physiology | Oxford Academic Skip to Main Content Advertisement Oxford Academic Journals …

Stomatal pores, each surrounded by a pair of guard cells, regulate CO2 uptake and water
loss from leaves. Stomatal opening is driven by the accumulation of K+ salts and sugars in …

Phototropins are blue-light receptors controlling a range of responses that serve to optimize
the photosynthetic efficiency of plants. These include phototropism, light-induced stomatal …

▪ Abstract Plants utilize several families of photoreceptors to fine-tune growth and
development over a large range of environmental conditions. The UV-A/blue light sensing …

Stomata are an attractive experimental system in plant biology, because the responses of
guard cells to environmental signals can be directly linked to changes in the aperture of …

Signaling photoreceptors use the information contained in the absorption of a photon to
modulate biological activity in plants and a wide range of organisms. The fundamental—and …

Stomata can be regarded as hydraulically driven valves in the leaf surface, which open to
allow CO2 uptake and close to prevent excessive loss of water. Movement of these …

14-3-3 proteins exert an extraordinarily widespread influence on cellular processes in all
eukaryotes. They operate by binding to specific phosphorylated sites on diverse target …

We isolated a total of 3× 108 guard cell protoplasts from 22,000 Arabidopsis thaliana plants
and identified 1734 unique proteins using three complementary proteomic methods: protein …

Phototropins are autophosphorylating protein kinases of plant-specific blue light receptors.
They regulate various blue light responses, including phototropism, chloroplast movements …
