How nitrate overcomes plant hormone inhibition to boost seed germination
Abscisic acid (ABA), a key environmental response hormone, strongly inhibits seed germination and serves as a central ...

Research discovers plants utilize drought stress hormone to block snacking spider mites
When there is a water shortage, plants act to conserve water by producing the drought stress hormone ABA to close their stomata. Coincidentally, the closure of stomata also obstructs the preferred ...

Plant Vacuoles and the Regulation of Stomatal Opening
How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled ...

Schematic Illustration of the Regulating Processes at the Guard Cells (IMAGE)
Caption Involvement of the ABA receptors in ABA- and CO2-induced closure of the stoma. When in drought stress mode, the plant produces large amounts of the ABA hormone that acts on the guard cells ...

Plants 'breathe' with millions of tiny mouths—lasers illuminate evolution of stomata behavior
One such behavior is the dynamic opening and closing of millions of tiny mouths (called stomata) located on each leaf, through which plants "breathe." In this process they let out water extracted ...

Proposed Signaling Pathway of Stomata Opening in Response to Blue Light (IMAGE)
1) Phototropin receptors in the guard cells of stomata receives blue light; 2) Signal transmission by BLUS1, BHP and PP1 (proposed signaling components); 3) Activation of the plasma membrane ...

Coming closer to a stoma ion channel
Stomata are like windows on the surface of leaves: they close to prevent water vapour loss during transpiration, but open to allow CO 2 uptake for photosynthesis. The stomatal pore aperture ...
