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 ...

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 ...

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 ...

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 ...
