Abscisic acid (ABA) prevents opening of closed stomata and causes open stomata to close. A dual-source model is proposed linking ABA to diurnal stomatal movements. Darkness would favour guard cell ...

New research is set to change the textbook understanding of how plants breathe. Researchers have developed the first full 3D model of a guard cell. New research is set to change the textbook ...

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 (left, left ...

The structure of the mature stomatal complex of Flagellaria indica L. was studied since the Flagellariaceae is reported to be one of a handful of nongrass families with a grass_type stoma, and since ...

Plants face a dilemma in dry conditions: they have to seal themselves off to prevent losing too much water but this also limits their uptake of carbon dioxide. A sensory network assures that the plant ...

With intensifying global warming and climate change, drought has become a major threat to global agriculture, impacting crop yields and food security. To survive such adverse events, plants have ...
