Researchers at the University of California San Diego made a significant breakthrough concerning how plants control their stomata ("mouths").
Collaboration includes researchers from Estonia and Finland.
Study funded by the U.S. National Science Foundation.
Importance of Stomata
Function
Stomata are small openings located on the underside of leaves.
They play a crucial role in the process of photosynthesis, allowing plants to take in carbon dioxide (CO2).
Stomata also enable the release of oxygen (O2), which is essential for the respiration of humans and other animals.
Mechanism
Guard cells flank each stomatal pore and regulate its opening and closing.
They open to allow CO2 intake but also risk losing water through evaporation when stomata are open.
Plants must balance CO2 intake with water vapor release to prevent dehydration.
Application of Discovery
Future Implications
Harnessing the newly discovered molecular pathway could lead to engineering plants better equipped to cope with increasing atmospheric CO2 levels due to climate change.
Enhancements may facilitate more efficient water usage alongside CO2 absorption, crucial for plant health and sustainability in changing climates.
