Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata ...

Stomata are critical to plant biology and scientists have found a key to how they get there. Scientists studying plants have uncovered a key part of the process that forms one of the most important ...

Plant behavior may seem rather boring compared with the frenetic excesses of animals. Yet the lives of our vegetable friends, who tirelessly feed the entire biosphere (including us), are full of ...

Open (left) and closed (right) stomata found on the surface of plants' leaves, stems and other organs. Through the stomata, plants exchange oxygen and carbon dioxide, and lose more than 95 percent of ...

Daniel Urban & Corinne Campbell shows ciLiving host, Jaclyn Friedlander how to collect a simple stomata imprint from plants and view it under a microscope. This video shows how to collect a simple ...

Scientists have uncovered a unique mechanism that regulates the opening of stomata in plants. Phosphorylation of the amino acid Thr881 on the plasma membrane proton pump plays a key role in this ...

Stomata open in response to blue light, and close in the presence of abscisic acid (ABA), which is biosynthesized when the plant is under dark conditions and/or drought stress. Stomata are essential ...

Just as humans cannot breathe underwater, the tiny pores of plants can't exchange air underwater. Even worse, having pores under water promotes the entry of water, microbes and other undesirable ...

New research has shed light on when plants first evolved the ability to respond to changing humidity in the air around them, and was probably a feature of a common ancestor of both flowering plants ...
