Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism - tiny pores known as ...

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 ...

Researchers have discovered two genes that guide land plants to develop microscopic pores that they can open and close as if each pore was a tiny mouth. Plants wouldn't have been able to move from ...

We are increasingly confronted with the impacts of climate change, with failed harvests being only one example. Addressing these challenges requires multifaceted approaches, including making plants ...

correlation and causation: Many students do not understand the fundamental difference between correlation and causation. In this lab, stomata density variation likely results from interacting ...

I always assumed Clark Moorten watered the cactus at night because the Botanical Garden was closed. But now I'm thinking he had another big reason to set up his sprinkler on the agave and cactus to ...

Scientists discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism -- tiny pores known as 'stomata' ...

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 ...

Scientists with two disparate sets of expertise -- in plant biology and protein structural chemistry -- have unraveled the atomic basis of how optimal numbers of stomata are made in leaves. Plants ...
