Stomata, the small pores on the surfaces of leaves and stalks, regulate the flow of gases in and out of leaves and thus plants as a whole. They adapt to local and global changes on all timescales ...

Research from Los Alamos National Laboratory indicates that stress-free piñon might be able to better face drought.

Stomata resemble doughnuts -- a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells -- each known as a guard cell.

It's a hot, dry summer afternoon, and the skies offer no relief for a field of soybeans. But within those green leaves, these ...

Stomata development in plants unraveled Date: April 3, 2012 Source: VIB Summary: Researchers have unraveled the action mechanism of the main plant hormone that regulates the development of stomata ...

When temperatures are high, the stomata open to cool down. In dry conditions, they close to prevent water loss. So, when conditions are dry and hot, this may evoke conflicting—and therefore less ...

Introduction (written for students): Leaf stomata are the principal means of gas exchange in vascular plants. Stomata are small pores, typically on the undersides of leaves, that are opened or closed ...

Quantifying those changes will help scientists understand how quickly stomata can open and close, which ultimately determines the balance between how much carbon a plant absorbs and how much water ...

Stomata resemble doughnuts -- a circular pore with a hole in the middle for gas to enter or leave the plant. The pore consists of two cells -- each known as a guard cell.

The Plant Cell, Vol. 7, No. 12 (Dec., 1995), pp. 2227-2239 (13 pages) Stomata regulate gas exchange through the aerial plant epidermis by controlling the width of a pore bordered by two guard cells.

Leaf transpiration occurs through pores called stomata, and at a necessary "cost", displaces of much of its valuable water into the atmosphere.
