Steroids control gas exchange in plants
Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the ...

Chemical signal helps plants control their “breathing”
For most plants, staying alive means adapting quickly to a constantly changing environment. In a drought, staving off water loss is vital. On a sunny day, absorbing carbon dioxide to generate energy through ...

A new transporter gene that regulates plant transpiration
When plants feel stress from a lack of water, they close their epidermal pores, or stomata, to prevent water loss via transpiration. Each stoma is flanked by a pair of guard cells, which change shape to close or open stomata ...

How plants space out the pores through which they breathe
The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth, according to John Innes Centre scientists.

Araucarias gauge ancient levels of carbon dioxide
One way of telling how much carbon dioxide was in the atmosphere in the past is by counting pores (or stomata) in leaves – the tiny openings plants use to absorb CO2 and lose water. It may seem far-f ...

Rising CO2 is causing plants to release less water to the atmosphere, researchers say
As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the ...
