A new leaf imaging system lets scientists watch plant stomata control water loss and carbon uptake in real time.

Plants like fairy duster, mesquite, and many others have very small leaves and fewer stomata in their leaves to minimize moisture loss. Brittlebush grow smaller leaves in the summer than in the winter ...

URBANA, Ill. — For centuries, scientists have known that plants "breathe" through microscopic pores on their leaves called stomata. These tiny valves are the gatekeepers that balance the intake of ...

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 ...

Life in places like California’s Death Valley pushes everything to its limit. Temperatures rise past 120 degrees Fahrenheit. The light is harsh, the soil is dry, and most plants wilt fast. Yet one low ...

Shrubs in the desert Southwest have increased their water use efficiency at some of the highest rates ever observed to cope with a decades-long megadrought. That’s the finding of a new study from ...
