Plants constantly make trade-offs in their decisions: more light means more opportunity for photosynthesis, but then hot temperatures and dry air makes wilting more likely. Stomata - microscopic ...

A newly-discovered mechanism is responsible for the closing of stomata in leaves to prevent water loss and also controls the development of lateral roots to better deal with abiotic stresses.

Plants obtain the water they need from the ground through their root systems. From there it travels to leaves, flowers, and fruits through a system of tubes. These tubes are called xylem. From the ...

Have you ever wondered just how much water plants need to grow, or indeed why they need it? Plants lose a lot of water when they take in carbon dioxide from the atmosphere, so they need up to 300 ...

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 ...
