We can find all kinds of leaves on our planet. Just think of tiny pine needles, fern fronds, ivy vines or a big banana leaf. My friend Eric Roalson is a professor at Washington State University who is ...

Scientists have determined how key developmental genes influence growth of cells to produce such differences in leaf form. The researchers were able to make thale cress, which typically produces ...

Two physicists from the Technical University of Denmark have found that leaf shape is a determining factor in the distance leaves travel as they fall from their tree. In their paper published in the ...

Researchers know that the variation in leaf shapes can mean big differences in a farmer's bottom line. Now, a new discovery gives plant breeders key genetic information they need to develop crop ...

The technique could be used on everything from flowers to cells to examine the factors that influence the shapes of plant parts. The story of a plant is etched in its leaves. A tree growing in a cold ...

Poison ivy can often be identified by its ‘mitten-shaped’ leaflets (pictured here) although its leaf shape can vary widely. Can you find the other poison ivy leaves in the picture? Poison ivy can ...

Watery adaptation: The structure and shape of lotus leaves growing on water (left) and above it (right) is influenced by mechanical forces. (Courtesy: F Xu/Fudan University) When the leaves of the ...

The story of a plant is etched in its leaves. A tree growing in a cold environment with plenty of water is more likely to have large leaves with many serrated teeth around the edges. But if the same ...
