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 ...

“Leaves have evolved over millions of years to optimize light collection, transport of nutrients to and from the plant body, and mechanical stability against natural stresses,” says David Young a ...

video: Professor Miltos Tsiantis from the Max Planck Institute for Plant Breeding Research in Cologne talks about his recent work in CELL showing how genes act to determine leaf shape. view more ...

An apple may not fall far from the tree, but for a leaf, it depends on its shape. Elm or apple leaves — oval and symmetrical, with few protruding lobes — fall quickly, making them likely to end up ...

In efforts to better understand how soybean plants capture and use light, researchers at the University of Illinois ...

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 ...

Scientists identify protein that controls leaf growth and shape. In autumn, it is not only the colours that catch the eye, but also the different sizes and shapes of leaves. But what makes leaves of ...

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 ...

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 ...

All leaves develop from tiny buds, which consist of only a few cells. The buds always look the same, no matter what kind of leaf they eventually form. Not only that, but very similar leaf shapes can ...
