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 ...

In a second experiment, Dell'Aglio et al. show that Heliconius erato prefer to lay eggs on leaves with a familiar shape, and tend to avoid laying on leaves with a shape that they have not previously ...

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 ...

PANAMA CITY, Panama, July 29 (UPI) --The evolutionary pressures of hunger, reproduction and pollination have driven a unique relationship between butterflies and plants. To encourage the faithfulness ...

Subtle changes in genetics can have major effects on how leaves grow into a wide variety of shapes. John Innes Centre Around the globe, plants have evolved to use their leaves for many purposes: broad ...

Miltos Tsiantis and his group from the Max Planck Institute for Plant Breeding Research want to find out how biological forms develop and the basis for their diversity. The researchers are using thale ...

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 ...

It's a Treehugger's dream come true. Leafsnap is a free app that identifies plant species of all kinds, from flowers and bark to fruit and trees. Go for a walk, take a shot of a leaf, and this little ...

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 ...

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 ...
