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 ...

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 ...

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 ...

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 ...

These trees have one leaf attached to each stem. Leaves with a consistent leaf edge are called unlobed leaves while trees with leaves that form shapes along their margins are called lobed leaves. If ...

Environmentally induced heterophylly provides a useful model system for studying the developmental basis of differing leaf shapes. The semiaquatic Ranunculus flabellaris exhibits typical ...

Leaf lobes play a critical role in improving gas exchange, canopy architecture, and enabling high-density planting, which benefits Brassica crops in agricultural practices. Despite their importance, ...

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 ...
