“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 ...

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 ...

The tropical butterfly Heliconius erato distinguishes between shapes, and uses them as a cue for choosing the plants on which to feed and lay eggs, shows new research by scientists from the University ...

Applied mathematicians dissected the morphology of the plantain lily, a characteristic long leaf with a saddle-like arc midsection and closely packed ripples along the edges. The simple cause of the ...

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 ...

Plant biologists have discovered the key element, an EPFL2 peptide that is responsible for creating the teeth-like shapes on plant leaves. The zigzag edges of leaves, so-called leaf teeth, are ...

This is something I only noticed when I picked this picture for the article and had time to look at it carefully as I wrote ...

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 ...

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 ...

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 ...
