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 ...

Galapagos daisies evolved similar jagged leaves through different genes. This shows evolution can reach the same result in ...

“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 ...

That’s according to research published this week in Genes and Development. The article, which draws on work based out of the Max Planck Institute for Plant Breeding Research (MPIPZ), demonstrates 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 ...

Autumn is around the corner, and throughout the temperate latitudes of the northern hemisphere deciduous trees are preparing to shed their leaves. As the leaves flutter down, each one tells a story ...

Brassica crops, such as B. rapa, often display variations in leaf shape, including entire or lobed leaves, which significantly impact their adaptability and agricultural utility. Lobed leaves offer ...

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 ...

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 ...

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 ...
