We've all heard the classic saying "leaves of three, let it be," which means don't touch the poison ivy. But just how accurate is that timeless phrase? While this specific mnemonic device exists to ...

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 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 ...

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 ...

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 ...

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 ...

The advent of deep learning has greatly expanded the frontiers of plant leaf image recognition and identification. Contemporary methodologies integrate convolutional neural networks with traditional ...

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 ...

Not all the trees in this guide are native to Ireland, but most are. Our island has a small suite of native trees compared with continental Europe. The meticulous classification of each species in 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 ...
