Leaf size and venation show remarkable diversity across dicotyledons, and are key determinants of plant adaptation in ecosystems past and present. Here we present global scaling relationships of ...

Plant leaves need a large surface area to capture sunlight for photosynthesis. Dr. Emanuele Scacchi and Professor Marja Timmermans from the Center for Plant Molecular Biology at the University of ...

The spiky, iconic Canadian maple leaf. A large, lush Florida palm leaf. Thin aspen leaves rustling in the crisp Colorado air. You can probably recall many different leaf shapes from many different ...

Spring arrives with a burst of life, but it also comes with a puzzle: those curling leaves on plants that make them look like they’re auditioning for a sculpture contest. While the shapes can seem ...

A doctoral student has identified a long-overlooked pattern in how plants evolved their equivalent of lungs -- tiny pores on the surfaces of leaves called stomata. Using specialized imaging techniques ...

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 ...

Most leaves are green due to the pigment chlorophyll, but other colours, such as oranges, reds and blues, may also be present due to less efficient photosynthetic pigments like anthocyanins, carotenes ...

This flower-like image shows a plant that is not developing quite right. It comes from a study in which scientists at EMBL and the University of Sydney unearthed the molecular feedback loop that ...
