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 ...

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 ...

In autumn, it is not only the colours that catch the eye, but also the different sizes and shapes of leaves. But what makes leaves of different plants differ so much in their shapes? Scientists at the ...

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 ...

Leaf morphogenesis is the process by which a flat, determinate organ emerges from the shoot apical meristem and acquires its species-specific form. This involves a tightly coordinated sequence of ...
