PANAMA CITY, Panama, July 29 (UPI) --The evolutionary pressures of hunger, reproduction and pollination have driven a unique relationship between butterflies and plants. To encourage the faithfulness ...

Plant biologists at ITbM, Nagoya University 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, ...

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 ...

Different plants exhibit leaves with very diverse shapes, and scientists studying a carnivorous plant called Utricularia gibba (bladderwort) have learned how nature creates all the various leaf forms ...

Mix and match for interest and variety. Look around you today, and you’ll see leaves in an entirely new light.

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 ...
