Explaining the shape of a leaf with the help of systems biology

Which factors determine the shape of a leaf? By using different methods of systems biology, Barbara Terebieniec has identified genes that control the leaf shape of the European aspen. Barbara Terebieniec presented her doctoral ...

New leaf shapes for thale cress

Anyone who looks at their bowl of salad or at their garden can see how different the shapes of leaves can be. Spinach leaves, for example, have smooth edges and are comparatively simple in form, while parsley leaves are deeply ...

New paper on the phylogeny of the Brassicaceae

The mustard family Brassicaceae (also known as Crucifers, from the cross-like form of their flowers) comprises ca. 4000 species, including economically important crops such as cabbage and canola, many species adapted to extreme ...

Scientists discover how mechanical strain shapes plants

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and Carnegie Mellon University in the U.S. have discovered how mechanical forces can influence the shapes of plant leaves and flower petals.

Scientists identify protein that controls leaf growth and shape

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 Max Planck Institute ...

Researchers crack genetic code determining leaf shape in cotton

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 varieties that make the most ...

A small piece of DNA with a large effect on leaf shape

Millions of years ago, some plants in the mustard family made the switch from simple leaves to complex leaves through two tiny tweaks to a single gene. One tweak to a small enhancer sequence gave the gene a new domain of ...
