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 ...

Applied mathematicians dissected the morphology of the plantain lily, a characteristic long leaf with a saddle-like arc midsection and closely packed ripples along the edges. The simple cause of the ...

IV.—Special Types in Special Environments FROM the previous papers it will be clear that degree of subordination to the stem accounts in large measure for the exteht to which leaves vary from the ...

A study suggests how mechanical forces influence the shapes of plant leaves and flower petals. The genetic and biomolecular mechanisms that give rise to complex 3D shapes in plant organs have been ...

Variation in the size and shape (physiognomy) of leaves has long been correlated to climate, and paleobotanists have used these correlations to reconstruct paleoclimate. Most studies focus on ...

In late summer, the world is rich with lush green foliage. Take a stroll through a park or some nearby woods after a rainstorm, and you'll find an abundance of leaves strewn on the ground. Pick one up ...

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 ...
