Plants shape their organs with a precision demanded by optimal function; organ shaping
requires control over cell wall expansion anisotropy. Focusing on multicellular organs, I …

Experimental evidence on the role of the cell cycle in plant growth regulation does not
exclusively fit the cellular (division drives growth) or the organismal perspective (division …

Morphogenesis emerges from complex multiscale interactions between genetic and
mechanical processes. To understand these processes, the evolution of cell shape …

In 1859 Darwin described a deceptively simple mechanism that he called" natural selection,"
a combination of variation, inheritance, and reproductive success. He argued that this …

The rapid closure of the Venus flytrap (Dionaea muscipula) leaf in about 100 ms is one of
the fastest movements in the plant kingdom. This led Darwin to describe the plant as “one of …

Morphogenesis emerges from complex multiscale interactions between genetic and
mechanical processes. To understand these processes, the evolution of cell shape …

The presence of diffuse morphogen gradients in tissues supports a view in which growth is
locally homogenous. Here we challenge this view: we used a high-resolution quantitative …

Although curvature of biological surfaces has been considered from mathematical and
biophysical perspectives, its molecular and developmental basis is unclear. We have …

A key challenge in biology is to understand how the regional control of cell growth gives rise
to final organ forms. Plant leaves must coordinate growth along both the proximodistal and …

Cell size and growth kinetics are fundamental cellular properties with important
physiological implications. Classical studies on yeast, and recently on bacteria, have …
