Abstract:The veins of plant leaves exhibit a large variety of morphologies. They are often thought to result from their growth in a concentration scalar field. It is shown here that the topology of these patterns rather corresponds to what is expected from growth in a tensorial stress field. This is demonstrated by analogic experiments performed on crack formation in gel films where many characteristic venation patterns, of both dicotyledons and monocotyledons, were reproduced. This suggests… Expand

The Role of Elastic Stresses on Leaf Venation Morphogenesis
It is argued that the agreement between actual and simulated patterns provides strong evidence for the role of mechanical effects on venation development. Expand

Hierarchy optimization model is proposed for reinforcement distribution of plant venation, where energy criterion, shear stress and areoles division is responsible for three ranks of veins respectively. Expand
Morphogenetic processes: from leaves to embryos
The present manuscript is devoted to two works related to the spontaneous formation of patterns in Nature: venation in leaves and evolution of embryos. Morphogenetic processes and growth-inducedExpand
Petal shapes of sympetalous flowers: the interplay between growth, geometry and elasticity
The growth of a thin elastic sheet imposes constraints on its geometry such as its Gaussian curvature KG. In this paper, we construct the shapes of sympetalous bell-shaped flowers with a constantExpand
In silico leaf venation networks: growth and reorganization driven by mechanical forces.
The results suggest that the local structure of venation networks results from a reorganization driven by mechanical forces, independently of how veins form, supported by recent observations of vein development in young leaves and by the good quantitative agreement between simulations and data from mature leaves.

The consequences of the hypothesis that auxin is produced at a constant rate in every cell are determined and the model further implies the Sachs Canalization Hypothesis and resolves a dilemma regarding the role of auxin in cell growth. Expand
Modeling and visualization of leaf venation patterns
We introduce a class of biologically-motivated algorithms for generating leaf venation patterns. These algorithms simulate the interplay between three processes: (1) development of veins towardsExpand
Modeling and visualization of leaf venation patterns
A class of biologically-motivated algorithms for generating leaf venation patterns that simulate the interplay between three processes, including development of veins towards hormone (auxin) sources embedded in the leaf blade, and modification of both the vein pattern and source distribution by leaf growth.

A mathematical model based on the positive feedback regulation between plant hormone auxin and its efflux carrier can produce diverse leaf venation patterns with spatial regularity under similar conditions to those of leaf development, that is, in the presence of leaf expansion and auxin sink.

The Mechanics of Leaf Growth on Large Scales
Leaf growth is a process during which the leaf expands by many orders of magnitude, while maintaining a proper shape. Complex mechanisms which are not fully understood regulate the local, individualExpand
