The past 40 years have witnessed extensive research on fractal structure and scale-free
dynamics in the brain. Although considerable progress has been made, a comprehensive …

Plants produce a rich diversity of biological forms, and the diversity of leaves is especially
notable. Mechanisms of leaf morphogenesis have been studied in the past two decades …

This monograph presents a general mathematical theory for biological growth. It provides
both a conceptual and a technical foundation for the understanding and analysis of …

Recent studies show that plant organ positioning may be mediated by localized
concentrations of the plant hormone auxin. Auxin patterning in the shoot apical meristem is …

The active transport of the plant hormone auxin plays a major role in the initiation of organs
at the shoot apex. Polar localized membrane proteins of the PIN1 family facilitate this …

Morphogenesis in living organisms relies on the integration of both biochemical and
mechanical signals. During the last decade, attention has been mainly focused on the role of …

The shape of an organism relies on a complex network of genetic regulations and on the
homeostasis and distribution of growth factors. In parallel to the molecular control of growth …

Plants are under tremendous mechanical forces generated by turgor pressure. How do
these forces mediate growth and development? In order to answer this question, it is …

Phyllotaxis, the regular arrangement of leaves and flowers around the stem, is a key feature
of plant architecture. Current models propose that the spatiotemporal regulation of organ …

Current theories and models of the formation of phyllotactic patterns at plant apical
meristems center on either transport of the growth hormone auxin or the mechanical …
