Two-step mechanism of spiral phyllotaxis.

The unified rule of phyllotaxis explaining both spiral and non-spiral arrangements

A unified rule of phyllotaxis is proposed to explain both types of arrangement: the developed leaves form vertical rows along the stem, so that the number of leaf rows is kept constant irrespective of stem growth.

A hierarchically patterned, bioinspired e-skin able to detect the direction of applied pressure for robotics

A biomimetic soft electronic skin that is composed of an array of capacitors and capable of measuring and discriminating in real time both normal and tangential forces is reported, enabled by a three-dimensional structure that mimics the interlocked dermis-epidermis interface in human skin.

The riddle of phyllotaxis: exquisite control of divergence angle

It is emphasized that accurate control of apical divergence angle is at the heart of the numerical riddle of spiral phyllotaxis.

Vascular phyllotaxis transition and an evolutionary mechanism of phyllotaxis

It is shown that continuous changes of the trace length induce transitions between the fractional or- ders in the vascular structure, which suggests an evolutionary mechanism for the phenomenon of phyllotaxis.

On the relationship between phyllotaxy and vasculature: a synthesis

There is a definite relationship between the phyllotactic fraction and the sympodia uniting median leaf traces in a stem and these controls most likely operate on factors that influence the formation of orthostichies such as the relationship between leaf-shape and size of the apical dome.

Pattern Specification and Realization in Photomorphogenesis

Development in multicellular organisms is usually discussed from the point of view of growth, differentiation, and morphogenesis. “Growth” refers to quantitative changes; “differentiation” refers to

Experiments on Phyllotaxis. I. The Effect of Isolating a Primordium

Theories concerning the causes of phyllotaxis may be divided conveniently into two groups: that of SCHIMPER and BRAUN, who suggested that spiral sequences were due to a spiral growth impulse which travelled up the stem, the leaves arising at regular intervals along the course of this spiral.

PHYLLOTAXIS IN THE DICOTYLEDON FROM THE STANDPOINT OF DEVELOPMENTAL ANATOMY

The problems of phyllotaxis are re‐examined from the standpoint of the initial adjustment of the units of shoot growth and it is pointed out that such primordia, once formed, are competing centres of activity and consequently tend to arise as nearly as possible opposite to one another, as exemplified by the simplest case of alternate or 1/2 phyllOTaxis.
