研究人员针对不同谱系植物（褐藻Fucales、苔藓bryophytes、石松lycophytes和真蕨monilophytes）中叶序（phyllotaxis）模式的趋同演化问题，通过抑制模型（inhibition model）揭示了从褐藻到被子植物中primordia（原基）排列的普适物理化学机制，发现Fibonacci螺旋（斐波那契螺旋 ...

The vortex is ubiquitous in nature, spanning from the galaxy, ocean flow, to phyllotaxis. In electromagnetic wave, the vortex can be found in spiral wavefront profiles, representing the orbital ...

Next time you go outside, take a minute to look at your local leaf arrangements. You’ll probably notice a few different patterns. In basil plants, each leaf is about 90 degrees — a quarter-turn — from ...

This is a preview. Log in through your library . Abstract Using the plant model Arabidopsis, the relationship between day length, the size of the shoot apical meristem, and the robustness of ...

Leaf arrangement with one leaf per node is called alternate phyllotaxis whereas arrangement with two or more leaves per node is called whorled phyllotaxis. Common alternate types are distichous ...
