In botany, phyllotaxis (from Ancient Greek φύλλον (phúllon) ' leaf ' and τάξις (táxis) ' arrangement ') [1] or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature.

L’auxine occupe notamment le devant de la scène, avec la caractérisation récente de mutants pour des transporteurs d’auxine présentant une absence de feuille, mais on entrevoit d’ores et déjà des rôles pour d’autres effecteurs hormonaux, par exemple les cytokinines, depuis la caractérisation du mutant Abnormal Phyllotaxis par ...

Sep 11, 2017 · In this Primer I will give a broad overview of phyllotaxis, its emergence from the shoot apical meristem, how auxin and its transporter function as a ‘pattern generator’, and the role of tissue mechanics and computational modeling.

Feb 7, 2021 · In this review, I first summarize the classical knowledge of phyllotaxis from a morphological perspective. I then discuss recent advances in the regulation of phyllotaxis, from a molecular genetics perspective.

Phyllotaxis, the regular arrangement of leaves or flowers around a plant stem, is an example of developmental pattern formation and organogenesis. Phyllotaxis is characterized by the divergence angles between the organs, the most common angle being 137.5°, the golden angle.

The spiral arrangement of organs on plant stems, called spiral phyllotaxis, is a striking example of phenotypic bias in development. A vast majority of these spiral patterns tend to

Jan 15, 2013 · Plant architecture is characterised by the regular spacing of lateral organs along stems and branches, an arrangement known as phyllotaxis (derived from the ancient Greek words phyllon meaning ‘leaf’ and táxis meaning ‘arrangement’). Different types of phyllotaxis exist.

The precise arrangement of plant organs, also called phyllotaxis, has fascinated scientists from multiple disciplines. Whereas early work focused on morphological observations of phyllotaxis, recent findings have started to reveal the mechanisms behind this process, showing how molecular regulation and biochemical gradients interact with ...

Jul 12, 2011 · When two evenly spread organs are formed on a node, the phyllotaxis is decussate, and whorled when three or more organs arise simultaneously. Although phyllotactic patterns tend to be stable, they are affected by environmental factors and may change during the development of the plant.
