Abstract

Phyllotaxis refers to the spatial arrangement of leaves and flowers on a stem. A recent study by Zhang et al. described the developmental process underlying phyllotaxis establishment in the capitulum of Gerbera hybrida. This work represents a cornerstone for studying the development and diversification mechanisms of capitula in the Asteraceae.

Keywords: Asteraceae; Fibonacci numbers; Gerbera hybrida; auxin maxima; capitulum development; phyllotaxis.
