## Summary Evidence is provided that ethylene is a positive regulator of hair cell development in the root epidermis of __Arabidopsis thaliana__. Treatment of seedlings with increasing concentrations of the ethylene precursor, 1βaminocyclopropaneβ1βcarboxylic acid (ACC) results in progressively mor
The root epidermis of Arabidopsis thaliana is formed by alternate "les of hair and non-hair cells. Epidermal cells overlying two cortex cells eventually develop a hair, while those overlying only one cortex cell do not. Here we propose a network model that integrates most of the available genetic an
