From: Role of myo-inositol during skotomorphogenesis in Arabidopsis
A model based on findings and published data. During hook formation, MI induces the ethylene response which induces brassinosteroid response, however this results in inhibition of MI synthesis. Differential distribution of auxin is maintained via MI through PIN protein. It is therefore MI is one of the important regulators of apical hook formation, maintenance and opening.
