A simple model of the drought stress responses in foxtail millet. Foxtail millet can perceive duought stress signals by putative sensors and transmit them to the cellular machinery by signal transduction to regulate gene expression. Through regulation of transcription, protein synthesis and processing, the abundance and activities of functional proteins involved in stress and defense response, energy pathways and a variety of metabolism pathways were changed. These processes might work cooperatively to establish a new cellular homeostasis under drought stress
