Fig. 5From: Glutamine rapidly induces the expression of key transcription factor genes involved in nitrogen and stress responses in rice rootsGlutamine may function as a signaling nutrient in plants. Glutamine entering the plant cell can be directly used for metabolism to support plant growth and development. The internal glutamine and nitrogen status may affect gene expression in the nucleus. In addition, plants may be able to sense the external glutamine and nitrogen status to regulate gene expression.
