Fig. 3From: Glutamine rapidly induces the expression of key transcription factor genes involved in nitrogen and stress responses in rice rootsRT-PCR analyses of glutamine-responsive genes. Total RNA extracted from roots of 17-day-old glutamine-treated rice seedlings was used for RT-PCR analysis to verify the expression of 35 genes identified by microarray analysis. a Transcription factor genes. b Kinase or signal transducer genes. c Metabolic or transporter genes. d Stress response or unknown function genes. The expression levels of EF1α in the same samples are shown as a controlBack to article page
