The list of up regulated genes in the comparison of the rhizome related DEGs.

aA∼G represent the expression level of the 7 gene sets including DEGs of rhizome tip verse shoot tip in O. longistaminata from transcriptome sequencing data (A), microarray analysis data (C) and results of the present study in Sorghum propinquum (E), DEGs of underground tissues (rhizome tip and rhizome internode) verse above ground tissues (shoot tip, shoot internode and young leaf) in O. longistaminata from transcriptome analysis (B), microarray analysis (D) and results of the present study in Sorghum propinquum (F), and candidate rhizome-enriched genes in S. Halepense (pSH) and S. propinquum (G).
