From: Identification of Gossypium hirsutum long non-coding RNAs (lncRNAs) under salt stress
The abundance of specifically expressed lincRNAs (RPKM) and protein-coding genes across 4 samples. The rows and columns were ordered according to Cluster3.0. a, 44 specifically expressed lincRNAs.; (b), 262 salt-responsive transcription factor protein coding genes and salt tolerance-related genes. Unigene expression values are scaled ranging from + 3 (red) to − 3 (green); S_CK is the average of S_CK1 and S_CK2; S_NaCl1 is the average of S_NaCl1and S_NaCl2. Red represents up-regulated protein coding genes, green represents down-regulated protein coding genes and black indicates no expression of the unigene in the sample. And more details were shown in Additional file 5
