| Title |
Callus I rep2 |
| Sample type |
SRA |
| |
|
| Source name |
Callus
|
| Organism |
Sorghum bicolor |
| Characteristics |
strain: Hiro-1
tissue: Callus
age: 3 weeks callus induced from young embryo,and additional 20 days subculture
genotype: wild type
phenotype: Callus I
|
| Growth protocol |
Sorghum bicolor (L.) Hiro-1 were used in this study. Young embryos (about 1-2 mm) were collected from 13-15 day-old plants after flowering, and subsequently inoculated on callus induction medium (CIM) and cultured under sterile and non-light conditions at 25 °C. After 3 weeks, after removing the buds and outer membranes of the immature embryos, three types of callus was excised from the explants, and separately transferred to the new CIM for additional 20 days subculture before being moved into differentiation medium and cultured under condition of 16/8 h of light/dark at 25 °C and 2000 lx of light intensity.

| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from Callus I, Callus II, Callus III and leaves generated from Callus II by using Trizol reagent (Invitrogen). Four RNA samples were then separately subjected to transcriptome analysis using Illumina sequencing with two biological replicates.
RNA libraries were prepared for sequencing using standard Illumina protocols

| Data processing |
RNA-seq data were first cleaned by removing contaminations and low quality reads by Trimmomatic. The clean data were aligned with Tophat 2.0 (Kim et al., 2013) using the Phytozome Sorghum bicolor (BTx623) genome as the reference under default parameters (Paterson et al., 2009). Then, the gene counts were calculated with Cufflink, and the differentially expressed genes (greater than 2, P value < 0.05) were calculated by Cuffdiff. The up- or down-regulated genes were subjected to GO analysis and KEGG analysis to see which pathways the differential gene function was concentrated on.
