| Source name |
leaf
|
| Organism |
Nicotiana tabacum |
| Characteristics |
tissue: leaf
genotype: PMT RNAi suppresion
treatment: topped
|
| Extracted molecule |
total RNA |
| Extraction protocol |
With use of liquid nitrogen, tobacco samples were grinded to fine powder in mortars, and 200-mg samples were taken for RNA extraction. RNA extraction was performed by RNeasy® Plant Mini Kit (© QIAGEN N.V., Venlo, the Netherlands).
Subsequenlt sequencing library preparation was performed (no fragmentation) by TruSeq® Stranded Total RNA Gold (© Illumina, Inc., San Diego, CA, USA).

| Description |
PMT2 root sample bio rep 2
|
| Data processing |
The generated sequencing data were demultiplexed by Illumina BaseSpace® Clarity LIMS (© Illumina, Inc.) and subsequently imported to Qiagen CLC Genomics Workbench version 11.0.1 (CLC bio, a QIAGEN Company). Transcriptome reads were mapped to updated version the N. tabacum reference genome [49] using the ‘RNA-Seq Analysis’ 2.16 tool with similarity of 0.95 (S=0.95) and fraction length of 0.95 (L=0.95) as mapping criteria. The mismatch, insertion, and deletion costs were set to 2, 3, and 3, respectively.
Global alignment was not performed, and paired distances were detected automatically. The maximum number of read hits was set to 10, and paired reads were counted as 2. RPKM values were retrieved for each gene in the reference genome, including for those without transcript models. A fusion gene table was not created.
For each sample principal component analysis (PCA) was performed with the CLC ‘PCA for RNA-Seq’ tool. Gene expression analysis was performed with the ‘Empirical Analysis of DGE’ tool, where RPKM values for each gene were retrieved and compared by empirical analysis of DGE, which employs the ‘exact test’ developed by Robinson and Smyth [50] that was incorporated into the EdgeR Bioconductor package [51]. Genes with pairwise comparison p-values ≤0.05 and an absolute fold change ≥2 were regarded as significantly different.
