| Title |
K326-3 [K_3] |
| Sample type |
SRA |
| |
|
| Source name |
Leaf
|
| Organism |
Nicotiana tabacum |
| Characteristics |
tissue: Leaf
age: 45 days after transplantation
genotype: K326
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from the tissue using TRIzol® Reagent (Plant RNA Purification Reagent for plant tissue) according the manufacturer’s instructions (Invitrogen) and genomic DNA was removed using DNase I (TaKara). Then RNA quality was determined by 2100 Bioanalyser (Agilent) andquantified using the ND-2000 (NanoDrop Technologies). Only high-quality RNA sample(OD260/280=1.8~2.2, OD260/230≥2.0, RIN≥6.5, 28S:18S≥1.0, >1μg) was used to construct sequencing library.
RNA-seq transcriptome librariy was prepared following TruSeqTM RNA sample preparation Kit from Illumina (San Diego, CA) using 1μg of total RNA. After quantified by TBS380, paired-end RNA-seq sequencing library was sequenced with the Illumina HiSeq xten/NovaSeq 6000 sequencer (2 × 150bp read length)

| Data processing |
The raw paired end reads were trimmed and quality controlled by SeqPrep(https://github.com/jstjohn/SeqPrep) and Sickle (https://github.com/najoshi/sickle) with default parameters.
Then clean reads were separately aligned to reference genome（https://solgenomics.net/organism/Nicotiana_tabacum/genome） with orientation mode using HISAT2 (http://ccb.jhu.edu/software/hisat2/index.shtml)software.
The mapped reads of each sample were assembled by StringTie(https://ccb.jhu.edu/software/stringtie/index.shtml?t=example) .
RSEM （http://deweylab.github.io/RSEM/）establishes the maximum likelihood abundance estimation model based on the maximum expectation algorithm, and considers the paid end reads, the length of reads, the length distribution of fragments, and the quality value to distinguish which transcripts are different subtypes of the same gene. The results of expression quantification are expressed in TPM/FPKM. The homogenization process of TPM/FPKM makes the total expression amount in different samples consistent.
