Sample GSM2471776 Query DataSets for GSM2471776
Status Public on Jul 03, 2017
Title IST rep 2 MPI
Sample type SRA
 
Source name Seedling
Organism Zea mays
Characteristics tissue: inner stem tissue V2 seedling
line: B73
Treatment protocol V2 Seedlings were dissected to extract the inner stem tissue: the outer leaves, including sheath, and also exposed leaf blades were removed. Soft husk leaves were obtained after longitudinal section of the husk including ear, removal of the ear tissue as well as the lignified most external husk leaves layers.
Growth protocol B73 maize plants were grown till stage V2 (Abendroth et al 2011) or till flowering (ears with emerging silks, before pollination) in greenhouse (16h of light per day, temperature above 22°C)
Extracted molecule total RNA
Extraction protocol Plant tissues were ground in liquid Nitrogen and total RNA were extracted using TRIzol in combination with Quiagen RNeasy Plant kit.
A total of 500 ng of total RNA was treated with the Ribo-Zero rRNA Removal Kit, Plant Leaf (Epicentre) to specifically remove ribosomal RNAs. RNA-seq libraries were prepared with the NEBNext Ultra Directional RNA Library Prep Kit for Illumina (New England Biolabs) following manufacturer’s protocol. Quality and quantity was assessed at all steps by capillary electrophoresis (Agilent Bioanalyser and Agilent TapeStation). Illumina Sequencing-by-synthesis libraries were quantified by fluorometry, immobilized and processed onto a flow cell with a cBot (Illumina) followed by sequencing-by-synthesis with TruSeq v3 chemistry on a HiSeq2500
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Description (rRNA depleted)
Data processing Basecalls performed using Illumina’s real-time analysis software (RTA).
Quality filtering of RNA-seq reads were done using Trimmomatic (Q20).
RNA-seq reads were aligned to the AGPv4 genome assembly using Tophat.
RNA-seq reads were assembled using Cufflink.
Gene expression level calculation and differential expression analysis was done using Cuffdiff.
Note: The strand polarity of the raw data at SRA is reversed.
Genome_build: AGPv4.32
Supplementary_files_format_and_content: Tab-delimited file containing gene expression level (FPKM) and differential expression data from Cuffdiff.
