Sample GSM4429225 Query DataSets for GSM4429225
Status Public on Mar 24, 2020
Title 144RS15
Sample type SRA
 
Source name fully expanded leaves
Organism Brachypodium distachyon
Characteristics genotype: Bd21
cultivar: Bd21-3
tissue: fully expanded leaves
photoperiod: SD (12 h light/12 h dark)
temperature: 20ºC
replicate: single
time: collected after 3 weeks at ZT16
Growth protocol Seeds were imbibed in distilled water at 4 ºC for two days before sowing. Plants were grown in 5 parts John Innes #2, 3 parts peat, 1 parts silver sand, 3 parts course vermiculite, Osmocote 2.7 g/L. All plants were grown in growth cabinets in SD (12 h light/12 h dark) with constant temperature 20ºC, 65 % humidity and 350 μmol m-2 s-1 PPFD (Photosynthetic Photon Flux Density). Samples were collected after 3 weeks at ZT16 by snap-freezing in liquid nitrogen.
Extracted molecule total RNA
Extraction protocol Qiagen RNeasy Mini Kit (74104) was used to extract RNA. RNA quality and integrity were assessed on the Agilent 2200 TapeStation system.
Library preparation was performed with 1µg total RNA using the NEBNext® Ultra™ Directional RNA Library Prep Kit for Illumina® (E7420L). The libraries were sequenced on a NextSeq500 (Illumina) running a final pooled library. Each pool contained 24 to 30 samples and was sequenced using NextSeq® 500/550 High Output Kit v2 (150 cycles) TG-160-2002 on a NextSeq500 (Illumina).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Data processing genome build: Bd21-v3.1
Adapters were trimmed off using Trimmomatic with "ILLUMINACLIP:$FA_ADAPTER:2:10:5:1"
The trimmed reads were aligned using Tophat with "--max-multihits --library-type fr-firststrand --no-mixed"
Duplicate reads were removed with Picard using default setting
Alignments in SAM file were assembled into transcripts abundances using htseq-count with "-r name -s no -f bam -t exon -i gene_id" against the GTF annotation"
Supplementary_files_format_and_content: _htseq_count.ct.txt: TSV table containing htseq-counted transcript abundances.
