Sample GSM8385719 Query DataSets for GSM8385719
Status Public on Jul 15, 2024
Title gCPT1
Sample type SRA
 
Source name Brassica napus seed chalaza
Organism Brassica napus
Characteristics cultivar: Topas
tissue: Brassica napus seed chalaza
genotype: Brassica napus cv. Topas
Treatment protocol Flowers were hand pollinated at the time of anthesis during the times of 14:00 - 17:00. Siliques were collected at 0 (ovule), 7 (globular), 10 (heart), and 28 (mature green) days after pollination. Tissue was fixed in 1:3 (v/v) glacial acetic acid: 85% ethanol for 24 h at 4°C. Tissue was dehydrated in a graded ethanol series, then infiltrated with molten parrafin wax at 60°C. Tissue was then embedded in 100% paraffin wax and 7 µm sections were cut onto polyethylene napthalate membrane slides for LMD. Sections were deparaffinized and subregions were dissected and isolated out using LMD.
Growth protocol B. napus plants were grown in growth chambers nder long day cycles (16 h light, 8 h dark, 22°C, RH 50%–70%)
Extracted molecule total RNA
Extraction protocol Once dissection was completed, total RNA was extracted using Ambion RNaqueous micro kit with Qiagen RNAse-free Dnase to remove genomic DNA. RNA quality was evaluated using an Agilent Bioanalyzer. Minimum RIN of 3 was required for further processing.
Fragmentation was conducted via Covaris ultra-sonicator. Library preparation was done with NuGen Ovation Multiplex System. Libraries were quantified and assessed in quality via Quant-iT PicoGreen dsDNA assay kit, qPCR, and the High Sensitivity DNA analysis kit (Agilent) on the Agilent 2100 Bioanalyzer. Libraries were pooled and size selected at 350-600 bp on an E-Gel (Invitrogen). Samples were sequenced on the Illumina HiSeq 2000 platform.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing low quality reads were trimmed and aligned to the B. napus cv. Topas reference genome using hisat2. Quantification of uniquely mapped reads were done using the featurecounts package. Counts were normalized to TPM.
Assembly: Brassica napus cv. Topas
Supplementary files format and content: Tab delimited text file of normalized TPM values. Raw data uploaded to SRA.
