Sample GSM5100264 Query DataSets for GSM5100264
Status Public on Mar 23, 2021
Title RNAs from seed produced at 23°C_germination IV stage, ros_1
Sample type SRA
 
Source name RNAs from seed produced at 23°C_germination IV stage
Organism Arabidopsis thaliana
Characteristics genotype: ros1-4
developmental stage: seed germination IV stage
treatment: growing control conditions 23°C
tissue: entire seed
Treatment protocol After bolting and first flowers, control plants were grown at the same temperature condition 24°C/22°C (23°C) but stressed plants were transferred to another culture room with mild stress conditions 26°C/24°C (25°C) and severe stress conditions 28°C/26°C (27°C)
Growth protocol Plants were grown in a culture room in trays containing a sterile soil at 20°C/18°C, with a 16 h light photoperiod at 200 μmol photons m -²s-².
Extracted molecule total RNA
Extraction protocol Total RNAs were extracted from the frozen grinded tissues lots using the Macherey-Nagel NucleoSpin RNA Plus kit (Macherey-Nagel, GmbH & Co. KG, Germany) following manufacturer’s instructions
Samples were sent to BGI, Hong Kong, for library preparation. Libraries were constructed following a custom protocol from samples that passed quality controls (mass > 2µg, concentration>80ng/microl, OD260/280 ~= 2.00, OD260/230 ~= 2.20, RIN>6.5, 28S/18S<1.0, baseline smooth). After mRNA enrichment, RNA was fragmented and reverse transcribed to double-strand cDNA (dscDNA) by N6 random primer. The synthesized cDNA was subjected to end-repair and then was 3’ adenylated. Adaptors were ligated to the ends of these 3’ adenylated cDNA fragments. The ligation products were purified and many rounds of PCR amplification were performed to enrich the purified cDNA template using PCR primer, splint oligo and DNA ligase, followed by sequencing on BGISEQ-500 platform, generating an average 24M reads of 50bp per sample

Data processing The sequencing data was filtered with SOAPnuke (v1.5.2) [1] by (1) Removing reads containing sequencing adapter; (2) Removing reads whose low-quality base ratio (base quality less than or equal to 5) is more than 20%; (3) Removing reads whose unknown base ('N' base) ratio is more than 5%, afterwards clean reads were obtained and stored in FASTQ format.
