Sample GSM2051197 Query DataSets for GSM2051197
Status Public on Jan 24, 2019
Title JLDD4ABV4 Biological Replicate #2
Sample type SRA
 
Source name Chlamydomonas reinhardtii 4A+ wild-type
Organism Chlamydomonas reinhardtii
Characteristics strain: 4A+
treatment: 0.1 mM
light: 4h white light
Treatment protocol Cells (4A+, hmox1, ho1C1 or ho1C2) were innoculated in TAP medium (containing 0.5% v/v methanol with or without 0.1 mM BV IXα) at 5×104 cells/ml and grown in the dark at 22 C until the cell density reached ~2×106 cells/ml and then illuminated with white light (150 µmol photons m-2 s-1) for 30 minutes. Cells were harvested before and after light treatment and total RNA was extracted with Trizol and Qiagen RNeasy mini kit.
Growth protocol All strains were maintained on TAP (Tris-Acetate-Phosphate) plates with modified recipe of trace metal elements {Kropat, 2011} at room temperature (22 C) under continuous illumination (30 μmol photons m−2 s−1). Liquid cultures were grown on a gyratory shaker (~100 rpm) heterotrophically on TAP medium in darkness.
Extracted molecule total RNA
Extraction protocol Total RNA was prepared as described previously {Castruita, 2011} and RNA quality was assessed by an Agilent 2100 Bioanalyzer at the UC Davis Genome Center. RNA-Seq libraries were sequenced as single-end 100mers using the HiSeq platform from Illumina.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description Illumina's RNA-Seq whole transcriptome analysis
Data processing Illumina Casava1.8 software used for basecalling.
The STAR aligner (v2.3.0) was used to generate the genome index and perform alignments in single-end mode. Reads were aligned to a genome index that included both the genome sequence (Chlamydomonas reinhardtii v5.5 assembly) and the exon/intron structure of known gene models (Augustus 11). Relevant alignment parameters included: multimapping score range=0.66, minimum alignment length=75%.
Alignment files were used to generate gene-level count summaries with HTSeq (unique hits and “intersection-strict” mode for version v0.6.1p2).
Genome_build: version 5.5 assembly of the Chlamydomonas genome
Supplementary_files_format_and_content: Per-library expression estimates in units of FPKMs.
