Sample GSM2446254 Query DataSets for GSM2446254
Status Public on May 01, 2018
Title Co-culture replicate 2, 13:11 day:night cycle -> extended darkness, Time 144
Sample type SRA
Source name Bacterial co-culture, extended darkness, 144hr
Organisms Alteromonas macleodii; Prochlorococcus marinus str. NATL2A
Characteristics p. marinus strain/background: NATL2A
a. macleodii strain/background: MIT1002
condition: 13:11 light:dark light cycle -> extended darkness
timepoint: 144 hours
Treatment protocol Cultures were split after 24 hours of sampling under the day:night light cycle; at 'sundown', half experienced the normal light regime, the other half stayed in the dark.
Growth protocol Cultures were grown in natural seawater-based PRO99 media under a 13:11 day:night light cycle.
Extracted molecule total RNA
Extraction protocol Culture samples added to cold RNAlater at each timepoint, cells collected onto a 0.2µm filter, and total RNA extracted with the mirVana kit (Ambion).
Strand-specific RNA-seq library construction starting with 100ng of total RNA using the dUTP second-strand approach; duplex-specific normalization was performed to reduce ribosomal RNA content in each sample.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
Description H144D_2
Processed data file: extended_darkness_counts.txt
Data processing Low-quality sequence removed using quality_trim (CLCbio) using default parameters.
Alignment of paired-end reads to references using the Burrows-Wheeler Aligner V0.7.12.
Number of aligned read pairs mapping in the sense orientation to each ORF determined using HTSeq (Anders, S., Pyl, P. T., & Huber, W. (2014). HTSeq–A Python framework to work with high-throughput sequencing data. Bioinformatics (Oxford, England)).
Genome_build: NCBI accessions CP000095.2 (Prochlorococcus marinus) and JXRW01000000.1 (Alteromonas macleodii).
Supplementary_files_format_and_content: extended_darkness_counts.txt: Tab-delimited text file with the number of reads mapping to each ORF for all timepoints and replicates, as well as associated annotation data.
