Sample GSM8019081 Query DataSets for GSM8019081
Status Public on Feb 01, 2024
Title AP64, 10% O2, 2 hours after the shift to light, rep3
Sample type SRA
 
Source name AP64
Organism Gemmatimonas phototrophica
Characteristics tissue: AP64
genotype: WT
treatment: 2 hours after the shift to light, 10% O2
Treatment protocol After reaching approx. OD600 = 0.2 cultures were illuminated with photon flux density of 100 µmol photons m-2 s-1 for 2 and 8 hours
Growth protocol G. phototrophica AP64T (= DSM 29774) was grown in an optimized liquid medium described earlier (Shivaramu et al., 2023) at 25°C. At the beginning of each experiment, the inoculum (approx. OD600 = 0.2) was diluted in 100 mL of a fresh medium to approx. OD600 = 0.03. Cultures were grown in triplicates at dark aerobically (20% O2) or semiaerobically (10% O2).
Extracted molecule total RNA
Extraction protocol Cells from triplicate cultures were harvested by centrifugation, resuspended in 1 mL PGTX extraction solution (Pinto et al., 2009) and immediately frozen in liquid nitrogen. RNA was extracted as described earlier (Kopejtka et al., 2020).
Libraries were generated according to the protocol of Shishkin et al. (2015) including rRNA removal with the RiboZero Kit (Illumina, USA) and sequenced on a NovaSeq 6000 (Illumina, USA) in paired-end mode with 100 cycles in total.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Description 2L6
Data processing Raw reads were processed, and differential gene expression was assessed as described before (Kopejtka et al., 2020).
Quality filtered reads were mapped to the G. phototrophica AP64 genome (GenBank accession number GCF_000695095.2) using bowtie2.
Normalization and identification of significantly differentially regulated genes (FDR < 0.01) was performed with edgeR.
Assembly: GCF_000695095.2
