|
| Organism |
Mycobacterium marinum |
| Characteristics |
strain: M
tissue: bacterial cultures
genotype: B11-deletion
treatment: pSMT3 carring B11 under its native own promoter
|
| Growth protocol |
7H9 broth plus 10% OADC
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Bacterial cultures (4 mL) were mixed with 0.2 volumes of stop solution (95% ethanol and 5% phenol) and immediately frozen in liquid nitrogen. Total RNA was isolated using the Trizol method, wherein cells were resuspended in 1 mL Trizol (Invitrogen) and 0.2 mL 0.1mm Zirconium/Silica beads (Biospec) for lysis. Bacterial lysis was achieved using a Precellys 24 homogenizer (4500 rpm, 3 cycles of 30 seconds, separated by 5-minute intervals on ice). After addition of 400 μL chloroform and centrifugation in a Phase Lock Gel tube (TIANGEN Biotech) at 13,000 rpm for 15 min, 500 μL of the aqueous phase was mixed with 450 μL isopropanol and precipitated at room temperature for 30 min. The RNA pellets were then washed with 80% ethanol, dissolved in ultra-pure water (Thermo Fisher Scientific), and the RNA concentration was determined using a NanoDrop 2000 (Thermo Fisher Scientific).
Ribosomal RNAs was removed by Biotin-labeled rRNA probe. RNA was fragmented with BGI fragmentation buffer and was reverse transcribed with random hexamer. Double chain cDNA was then blunted and phosphorylated for the 5’ end, and overhang A base in the 3’ end and ligated with T-overhang adapter. After PCR application, samples were sequenced in BGISeq-500 platform

| Description |
B11-deletion M.marinum M strain plus pSMT3 carring B11 under its native own promoter
|
| Data processing |
RNA-seq was performed by BGI Group, Shenzhen, Guangdong, China. Briefly, a strand-specific cDNA library was constructed for each sample to keep the direction of RNA transcription. The obtained cDNA libraries were sequenced on an Illumina HiSeq 4000 machine.
SOAP (v2.21, -m 0 -x 1000 -s 28 -l 32 -v 5 -r 1 -p 3).The rest reads with adaptor，or with unknown bases more than 5% ,or with more than 20% low-quality bases were cleared by a software developed by BGI group. After, clear reads were mapped to reference genome with Bowtie2： v2.2.5 -q --phred64 --sensitive --dpad 0 --gbar 99999999 --mp 1,1 --np 1 --score-min L,0,-0.1 -I 1 -X 1000 --), and expression value was caculated (http://deweylab.biostat.wisc.edu/RSEM）
