Sample GSM6427760 Query DataSets for GSM6427760
Status Public on Jan 04, 2023
Title Root_1%DMS_OsNRT1.1B
Sample type SRA
 
Source name rice roots
Organism Oryza sativa Japonica Group
Characteristics tissue: Root
age: Two-week-old
target: OsNRT1.1B
Treatment protocol Two-week-old rice seedlings were collected and immersed in 20ml of 1X DMS reaction buffer (40mM HEPES pH7.5, 100mM KCl and 0.5mM MgCl2). 200µl of DMS was added to the reaction buffer to give a final concentration of 1%.The same volume of DEPC-treated water was added into the reaction buffer for the mock treatment. DMS treatment was performed for 15 min at 30°C with shaking at 250rpm.
Growth protocol Two-week-old rice (Oryza sativa ssp.Nipponbare) seedlings grown in hydroponic nutrient solution
Extracted molecule total RNA
Extraction protocol DMS-treated or DMS-Untreated samples were pelleted and resuspended in 1 mL Trizol, RNA was extracted by phenol-chloroform extraction and isopropanol precipitation.
For target-specific DMS-MaPseq, 3 µg of DMS-treated sample was mixed with gene-specific RT primers. The reverse transcription was proceeded with TGIRT-III (Ingex). Then specific gene cDNA were amplified using KOD hot start DNA polymerase with gene-specific primers.The mixture was incubated under vacuum for 5 min at room temperature. The samples were then washed three times with 50 mL of DEPC-treated water each, frozen in liquid nitrogen, and ground to fine powder.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Data processing For filtering the raw fastq files, Trimmomatic was used to remove adapter sequences. A sliding window trimming approach was used to filter the reads with quality scores lower than 20. Next, 2 nt from the 5′ end of each read were trimmed, and the reads over 200 bp were kept for further analysis.
Reads were aligned to the reference sequence using TopHat with parameter setting: --library-type fr-unstranded --no-novel-juncs -N 25 --read-gap-length 7 --read-edit-dist 25 --max-insertion-length 5 --max-deletion-length 5 -g 3 --no-mixed.
Mismatch count and coverage in each nuclotide were called, and mismatches located within 3nt of an insertions or deletion were masked for future analysis.
