Sample GSM7804800 Query DataSets for GSM7804800
Status Public on Sep 11, 2024
Title hen1-1_inflorescence_sRNA-seq
Sample type SRA
 
Source name inflorescence
Organism Arabidopsis thaliana
Characteristics tissue: inflorescence
genotype: hen1-1
ecotype: L.er
library type: conventional sRNA-seq
Treatment protocol None
Growth protocol The seeds were grown in soil. After cultivated in 4 ℃ for three days, the seeds were transferred to 16/8 h (light/dark) greenhouse.
Extracted molecule total RNA
Extraction protocol Total RNAs were extracted from inflorescence tissues using TRIzol reagent (Invitrogen, USA) following standard protocols. For "conventional sRNA-seq" library, total RNA was separated in 16% denaturing PAGE gel to excise 18-30 nt, and gel purified RNA was treated by NaCl solution. For "NaIO4 treatment" library, total RNA was separated in 16% denaturing PAGE gel to excise 18-30 nt, and gel purified RNA was treated by NaIO4 solution. For "PBA-PAGE" library, total RNA was separated in 16% denaturing PAGE gel supplemented with 2% PBA to excise 18-30 nt, and gel purified RNA was treated by NaCl solution. For "TRM-sRNA-seq" library, total RNA was separated in 16% denaturing PAGE gel supplemented with 2% PBA to excise 18-30 nt, and gel purified RNA was treated by NaIO4 solution. For AGO1-RIP samples, protein was extracted from Col-0 inflorescence. After immunoprecipitation, AGO1-bound RNAs were isolated by phenol-chloroform extraction and ethanol precipitation.
All types of small RNA libraries were constructed using the NEBNext Multiplex Small RNA Library Prep Set for Illumina (NEB, USA) following manufacturer's instructions and purified using Monarch PCR & DNA kit (NEB, USA).

Description hen1-1 CK
Data processing Sequence reads were trimmed for adaptor sequence/low-quality sequence using trim_galore (version 0.6.6).
Trimmed sequence reads were mapped to TAIR10 using ShortStack (version- 3.8.5 parameters- --align_only –nohp --mmap u --bowtie_m 1000 --ranmax 50 --mismatches 0).
Reads count extraction was performed using featureCounts (version- v2.0.1 parameters- -O --largestOverlap -fraction).
Reads count normalization was performed using DESeq2 and custom R scripts.
Assembly: TAIR10
Supplementary files format and content: Tab-delimited text files include sequence counts for each Sample.
