Sample GSM8046464 Query DataSets for GSM8046464
Status Public on May 14, 2024
Title small RNA-seq:Il14H-2mm-rep4
Sample type SRA
 
Source name anther
Organism Zea mays subsp. mays
Characteristics group: Il14H-2mm
cell type: anther
genotype: Il14H
molecule subtype: small RNA - total
Extracted molecule total RNA
Extraction protocol Fresh anthers were snap-frozen in liquid nitrogen and total RNA was extracted using the TRI reagent (Sigma-Aldrich) or the TraPR Small RNA Isolation kit (Lexogen; for TraPR sRNA-seq only)
sRNA-seq libraries were prepared from ~100 ng total RNA per sample using a Somagenics RealSeq-AC miRNA library kit following the manufacturer’s protocol. RNA-seq (Smart-seq2) and nanoPARE libraries were prepared from 5 ng total RNA per sample using the nanoPARE library preparation protocol.
 
Library strategy ncRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model NextSeq 550
 
Data processing To quantify phasiRNA abundance, sRNA-seq reads were mapped to the respective Zea genomes using Bowtie v1.3.1; to quantify miRNA abundance, sRNA-seq reads were mapped to a FASTA file of all mature miRNAs annotated for each genome using bowtie; and to quantify mRNA abundance, Smart-seq2 reads were mapped to the respective Zea genomes (B73 RefGen_v5 was used for the ago18 mutant data) using HISAT v2.1.0. Reads mapped to PHAS loci or miRNAs were counted using featureCounts v1.6.3 and normalized to counts per million (CPM) using edgeR v4.0.2. Differential expression analyses were performed using edgeR with a generalized linear model-based method. Small RNA-transcript interactions in each anther sample were identified using the nanoPARE analysis pipeline (Schon et al., 2018). The sRNA-target pairs with adjusted P value < 0.05 at the EndCut step and are detected in at least two biological replicates were considered positive.
Assembly: Respective reference genomes of Zea varieties
Supplementary files format and content: CPM tables for sRNA-seq and RNA-seq, cleavage-site tables for nanoPARE
