Sample GSM5515897 Query DataSets for GSM5515897
Status Public on Sep 11, 2021
Title Top Internode section of the maize stem, rep 2
Sample type SRA
 
Source name Puma hybrid maize
Organism Zea mays
Characteristics genotype: Puma hybrid
developmental stage: 60 DAS before pollination
tissue: Top internode section of the stem
Growth protocol Puma hybrid maize plants were grown in 10 L plastic pots containing 1/1 v/v peatmoss and vermiculite sterile soil mixture under greenhouse conditions. Plants were collected at early reproductive stage R1 (60 DAS). Tissues collected were the top internode section of the stem, TI. And the female inflorescences (FI) which were bagged prior to silk emergence. Samples were frozen, milled with Restch mill in liquid nitrogen and storage at -80°C.
Extracted molecule total RNA
Extraction protocol Total RNA from female inflorescences (FI) and top internodes of the stem (TI) at 60 DAS were extracted using the PureLink RNA-micro-to-midi Kit (Invitrogen Corp., Carlsbad, CA, USA) as described by the manufacturer. The purity and integrity of RNA samples were evaluated by electrophoresis on 2% RNase-free agarose gels, spectrophotometry (A260/A280 and A260/A230 ratios) using a NanoDrop 2000 (Thermo Scientific) and quality analysis using the Agilent 2100 Bioanalyzer system (Agilent technologies, Inc, USA).
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina MiSeq
 
Data processing RNA-seq read quality was assessed with FastQC v0.11.2 and cleaned using the Trimmomatic software (Bolger, Lohse & Usadel, 2014).
Reads were aligned to the maize B73 reference genome (ZmB73_RefGen_v3.25, www.maizegdb.org) using the TopHat v2.0.13 software.
The expression level was calculated in fragments per kilobase of transcript per million fragments mapped (FPKM) as described previously (Trapnell, Pachter & Salzberg, 2009; Trapnell et al., 2012).
Data analysis were updated using CLC Genomics Workbench 20.0 (QIAGEN) software mapping to the B73 reference genome v4 .
Only the genes with FPKM results that met the criteria of FDR <0.05 and fold change > |2| between the two conditions were considered to be significantly differentially expressed
