Sample GSM6857948 Query DataSets for GSM6857948
Status Public on Mar 01, 2023
Title Water-stressed 24 h cotton primary root tip replicate 2
Sample type SRA
 
Source name Cotton Primary Root Tip
Organism Gossypium hirsutum
Characteristics tissue: Root
genotype: AU90810
Treatment protocol The media were set at water potentials of -0.02 MPa (well-watered treatments, WW), -1.0 MPa (water-stressed treatments, WS), which were obtained by mixing with certain amounts of 1 mM CaSO4. No further water supplies were added after the transplanting.
Growth protocol Cotton (cv. AU90810) seedlings were cultivated in a vermiculite culture system at well-watered (WW) and water-stressed (WS) treatments. Seedlings were grown at 29 oC and near-saturation humidity in a dark growth chamber until harvest. The root tips of cotton were harvested at 24 h and 48 h after transplanting to well-watered or water-stressed media. Transplanting and harvesting were performed using a green ‘safe’ light. Root tips containing the whole elongation zones of cotton (12 mm for WW; 6 mm for WS) primary roots were collected.
Extracted molecule total RNA
Extraction protocol Cotton root tip samples (12 mm for WW; 6 mm for WS) were collected from seedlings and immediately frozen in liquid nitrogen and pooled to generate 50-100 mg FW per sample. Total RNA was isolated using Qigen Plant RNeasy mini kit.
RNA libraries for sequencing were prepared using standard Illumina protocols.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Data processing Sequencing were performed by MU Genomics Technology Core
Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to Gossypium hirsutum NAU-NBT v1.1 whole genome using Hisat2 (v1.0).
Read counts were calculated using Htseq-count (v0.6.1), counting how many aligned reads overlap the exon of each gene (Anders et al., 2015).
Assembly: Gossypium hirsutum NAU-NBT v1.1
